A

Ok, I think the beginning here you have now it was so we start today or tomorrow. That would also ask for space, but he should know today and tomorrow.

B

A

Boss of twitter get comments, probably mostly comes first of course notice, because somehow the new system had to do yes there. I am short that say so. Many people say why do you have to do it at all? Why do you pay so much attention to the table? Whether saying style.

C

A

Maybe okay, but why do you want to have.

C

Unix line endings.

A

And why do you who have a trailer single trading julian at the.

C

A

Of the file, those are.

C

Pretty pedantic.

A

Rules to give, but if you just wanted to work in the open source world, there is somewhere to help with such rules like that. We expect, because probably not everyone.

C

A

Necessarily be here want to work with one eye source world, but I think it fits into the picture to learn that you just pay close attention to such things and, as I said, describe one writes.

C

A

D

A

Stress not for the machine, the compiler converts it and shoots.

C

We write our world for.

A

People important.

A

B

Can now continue.

A

With the chapter, then, you heard it and noticed that sounds complicated. They somehow told me this story and noticed that government is difficult in come together, so many cultures had not gotten to know, showed systems and june comes makes.

C

It somehow very structured.

B

A

Reasonable there are these 32 bitcoins and there are the atomic.

C

Units there first of all.

A

The places different characters also june took care not only about the drawings, but also many other things I had just said, write.

C

A

To example, left right top down, you can also have more influence and.

B

A

Have light exit again to your parents, then it doesn't hold up too things like that.

C

A

Mentioned g8, that is another very popular encoding of unicode, because we.

C

B

A

201 he succeeded when you look at prey memory, then you often give away a lot of space. Most of the characters are in the ascii area, so you actually need a far. Even if you think.

C

B

A

We are here in the west and we are privileged and don't use a mask area. But what is, for example, the Asian countries.

B

A

E

Any websites or anything else that is not much better if they.

A

Save the 32-bit grundmanns in their characters and anyway, no longer into them.

A

Put such asian characters over any larger characters, even if.

B

A

Somehow download asian wikipedia page the whole html.

B

C

A

Active of course, there.

C

A

A center jens, japanese artist somewhere, but still much bigger than ascii, so it can easily get wrong. We want somehow, if possible, on the mask sign for those in a bypass to that creates power, because it is a variable government. That means not. Everything is saved in 32 bits, but certain things will be included widely saved. Certain second saved the.

B

First picture from.

A

Just now indicates whether there are other people who know, and the great thing about this code point is that it is compatible with aspirin. Ass kee has set the first one to zero. That means, if unicode would read about it, it will just think okay. That sets the only other thing that belongs to this point. There Is it right to have been deported and as a team, just that then also right. That's very nice disadvantages already mentioned in relationship and difficult or the ranks.

A

Moody, difficult and I promised I 'll work again for other problems that came up on the first screen in the grid, and now we have a rough rough understanding of unicode and then a rough understanding of boeing and stuff like that.

C

I hope, then we can.

A

Finally, use the strings.

C

A

C

Such that you can.

A

C

A

As possible, not as easy as, e.g.

C

A

C

Know this uppercase.

A

String that only comes with the criticism. Everything is ready. That means that it is not built into.

C

The language not into the compiler, but that.

A

Could be written down, that is a type that could be written out that guarantees youtube you rast guarantee, so they open sting types almost guaranteed to make and that's pretty important and that.

B

A

Your work easier, then took is technically unbeaten with coding, that's in particular and string. That means it has in water that we already had a series of live tiles on Monday and signed the system that somehow owns his.

B

A

Which makes three of them, then it's out of the scope. It goes like this.

B

A

Example, it's basically a triplet.

C

A

Up of three data once it's longer like I, said it's all going to be extremely abbreviated length and.

B

A

Who got an idea? We need the capacity.

C

If you feel like.

C

A

Unfortunately, tend.

B

E

Other ideas for the time to go to bed. It can certainly be a cent for each character in the memory. Neither is excel stupid because it takes a lot of time to move the ebit. Even more capacity bones plugged in will be right. That.

A

I had already runs from the operating system, take care still save the best size requirements and we would like.

E

A

Strings for example, and always expand.

C

A

Them in the character, for example, then it is stupid to reserve only one memory block of exactly 1, but what is bigger is what.

C

You do every time and try over and if you had a call, only.

A

Shows that I don't want to do instead.

C

B

C

You are more and more.

A

Worried about the operating system, usually you.

B

Double the previous capacity and.

A

Then you can show it amortized in hofen 1. This is his somewhat extended location analysis that.

B

C

A

C

Speaking on average, that in.

A

Hof an 1, so the insertion is constant, so we.

B

Have this longer, this capacity.

A

B

A

The way the number is correct that not the letters, so not the number of characters, but really the paid. We see that are 6 now also know everything extensively and we have the second free places, so two more characters could be attached to.

C

A

Spring on these routes, and still we will finally repaint- and this deltas.

C

A

His friend the drinking water, if.

C

A

String somehow suspected what we mentioned.

C

A

Auto club goes then destroys its drinking water, and this guy is not whether that has already been mentioned to me briefly, because he will repeat it again or remember what happened if string profi.

B

Maybe someone will first say how.

A

Copy were defined what type.

F

Of vw technology can the two of the injured on some.

A

Can be labeled just as competently, and there will be a valid second instance if we copy the bit wise here. One speaks of these.

C

A

Only ever copied from the first level so this year, if we were to copy bit by bit, we would have this again, but we would have two or four whole stream butter. And this thing, if he goes as author scope, then.

B

The saalbacher and deletes the other one still.

A

Exists but shows whether this weapon is.

B

C

A

News on the free.

C

A

Then evaluates the image for when the second one also goes the scope and wants to release this memory area. Again, probably the route is there.

