Introduction C++ || 11th CS || Chapter 3 #computerscience @a2zpractical991

All the tools and resources you need are conveniently located in one single place. Such platforms are called IDEs. It doesn't make sense after doing it. I mean, things like 0101 are present here which is in human-readable format, in machine-readable format Only a machine can understand him. So, we say "object" to it. What compiler do you need to keep? It takes everything from whoever does the source. And converts it into what? Converts into machine language Hello, how are you all? You will all be great, you will all be wonderful. My name is Rahul Singh. From today, we are in class 11 Third chapter of computer science Introduction to C++ Let's start right here, okay? This C++ is ours from Maharashtra If inside the board you are with anyone else From the board, and where you people are This is the C++ chapter, so You can also watch this video Don't waste time without moving forward In the lecture, we further examine how we perceive things How should I read it properly? So, let me see What is written in the introduction about C++ is here in English What I write, I do what I do But the man, what is his name? What is called missing inside what was previously C Programming? The concept of Object-Oriented Programming did not exist within the C language. So in 1979, the B&A Stroke Staff added some extensions inside C. They introduced concepts such as Object-Oriented Programming. They introduced even more functionality inside C++. So initially we used to call it C with Class. Alright, and why did C++ become so famous? Because concepts such as Object-Oriented Programming were introduced inside it Which we will study in our Class 12, okay Just remember this: if anyone asks you if C++ was first developed by some person You should remember the name of Birni Stryo East, right? Actually, it doesn't have any significance; I don't even remember the name. It's fine if you guys ask about the history of certain things. But if you happen to remember the things, it would be even better. So first put C++ inside Bell Leveler's. Inisseli called it the Cevit Class. After that, its name kept changing with every new feature added So, started speaking in C++ correctly, okay So let's move on to our next slide and take a look. Alright, instrument development, instrument, alright You must have heard of the name "Sori Integat ID," just as you have We are the Scud Sonna, which belongs to Macrosop, correct? Intellia, then Delik Edit, then these blocks, so many like this ID, check the ID, what's the point of creating an ID? So that your efficiency increases, your productivity increases. For example, suppose I'm developing some sort of software, right? I'll also be using Java there, right? And I'll be using Java It also feels like it's coming through, and whenever any language seems to be appearing, what should I do? I could go to different platforms and write each feature in the respective programming language, then add them one by one. That would be better than having someone else do it. Perkara is a text editor where we write code, right? But along with coding, it also provides all the necessary resources required for developing that software. It even makes available all the tools needed for development, all in one place. Right? So, that's it. Because it provides all the tools and resources needed to develop SopTved in one place, it saves time. Exactly, the time consumed is reduced. Productivity increases, efficiency improves, and we become more effective because we no longer need to handle tasks separately across different platforms—we get everything in one place. Okay, so there are many IDEs listed here that you can see. II What is this? This is a boring guy. When you want to do something with Rohan If you want to get work done, what should I say to make them sell the leftover rice? What is needed is an affidavit stating that whatever work is being done will increase the loan amount of Yans Loan. Rohan's father says to Rohan, "Bring me a glass of water." So, Rohan's mother had already drunk a glass of water before. I mean, just bring a glass of water; its memory is already pre-set. Then, when they say something, Rohan's mind will process certain things. After processing, you will understand the things. After understanding it, wherever water is kept What is a program that, for the purpose of executing a specific task of an imaginary machine, is being prepared and gradually developed? As long as we don't talk about things beyond basics, it's fine to talk about whatever basic things there are. Because it's a concept far ahead, whatever we are doing—whether B.Sc., B.Tech, or similar— There, they'll also learn how to multitask and multi-program more effectively, right? So Rohan's dad also gave him this task—what was the task? It was to get Rohan a glass of water—just like a computer system. Son, it's very Rohan, if you're feeling thirsty, drink some water. But still, what have you been looking at? She said, "Inside, I could have become furious." We have already sent the Hindi, Gujarati, Marathi versions to them. If Maharashtra, then speak Marathi to your children, as that is their language. Sorry, I don't know Marathi. Well, actually, the one who is their father speaks Marathi when asking his children to bring glasses of water. If you were Gujarati, you'd speak in Gujarati; then what would language be? Language would be nothing but a mere nothing. Mod up communication is fine, that we express our feelings and whatever thoughts we have, that's fine. If our bank is coming, then the time for the alarm has arrived, the blood-red button must be pressed. Those who speak in the gutter, they spit water at their son. It's fine to bring it, and if there's anything else, it's okay too. A single drop to the ocean... Baipe Faculty Channel is the best! The moment the light touched the surface… To carry out the task Alright Both of them are appearing here. source code and object code Alright We understand what source code and object code are. What is source code? source code Things like this have meaning. I mean, this is the kind