E

Now hear a few of these terms that overwhelmed me at the beginning.

A

Of this news of the free- and so there are 10 problems for him, I expect that.

B

We will leave something that.

A

Occurs naturally, fortunately, yes, that's why.

C

We ask ourselves what, if.

A

You want to borrow otherwise quietly. We.

C

Had tried last.

A

Time somehow so the federal.

C

A

Wants a string so the sound can be borrowed. It looks like this then, so we simply have another variable that references.

B

A

And the cover then decorates, the drinking water there are maybe and disadvantages. Of course, there is a.

A

B

Use this type, you can't change the.

A

Original, it's a youtube hit arc youtube drivers would and can we change the original but a youtube so.

A

First of all, I also that we may have to follow two to.

E

A

Bring the string object here once and then do the screening So. The first part of the refinancing that follows is actually always the refinancing, which probably doesn’t cost much in terms of performance, but it can happen every now and then, like a few, that you don’t.

B

Necessarily want, but is n’t the biggest problem with these things, the biggest the problem is rather that.

A

Namibia requires this written in capitals.

C

A

Asks the man from the operating system blogger and it trenc to save what you ask from the operating system. They are always on the neighborhood. What.

B

This stack difference is, we will explain in detail sometime.

A

Later, but you maybe you remember from about the year, was that most things were blocked after keeper was in and that as well as a cloud and the operating system are given to publicis fist. But this evaluation takes time. It just has to be the.

C

Memory is not a bridge, but.

A

One-Dimensional manage the operating system now, somehow the blocks.

C

Are put together again.

B

A

How it best fills.

B

In the gaps again, it is, of course, administrative work of.

A

Course, the operating system could just always remember one enemy and something is always allocated this.

C

Friend put workers, but something old.

A

Memory out, then it 's done further. The operating.

C

System has to put some work into it, querying the memory.

A

Operating system always takes time. That is not what you really want. In particular, there are strings that do not let live on the way. What else can we do.

F

A

If we want a direct reference to.

C

A

Trick want to have victims so quasi what a data is stored here. What should be.

B

A

A

C

A

A pointer to this memory area.

G

A

We don't need the capacity because we don't want to change it.

C

A

Because we don't need the targets, we don't want to jump to this. But why experiment? But the.

C

Length is needed, is it.

A

Really different than in c, for example, in c the first jumps are terminated with 0. That means.

B

At the end, there are 0 bytes.

A

So zewen knows that's why it's over, but that's grown a bit historically, actually is always better to save the length separately and rast has no hint at the end. So.

C

If we only have this.

B

Punch line see that iris hair.

A

Goes on but don't know how long is so.

B

A

Need the length okay so bolt strings as a solution.

C

A

Type called str sdr is.

B

A

Again also a guarantee is, but a so-called fear means there will be more detail. What such an office says later, but first I.

B

Know that as a special.

A

Category of types that is the right to be str, and that means because the compiler does not can know he's okay,.

E

A

Now, there's a reason for this guy said: okay.

C

That was very close.

A

To that means, there's.

B

Included the length- that's, of course, very nice for us.

A

We would be.

C

A

So if we also take.

C

An sdr as a reference here, then it looks as.

A

If we were second and the length since saved it could benefit the whole thing, there are basically 22 that is capitalized once saw him, and then this lowercase str with the vodafone, because without this anyway sub-forums you can hardly use it. So that means sometimes you ca, n't work so well. She actually has two jump type fits and.

C

Now you're, okay does.

A

It really make sense now what about the fabrication around? Why do we prefer to live that sound differently? What about string metal? These are the parts here. What.

C

A

You think it's somehow it has to be saved somewhere saved this string of characters where.

D

A

That someone or wants someone to know that.

A

E

A

E

A

E

A

But it's already in the right direction, with exactly the file that.

B

A

This, in which.

B

A

File or on earned systems, gls and the countries.

B

Just try it out now.

A

It is stored in the executable in the so-called dot data or dot aero data station. That is true,, however, only for the saxon world. I.

B

C

A

For sure also looks in the executive stored problem.

B

A

Time I'll see, if I can do it so quickly, that would of course, be particularly good. Then.

A

Make a new home.

A

Here now it's gone here too. That won't be special now more exciting, because I just climb the rhine world extra program.

A

That's not quite okay, that.

A

's pretty easy, because it's written correctly we'll just check it now, with this exe file that it somehow doesn't look like a normal cmd under windows, but that's just a terminal emulator under windows, so it works under windows. That's why another exe file comes out like this, and in this exe file I mean we can take a look at it and just endure it, but it doesn't do much with it.

A

A

Ok, I open my new terminal. We can continue in the background. There is no better possibility, namely it is called that so there is parents, do it here and there we want 10 still hand over helau. He comes all the way now a lot, and fortunately I can cancel that. Of course, this file is very, very large and there are also memories there.

A

Now there are machine commands in it and we have still tackled a lot, but now we can see if we can find a hello and actually, if we see in the executive itself, this helloworld is in it. That means, if you, for example, earlier when we started programming, he wanted to write a password secured into the program. Then you somehow said this to luther an input and then input is the same as manhattens drink.

A

He guessed everyone and that was then a password, and only then did I do something else that doesn't do anything in most languages, because something like that is very easy to read, execute executable.

A

That happens to me like an executable that 's kind of cheerful then, but that helps we don't necessarily have to load the operating system before it executes the program,. So before it executes. The execute is always completely in the memory,, so simply load the entire file into memory and then at some point the file must now start executing the.

A

But ultimately everything will be in the memory is loaded and also these string, liberals, which are then directly reduced in c or c++, for example,, are string, lateral, pointers to a character and that points to this memory area were loaded. What does.

F

A

Mean for us now that means for us that the string is always alive. The program is loaded force is started and only unloaded when it's finished.

C

A

For us, I'm just sorry, the runtime of the program groups lives that always that, of course, particularly nice. Don't expect us to solve a problem particularly easily. That's.

G

A good question to be.

A

More precise such references can always only be high stakes,, so you have to create them specifically hand over the length so that you can answer briefly,. So it is usually done for you and that.

B

Should then be somewhere after.

A

The compiler rests,, but, of course it has to know the length, you can't just do it now, conjuring up an sd like that and then adding.

C

A

Length so the us campaign,, for example, for swing laterale,. Does it like that there it is now a type str so and str, and the guest can of course write the gears directly in there. If we talk now borrowing trimester from his greeting, then.

B

The length is simply.

A

Instinct becomes that you can’t, do it any other way?

A

Ok, give me an easy course +, which of course sounds a bit crazy, since I said live tiles later, but don’t worry it’s a something different than this and string. Now I always write after the lines. These are type that it has a colon and a type is so ok. The type is eliminated now the consultant can create, and that is the type and str he is not.

A

My favorite ostrings lies, I think the offer there it 's a bit hard to say so, it's a type of sting slice and I created it because in this case it's just this method. Sss dr, that works a bit more complicated. Now. That's this feature again, that's all an expressionist. What.

C

A

Here, for example,, so here we can, for example, write a complicated calculation with many statements in the pool at the end and at the.

C

B

Would then decide the result of the calculation, of.

A

C

The calculation.

A

Results in this variable that he explains how that with the expressions are things is in expression, works. I hope that is clear. It makes a lot of sense that sometimes you somehow somehow outsource the calculation.

C

A

A certain value that you need or need later to your scope, so that everything that is needed for the calculation is then discarded again. Okay, but now you want it, we use it to arrange strings. Our calculation is just to create this and string that again of the sting type and now we'll do this here. He would now like to guess what could possibly happen that you could overcome the agency.

A

Some were unsure but reported first.

H

H

A

Told me that in that case it's the right thing to happen. The and b no longer lives on this schwaebisch go further.

D

D

D

D

D

A

That's also a good question. I said: yes, let it actually be our statement, but.

B

A

On that write, the right side of the same characters, but you can include statements, are other expressions and so a blog is shipped and in this blog expression we can have it on statements, and this blog.

C

A

View that it again I think a thing that we can evaluate, and it comes one more back, that's all it is, and this one that's a little bit of a blog and it is executed that the last klopp is returned as a value. That's then, first.

C

D

B

D

A

Runtime and a lot of time.

A

B

A

You're already complaining said and b.

C

A

Not long enough, not long enough for the time that would move, and he explains.

C

To you afterwards, so this is now.

A

An abbreviated error message then also explains to you in pretty good detail what how long lifespan it doesn't work now then, yes,.

F

A

Easier first into old age, then this board b would also keep the other spring alive and everything is correct for just one year, but this implicit sharing of things so.

B

A

Is somehow refinanced by all places exactly.

B

That doesn’t work.

A

And now this here, what does it think it is at all? This is called the so-called that you look at cities here. Is this explicit annotation of easy again, which we don't need for the time being? But maybe you also see something like that easy, a special, easy share that you can always name all the other. Easy are. Yes, you can express that are also bindings. An existing live tiles that you can not be explicit, but there are many different live cams that are known to the kampala, but we can make these static.

A

Ladders explicitly to the animals of this site have already said, live forever. These are by the way, on static variables in most programming languages, that always live on the single title books take so far. First of.

B

A

Exactly right, if we write such a veteran, is that the cheapest way to save the operation is the red deer, and then we already have this string with us in memory. That means it doesn't cost anything for us to do. It,, that's good,. Of course you do it,, which of course, costs what,, but.

C

Now, there's that too now, even.

A

If you were converted between string types,, so now it's mainly going to be secondaries from what's once the district read, which borrows it abroad. Somewhere, we have these nine tu's pink. The question.

C

A

Price in two directions, which we comment, which direction costs more performance in which direction costs us almost nothing, does.

F

F

Save it will have to work it.

A

F

A

Upwards, that's only two companies and downwards good. If it.

C

Copies this whole explosive.

A

Device because string wants to own his stream weapon so.

B

Have complete control over it and.

A

I can't take over that his is borrowed the drinking water. That means it has to be copied that works now, so the device goes down,, for example, with into this only works.

A

If it is very clear, what kind of type is expected right, now,, for example, here it is clear that it should now be a string, so we can use in or what will probably happen to you more often is that the pure function, you have a capitalized and stream, and if you call this function, then of course it is also very clear what he expects now that the manufacturer unfortunately knows this function knows something at this point, for the advice is in jean.

A

You can of course, never say that we will get it, but in two has too nothing to do with strings alone. But if we are clear about what he is expecting, then it works sometimes otherwise. Just use too string the bets that just.

C

An expensive operation that both are.

A

Equally expensive, but these streams live so take this city. Extreme slices, for example, rotates a guitar fourth week that costs time. The other.

B

A

Have such a great ring it then you usually just have to take this reference to it. It.

B

A

Works if it is very clear what is expected also say here, for example, as will sd expect you string slice expected. Then it is clear. If we send a circular, then it will be commented on in this type a bit strange, because actually, if we expect these experts here and it is of the type dodge string breast ring- but there is a special regulation- rost compiler- which I will explain later I'm going to do that now, all of a sudden it works in the core.

A

You can also transfer a range here, but that's, maybe not a good idea at all. I think that the exact dean and bytes. That means it can go wrong if your initiation offset is specified who sits in the middle of a coupon, because it doesn't have the Japanese character or something like that, then it breaks. I.

B

A

That hears what it needs, and otherwise, if that's not possible, you can use the str method, and these are just a few possibilities that advises, you will probably see it in raesfeld, 5 and others. It really is that there are a lot of ways.

B

A

B

Ideas that I would recommend you to start with.

A

Just use the that actually covers almost all cases.

C

Sometimes it is.

A

Semantically, correct that you would like to write him. There makes the tiled are more, but I wanted so you can use inner to spring first. But, inter is what.

C

Most people use do.

A

Because it works, but well that just becomes a newspaper with experience from a few typical hobbies. For me errors, especially with unicode number one indexing has already told me, is problematic. You might want.

D

To expect something like.

A

That so that something like that would work stringer and now you want the first letter can be the first character. What do.

B

A

To come back so it's.

B

A

Should look at probably that.

B

As of today, the pages.

A

Don't have systematic characters, but the problem is that we just store that store and have a variable regime.

B

A

Means we can't.

B

D

To an essay so.

A

The destruction card.

D

Character say whether.

A

What contribution that is, we have to through the whole string and always look okay, okay,.

B

A

There and so on that.

C

Means it's an open operation.

A

C

A

Initiation does n't work at all. That's actually always wrong. Instead, what I just said is important. You do it completely under everything that should be told, and you have.

C

A

Back to this coding thing again and look for these different fonts, it's pretty clear to us now they're two characters, but it's not always that easy. There 's, for example, the user festival character in june, short standard. That's how the name.

C

A

Is somehow a character that the user recognizes as such a, but that depends on the language. That means some ostrings would be less correct for some cultures.

A

Several plots: it is absolutely unclear what a character is. There called him clusters the clusters, several short next to each other. No other way will be free. There is, for example, do you think food is coming h&k web-based june by standard will also be so important that there is a dashed price that the landlord then somehow puts an addition like, for example, the oil points. That is, a code planned in june from standard, and we can now show her in front of a pro strip.

A

So now it's in memory, both don't know it and the rendering engine has to take care of it now and looks okay. Now, that's a conspiracy character. That means me come pier and get out.

A

That means a feeling: cluster will now both want to defend a goal, point back up and contain these controls character, as described cluster clustered, the first boyfriend and everything of women characters together. Yes, maybe once.

B

A

Internet so weird creepy font, the so completely degenerate falling in love, have signs so that a lot of funny things need fodder. Had you seen.

B

A

B

That, in which you attach a super large number.

C

A

These coupons from this character and then you.

C

A

Of endlessly stack upwards and quotas like you would like. That is why, if you copy such a text is also relatively large for the number of user passive characters, because just so many compound correct centers is completely unclear. What you want to see. You somehow have to say goodbye to this belief that you can change certain characters string in target rank as former that doesn't.

B

Make much sense.

A

There is a method for that. It means that the theater back, which you can also prescribe italy with a so you can say before ca,.

A

Further, it goes and then you can now use this method, and so there are.

A

Two daughters at the ends along the way back in this case.

C

But that's now.

A

Integrated via the coupons, that means.

B

C

B

C

Any clusters you.

B

C

Think of something.

A

Else so it's a bit.

B

A

Complicated by the way, there are also other methods somewhere, where you can also establish clusters via copies is not very easy and two the length here. You would expect that. So, if you take the length of these here now, you would expect maybe two, but the longer is simply defined as it pays here. You.

B

A

Think again, what does it actually do me in the larger context, longer.

B

A

Finally, brings me nothing because nobody knows funny user passive character are. That means the only thing that brings me the number of bars that I have to play to get the stream over copying or something else that makes sense,, but all other lengths don't really make sense, because there are just so many different interpretations of the perfect and even.

C

If you just want.

A

To make yourself, for example, somehow don't know how to go to bed.

C

D

To know how long.

A

It is the string on the screen. You can't do that with a length of about that's just, not possible. That would.

B

Be true, it would be nice if.

A

It were that easy, but you always have.

B

To talk to the rendering engine.

A

And say he draws this drink. How long was he born now? Can't that just be the cells of carrick? That, whatever is a character, is nevertheless prompted in the correct scene, just count on these employees. Now you have the chance again. You almost never need that because it doesn't really make sense.

A

The two of them aren't perfect either, knowing that it's about coupons, and if you want to somehow deal with any text, then you should think of something else, and the last one is one more tick capitalized.

A

There is so case here to form electric parties, then some other weird guy would come back. Would you now expect? But what do you actually expect to expect interested? So look at ssp kits? What is that?

A

No one can do it somehow or first names.

C

Club chairman.

A

Exactly this again, this commemoration and money, we can now just make a character taker, the truck race, another character. Unfortunately, my luck in german. It creates it, and that applies to many ligatures design, typography term. That is almost a combination of.

C

A

Characters that you often find at s&p,, for example, the alone, but dangerously beautiful font, then has the dancing between the panes of a canister. It looks like that, suddenly, a character you see,.

B

For example,, if your body leaf.

A

Is very happy to do that is such creatures created.

C

A

Will also be a unicode character again and under create. It also came from his lega tour, namely the connection of a character sz, the name. Yes, that came about over time, and it actually looks like that. The congo is out and if.

B

A

Buy this sign also a junior partner. You will capitalize on that again. The big sap is positive.

C

It's not always that easy.

A

Okay, what gives says elisabeth otto s k s, that's a bit of the processes tode, but that maybe doesn't make sense the comments. Only all the coupons, the mask area.

B

Are the apa kabar values , because there aren't such problems as there.

C

A

For example, area spend.

C

B

A

And that's hardly quite easy on facebook, but.

B

A

Ignore everyone else, then you can think about it. If I now have a web application- and I want to meet all over the world at some point and I can somehow enter your name, I would like to enter the first letter but capitalized. It is more difficult that I'm thinking about what I'm.

B

No longer sure of,.

A

Probably in many languages, this concept of capitalization, I, like someone again,, that we have a favor there, for example, Japanese, for example, or some kind of Asian font,. Is there a large drawing mark,, then I thought.

C

A

Something, okay,.

C

A

Different cultures, we can't always adapt to our system. Well, so now we want to say unicode the complicated objection it's complicated unicode just reflects some language. Language is extremely complicated, but unicode reflects that very well, and unfortunately, this makes it complicated in any case,.

A

Well then, the last.

B

C

A

This topic is indeed you can get to know all this, that we have just learned in general, and that is if the system, as a free service provider got to know each other, but we also know that there is this quiet de again at the beginning, have already got to know this comparable with str. It is important that these two data stores are exactly the same and c programmers will say why then do two types have the store at the same time.

A

This is this concept of strong typing from a strong type system which we no longer just describe with types store on, but with types also receive semantic information. Write sdr has this semantic, are information in this memory, and it is correct that you will notice over the whole system again and again that some things are indeed the same memory but other form other semantic information. Both are also called hot types. Well,.

C

A

Means you can't do very much with this guy here alone. That's why you always see it only with one and before that, and also a reference to this service provider has the length what 's just ripe now I know what I'm the and virgin from so before this price. That will give you a nice eye, so the conscience.

B

First, the version that.

A

Has the weapon is capitalized and where can we then see this left performance.

A

So, first of all, what we already know that I have done before I, very briefly from airways we can select such things places the airways that we have always written a constant longer. These airways are also literate and also sit in exit to direct. That means that.

B

A

Approximately to the string middle rhine, but otherwise the most used is this way or the world actually pronounced vector. This is a data structure that we will get to know in more detail later, but this is the main data structure to store frequency data, so something like building a list in the year is there now says mainly from government, but there are many other types, for example raps and jena a little hint.

A

We want functional arguments because we never want to hand over this and increased sound or and vector, but always only this other version here must, of course before. Why is that? So you want to call each other.

E

B

E

Would have to yes because he, this time to my contract with in this case, we probably have to copy then hand over.

A

B

Since we drink a.

A

Reference interest is, and I see that some air.

A

Then you can not change and then.

H

Delete create, it only has a youtube.

A

E

We had another intervention, he exactly.

A

That this is the exactly. Those are the two reasons that I just warned you here. We have to talk to the officers twice and we have the problem that, with this.

C

Expression we already.

B

A

It has a string, it's a keeper lukas trinkers, that's just the generalization that includes several types,, especially sources of springs. If you would accept something like that, we can't put in intervals. Dandys penetrates he's all such types. That means if we actually wrote such a function and we wanted to give a string middle rhine. We first have to copy the string metal on the block and then forget about it again. That would be very, very cumbersome. So it's.

B

Just that it includes.

A

Several types that is, and especially with the slice it's much more extreme, we can accept such a vector, but then we really expect that this source of the data is a vector stored the tender. Instead, however, this is given over and then the calls outside ban. This data can be fed whether it has a static array or vector or any other strange things. It's just more data, more types that are possible and that's why it's still okay, here persuading this with youtube.

E

Exactly to change.

A

Something you have to have more information about it. If, for example, I want to push something on a hectare. Then I can I do n't just hand over the read.

C

A

Bit of a hint, we should do it ourselves and, in particular, also a link to a place where questions where that's explained again now about this whole topic. Strings still ask.

A

Exactly that's also a thing that you first learns a bit with experience, but you always have to think to yourself: do I want to own the string, buyer right now or not, and if I say I don’t need to own it, then I have to know that it will live as long as I want to use it. Then you.

C

A

Thoughts, how long does it actually live now? There is an example for that. If I have some function, that I do, n't know that tents a certain number of characters in a string or something like that, then I would of course use these read strings because I just look at them and I don't have to change it in any way and I don't have to own it either,. But if I read strings from the later.

G

A

Definitely then in any case,. That's mainly why it's easier, because you can say I want to change, then definitely somehow capitalized and can then change string. If I, in this area, we need a lifter noted dad thats, I think you easy to breathe, saying that and yet another example. If now dont have functions.

A

Example: 1 what get the middle east back in the name? But what exactly? What will.

D

C

A

Okay, but that's how the name always lives remember or have.

D

A

We have to be aware: it's somewhere else.

D

A

The function, but how does the function come about so.

B

A

That means somehow, in this function, with the name created or.

C

A

Even better, that's.

C

A

Stupid example against the online game right and random names, for the characters have somewhere around how to name king, that a real algorithm that somehow, according to some rules, roughly.

C

A

It generates that's quite interesting. It's going to.

C

Be in there generates a random drink.

A

What is there now back.

A

D

Drink, why quite nicely that.

A

We testify here in string with any changes if he would return his reference to it. That starts with peter deleted after drawn so it's over. That means.

B

A

Put the signature in the Possession of this procedure is sufficient so that the caller then owns the function,. So that is.

A

Definitely necessary in this case. You could do it here, lukas randomly.

B

Decided who was to blame.

A

As a bad example, because here a.

B

A

Should be generated what I just won, then it does n't work again, because I somehow do something dynamic and dynamic means. I have a water that doesn't stick in the data. That means I don't then somehow refer to it then ask it will become clear in time. You need experience otherwise ask about the story.

A

Ok country, our next topic, unfortunately again not because I think it makes sense if we delve a little further, even if I would also rather do something, don't worry, but I think it makes sense that we delve a little further so that you understand a few other things. Yes, I maybe didn't quite understand here. Maybe a term I suppose have already got to know yes, not like in eye.

A

You may remember there is another note built into this network of posse tories, titles or another, for example, a remote, the original rigged up immediately thawed and self-defense on a local copy on a notebook. We are just this clown.

B

A

Who are buses by far the.

C

A

The first time can also, for example, to list from enter slightly curved, then with origin. That's after all the report, that's there from the start when we master, so it's not always there from the start, but if you clone from somewhere that he mostly does. If he has something on the top, then it is always there from the beginning. If you say so, an empty summit happens just like that created austria created no mother, because we can. There is information when calling it up, then I will be shown it.

A

What kind of usn is behind it? Because now the urls are so a note is identified by this url. That clearly says where this place is, for example, this.

C

Says: stop hey that.

A

Is now gotten surfaced and under this path these took the we always used for this shortly, for we can use the url everywhere roman. We can also just post it first, of course I don't want that, of course, always from 10 years, for it a typical name of monsanto ritschel, it's created automatically, that's where hermann originally comes from, where they explained that it was worth. It has upstream, quite often for the super story.

A

So the original first operation designates your site on guitar, and you have upstream that then designates my story, so the original worker command is there is, for example, just create this pair of names url in front. If you use the names and the ul or you can simply have the delete at the back or you can also turn it around.

A

B

Are different oldest that.

A

Goes to different cards, there are the https types that you had already seen: the clown. Can there the web http and it does this ss hair type, give the ssh url, because children have ssh and you may have cloned wrong sometimes, and do you have this https or you whenever you want to know.

C

A

Tapped submissions that happens when you use that when you need this, ssh url need this ssh key that hopefully many of you have set up. That is just a lot more convenient and then you can activate mss in football,, funnily enough,. There.

B

Are others, for example,.

C

A

F

A

For example, local url, that means, if you have two folders than if you have a post,, for example, 204 and you can just say a remote look under your own files. Folder xs is also that means I can communicate with it in the same way as with any server of the oslo, it is really nice for general. That's exactly where I want to show you, because you always want to go back to poland without a subject. At some point.

A

Schlager will have changes again at some point from the original repository,, especially large projects, workers, for example. Suppose he wanted to work a rast compiler. Then you follow this oskamp one on github changes something and found everything nice and somehow a week later wanted to work on it again or a year later, but not on your fund,. All the changes from all the other people didn't automatically come in,. That means you want to get the other high changes at some point,.

A

That's why he wanted this one from add: let's see how it works, that's our well-known 4 test! So now we want to clone it. So click on it here, as I said I'm using the https.

C

A

Here now, but you can use the ssh I just have for test here, can shk set up.

A

Like a posse, tory cloned and if now fit for fashion, then this origin has already been created because we let it be shown more precisely. You see, that is the exact url that I gave up here when cloning and now want. We add this upstream,. That means we go to it because it is missing, and now we go here on forefront and we copy ourselves into this url, and now we say in the upstream name that and the url I have that big enough.

B

Then say it again:.

A

A

Then see we are here now: ok, both are registered and once here is the protest in the name and once lukas fleet, but he saw that it was going quickly now he has not yet done with the network. So what did that? First? Add the 10 not worried at all good like that far so good, you have to go back there now, just look that you are remotely playing the violist, and that is the next term to watch the whole thing and.

B

Although we know it will surprise you.

A

B

A

Attractive the plan should be displayed in this case handle your master plan are also currently on the master plan, because we.

C

A

It out we are branch locations, then it is displayed because all browsers are displayed, including this plan of the coach someone. This.

C

A

Rochat or master, sometimes the remote is also omitted, beginning in any case somehow there inside the fashion decoration in this case and then / the industry are so-called remote place. Is this different to local porsches, local industry.

B

Are the ones who have the normal poor and.

A

In the place, not brothers plans scheffelt the place, namely simply here. The last position of the industry was the last time we communicated with this server. So, of course it doesn't stay on the internet all the time and keeps checking and updating from the server. No, you have to explicitly push these remote brothers are just there when we last pushed so the last time. Holman from the server said everything here then it’s just bad luck. If we have, for example, and his carla master plan is on it here, but the emergency plan, I.e.

A

the remote touch and two other customers, are sent then it’s, for example the daad, and that 's only meant locally,. That means we've already updated and somehow gotten x data at the time when 2 0 was defeated here and by the way,. The fed is also explicitly shown.

C

A

Goes and then we go to in need, for example, fetsch origin goes the compact design award and updates the branches and loads all the comics mother to complete the history of the missing totals. This is our local pc, and this is the regent, remote sosas, probably from in front of the picture on the slide, and now the local fetsch origin is being executed.

A

That means first- and you are here, the lounges are just pointers are being created, but you can see that it is not enough, so this back up plan is shown in order on a committee of the location, but we still.

C

Have to download all the commercials.

A

That we also need to complete the history. Are then the two of them work.

C

So far everything works like land all garages point to proper.

A

Coming as far as clear.

A

We could actually have that again now. I already said, I haven't contacted the server yet I just added this url as a name. That means the industry doesn't do things correctly. The origin things are displayed, I found the hall I've already contacted it, I planned, but the upstream things are not displayed,. That means, if I, do it upstream, now, well,, that's exactly.

A

How it happened? Now, I've contacted the server, I'm going to branch again, but then I also have upstream latte now,. That means I have now looked how it is, but turn off now has no new comics. It looks like.

A

I'm not sure, but I think abzuegen doesn't have a commissioner, but otherwise something like.

D

That happens will happen.

A

Soon so you haven't heard it for the.

H

First time exactly right.

A

That's the knowledge of the master magazine is now in view of it,. Our local plan has not changed at all,. That means, if your normal.

B

Local ones would continue to.

A

Work,, nothing will change.

A

I generated it at the beginning and.

F

B

F

A

You can do that with word internet plans. The merge this plan agrees. There are merching in the current wheel tires. Now. You first think of something like that. It is now a situation where the histories the histories have diverged. That means it's always as nice as before, where we, where we had everything in a.

B

Row and only one of the two.

A

Added, but in this case, if the histories that react, because now there are plans to execute or to be on the safe side, checked again master so that we really are on master, then we say we are going mary, jane foster,. The origin master is now mixed into ours, and what happens is that a new one comes,, although a special one is created with it being so-called debt management.

C

A

Two fathers or two predecessors, and what happened to others, is that there is a master is set further because we put the upstream master in our master alone. It's okay, what's happening now,.

C

B

A

Example, that's important now that you understand that if we do the same thing here, then it only happens that only these pointers.

B

A

Bent over by our local brand I almost set forward fast forward whenever only one of two Germans or something like that has been expanded and the other can simply be placed against the fire on the new comic. That's important because you often want this phase forward. Burgess shows that again, with this great one website.

A

It's small again, I'm sorry, but this website, as I said, try the whole thing again.

A

Maybe it's ok, so they've already seen it now say it's easy to do with it and if you say now, for example, glasses are brunch and don't know, places landshut. We have n't pronounced it here. Yet that means joining in the disco there I'll put master on there. We can check that out again and we can.

B

A

For a sponsor here too, then we already have a dividend: history, that's what we want,, for example, master in drove a fairy tale we're already there. That means we can simply say that goes, merge master, and now this new comic has been created. That is, a person to person with two ancestors was continued.

A

Ok, now we do nine branches again and now just continued.

A

And now you almost want that. Try it out on site,, we now have to change cash from tekken,, so we have to quickly change the previous ones and then say albert and either we are now conducting. Then it will be created, or in this case it is so that everything is nicely connected that when the execution says it will just continue. Even this tool is displayed fast forward.

A

That doesn't really make me, let it be evaluated, that's all so you had you told me and instead of being master in food, we were human and we were as ffu in master fairy tale says. Yes, the plan came across already up-to-date because masters simply up-to-date. As for that means to has no new information at all, we always want to shout out the plan mortar to us that has more information than we have in any case.

A

Somehow the idealized variant of what's happening.

C

A

But it becomes quite problematic to so- called merge strong and it can sometimes happen like this then looks hectic written conflict if you notice- and that happens, if you somehow let the same files edit each other. So if you edit different files, we are talking about the case that the street acts fast forward, always conflict-free. So if we have different comics and the last message before and in these communities edited different files, no problem: can you edit the.

B

A

File, it also works quite well in there, but of course, if I edit, a line.

B

A

There is no chance at all alive to see which one should be used last, sometimes maybe an example, but it looks like this after this message came that there was a conflict in this file. Writes just goes to your files, then it looks like this.

C

A

Then he says so funny thick dedicate. That means just works. He writes in there so that you so that we have to see what is right about it. In this case, 2 comments were created where a hello peter, therefore a hello, anna wrote. There is, of course not able to decide what is the right thing and to take both is also possible, not necessarily correct.

A

That's why we have to decide now and then it will be displayed as well, and we can simply delete these lines out of the text editor as normal and create them again differently, so that in valid / program we don't.

B

Need anything special to.

A

Give here we just have to the fixed again valid the program if it benefits again as well, that my name is removed where it says that 's, what we just unpacked so.

B

A

Most cases and what he's subordinate to that's, what we just purely german want master. For example, if we.

C

A

Raised this conflict simply by editing the file say there is better and then it will be displayed. Your lawyer prof then here is what is currently in word, namely this file. This is now an additional file status. The file can have that iranian notes is declared as soon as a.

B

A

To a conflict, we are in a swabian stage, so to speak. We now have to resolve the conflict and then finish it in word. That means you shouldn't, leave the computer in this case now, but to complete the afterlife such an insecure states, insecure stage that we didn't want to stay long and then you can follow the smartrac package and the file that goes with.

A

It says you pack it and the stage terry means in this case I have conflicts, you should you can do that now, take it straight away and then just say funny about this merge conventional. If we don't have time and the markets first, you can simply enter that you, so to speak,. That means this gives a merge command is simply reversed. What if you had never given it, that can sometimes make sense.

A

I would show that again.

A

So we can now create a repository here and say about hello. Rs I just feel the same way as before. So at the beginning, there is the hello world, wonderful feeling that you added wonderful.

B

A

Funny one saved in our posse tory nice: let's create a brunch as peter, and the job branch means others. First we want to go to wiener, platz and say and edit the file now and can say peter is the world and then tell me, go to usa to send it here. We see changes again to three committed. We have just changed. It later would like to say, checked anna accept what is there now in the file quiz question.

B

A

Exactly right have gone back to one, and anna still has the status of masters alike. One is close alike, I hope comments confidently,.

A

Now we have three comics,, but the conductors,, so we no longer have a linear history,, but the government,. If anyone comes up with the idea, or let's say in the master plan,, it should all be managed now and now says to example, man that does first, I want what I wear im virgin now it is here on site, because I hope you can all imagine that in your head will be massa so think about the master.

A

We showed another one there, but if we now somehow that everyone wants in master, then it just goes on is just a reference update, but now the whole problem, if we say goes peter, then we have now edited the same file twice and in particular edited the same line twice that can't decide. That means yes, with the merger of my editor poker. That's exactly what happened and now that's a stupid example, because there is no right and wrong here and now you can somehow go in march, so either.

C

A

Can how you're really funny you can go to example,, just don't let them be shared and say both should stay. That might be fair or you can decide something.

D

A

A

That's not a problem. Different content is not a problem if the.

C

New content is.

A

Better, a new content is.

A

Displayed and will now be in all.

B

A

A

And as I said, whether there are changes, it does n't matter so long ago that there is only one new.

B

A

As long as there is only a new history of changes, there is a a set of changes. Then not all in this place. That's clear: it's not a problem. We can fast forward soon. There will be two sets of changes, then they have to somehow.

G

Club exactly that power.

A

There, otherwise always than its markets, convinced I can- that is not fast.

B

A

B

A

Match I feel that you have to change then I will show that again briefly, maybe, but not even with the time. Yes, I think I have to react in any case now I can say something nice and then it says really. Okay, that is.

C

A

Ailing the city says hello, there is no sympathy and if you merge by the way, you will always asked to enter a cow with a message, but merge completely already contains an automatic commit message and you can actually always leave it in there. That's fine. Unless he has really made a very complicated one, then you are welcome to describe what you have changed. For example, you can say here: okay, I have now adopted both names because the statutes have led to a conflict, and it is not entirely clear what happens if it is conflict-free.

A

It could actually always leave this automatic message in there. So I leave the message in there and now I have I created a workshop with that means again.

A

That, then, so far clear.

A

Ok, I can't show it anymore, unfortunately, but we want.

B

A

To automatically arise and no conflicts want to arise immediately says there is a message with.

C

A

Message editor I've already.

C

A

As well a word of warning, you have to be careful with the parents, because many use the parachute to start a match com.

A

Ultimately, not a very nice result for him, so you need them again and again, but you want to get away from it as little as possible and painted a little ahead of the owner and offered the states themselves at some point and everyone provided their property with some, and I would like to somehow pop the changes from everyone, because somehow all the changes are woke up and continue working now there is a margin could because the weather is conducting the stories. And now we look forward to repeated created after management comes and bob decision.

A

I want to have too says in egypt: there will be a lot of match. Comics the parents will only be very unnecessary and that ends up in something like here, his screenshot github. In a project you see it.

B

A

B

A

Pointing up and down on a small knob, these buttons are the kids times, so not all of them are always explicitly drawn here, but, for example, this orange line means it is a plan and the holidays are back. So this committee.

C

Has a father this.

A

One, your father, doesn’t.

C

A

Fathers here are so the.

C

A

Match is now another case on it shows, and that is all over the place that is not particularly nice anymore has no nicer history. There would like to maintain his tested, so you should avoid.

B

Something like that and should always be aware.

A

Of what and when a merger occurs with dropbox and again it doesn't work, even if you would like to use it like that at the beginning, it really doesn't work with dropbox and always market it. Just because you want the changes is not how you should and can do it.

C

A

With a pool where one gives the arguments, remote and industry is basically equivalent to going and david byrd remote degrees. Well, this here saw this fashion, brunch, that is here, and cash is from what is on top of the real need that I just want, because I do that, just in a short cut and thus get this job, these dangers that will also come a reproach in which.

B

Several things can happen automatically.

A

You just do things well, so there are, for example, people who think afterwards you can save the job. Could they updates? No, you really have to be aware, and that also applies to commissioner, what it does it's, not a problem, because you use such simple commands as long as you always know what they are doing, and you should look again at what happens then, e.g. always works fully, and every time there is a match like this complete. You have to think twice. If I really want to.

A

Do it all over poland- and I want to do it differently at some point that then a powder than almost all my end, and you.

B

Always had to be aware of.

A

Something like that by the way,. I also have to see in the sense of tutorials that there are more files in it. I ca.

B

A

Explain myself so you make massive and or strengthen.

A

B

Do it, of course, if you.

A

Know what it does it's.

B

Just all files, but.

A

You should always take a careful look at what's really going on,, for example,.

B

In the message.

A

Editor, you can always see what's happening and which files are being added,, and if it's an exe file, then you won't get any messages from the editor again enter, go out and do the fix again so always check what you're really doing. Don't just do points again somehow works already, but then flowers were pushed up, for example,, then I think there are only two slides left it creates for me shows again now this trekking bike is that now has another kind of nonsense.

A

So it's not really but such commands as the pool and go pushman all wise. You call them up with arguments. You probably didn't do them all, but normally whether you use them with arguments on which remote do a lot of research and introduce yourself to which branch in this area so down. If we always give the arguments, it might be a bit annoying. That's.

B

Why you can set up so-called tracking.

A

Brunches to work, that's how the man goes, brunch says cow, and then you give it dirty plans. The remote branch, for example,. If I'm joining at a brunch- and I want to say he's supposed to scare the remote broadfoot, then I'll say that that means just for tie the sympathetic goes. They are somehow semantically connected.

A

That means, if you also like that a brunch is it set up as a tracking place one remote place, then you can call it up without arguments, for example, and then, for example, said: ok, boss, your brunch is somehow 3com it in front of the other edge. So such information, you just keep going white. Okay, are connected, jan doing that with each other get this.

C

A

Give bush if there isn't one do n't you tell a few of. You saw that she had problems that kinda so wanted to say pushed. But then it says I don't know where to push or whatever and then maybe he'll come up with the solution, specifically, it's about the Swabian plan, we could just go through and then we took origin and brunch,. We set it up automatically,. That means, and this tracking is reported automatically,. It makes a lot.

B

A

You can do that,.

G

Yes, I want that.

A

Not yet pushed live last slide to that you have already used that, but what does that actually do exactly there? You can also went wrong. I think you didn't see it, but you can be that the project will be the plaster, because the push north so pushed will come from an update.

A

That means is posco almost whether you can do an almost finished work, if not through that from that means, then somehow the server will come now that you do n't have yet you can't push it to the server first, have to get it completely down and then somehow remember with you and then you can push then I know fast forward.

A

That's the right thing to do and you can also simply state the arguments explicitly but I think with chicken brunches. You can come up with a lot of questions about.

A

What other certificates you have since I'm curious how everything is going, I published the exercises, yesterday, I, don't know,, but I'll, take a look,. I can always do it on time, I hope that the exercises are still not too difficult,.

A

Once that's not passed, 1 rule, water.

F

Wagon that.

H

A

Also briefly announced apps, the Monday reader is still included, so it's.

B

A

From Wednesday you don't have to know, but from the Monday reader, it's about your ring. That's already being asked this week.