of setup instruction it is which is in human-readable form Alright, as you wish When we study C++ then in it h include It will be written in IO stream, correct? Then it will be written here using namespace Okay I write in a messy, scattered way. Then it will have written int main And here is where It will have curly brackets like this Alright It will be written here It is a mess. May fall include What things will we understand? But I will write it here. So that one Set instruction What are they called when they are in human-readable format? And when you come from the search, go ahead to the left of the door, sir, through the passage, BB, just follow the path, and then turn left at the stairs. Dziękuję. Surprisingly, it was So when we provide our setup instructions in our human-readable format So he would go inside the computer system and convert things into 01 format. So, in the format of Jiro Uo, you're saying things that are your rent. Vandhi for this examination is being held at the venue. It is being indicated here that you people are being taken directly from your family into the shelter. I mean, you understand why things are written this way because they're written in the English language. You can read these things, but reading 010110 won't make any sense to you. So meet me when you can read or have read the dakkar's pegar Read something on the face, then read for your own sake, for surely the meeting with the immortal is imminent. Let's take Rohan as an example. Here is Rohan, and Rohan has gone to Amedica. There he met a boy named Sohan. But Rohan only knows Hindi, what about Thikké? Only Hindi comes to me, and only English comes to Sohan, okay now Rohan has not been able to understand his words up to this point, and he has not been able to understand his words up to this point. If I send her a message, Mother, why should this happen? These two will surely quarrel. They can interact with each other just like users do. And provide the reply converted into our language. So that we also understand those things, okay, so what is a translator? It is a program translator; what is a program? It is data. translates source code into object code I'm just now at the previous slide, you People are told what source code is and what object code is, that's correct. Vas Lembéz Co And and that program with d You're trying to explain it The compiler is Prince Hair They are also typed very carefully. Look, here are the types of Translator given here Compiler is, Interpreter is, then comes Assembler. Okay, what is this? Type of translator Okay, I hope you all have understood. Look, here this Language is This is some Coder who is coding Why? Because Computer System Which languages does it understand? Binary Language understands which is 0 and 1 0, 1 can be treated just like a switch. When we turn on the Switch Then we will represent it as 1 from it. If we turn it off from him We'll represent you from 0, right? So, even during the rainy season, time passes by What is a compiler? What is an interpreter? And what is an assembler? Before that, let's understand a few things. Okay? Then we will come here and understand the things. This is our first program. Which is given in C++ Right? And what about you people in the ant? What is this? This is the very program Dhaw Program is going to be executed Alright, we'll understand it Okay? And this is C out. What does it do? Computer... look, C out and angular brackets Inside double quotes What does it do? It works for printing. print to screen When the screen was boring I am computer I'm talking about the screen. Okay? And what does return 0 indicate? that our program terminated Whenever you write return 0 So the program should be terminated Okay? Look here OK? Whenever you What is this? C++ The first program syntax is This one is for you You should surely remember Okay? This is a basic structure. of C++ Okay? With whose help You will do coding. Okay? So your things OK? But When you write this program Hach included Hey, Estee Int Me Then inside it Steady Double colon C Out Then hello world Then Riten Zero So what will happen? You understand Look here OK? Now what does this mean We people After that Understand When you This program In this manner Write it down Okay? You will run. So the program First, there must be a battle. It starts The man function starts from What does this do? This computed screen page Whatever it may be Tako What happens? C Out You will write. And this Angler bracket and inside this double quotation Say anything OK? Whatever you write What will he do? Now you will speak What is an operating system? Look, here are the things It cannot be told even in great detail. Because the operating system Class 12 First Chapter There, we people talk about operating systems But I'll give you all a basic idea. that there is a user And there is a computer screen Okay? The user wants to interact with the computer. But which language does the user speak? The user comes. Whatever is from our English It comes naturally. What language does a computer understand? Binary language comes now, okay? How will the interaction between the computer and the user take place? Interaction takes place with the help of the operating system Converts its language into this for it R Graphic illustrates the interaction of things with which the computer and the user interact with each other Can get arrested So the operating system that exists The operating system acts as a type of interface. What does the Interface do? Alright So What should I tell you all? As you will compile the program Where does the compilation process start? As it is started from the Main Program But this code runs, updating the system runs Because Iostream is a type of header file Inside the header file, a lot of functionality is written in the form of code. It is written in the code of codes. Discourses of this kind are needed. Who performs the work of resource and label assignment? carries out Hear the inclusion Who uses the Hach? What do you call the person who includes? All headers included The file is for including them It is used Whenever you write in the chat So whatever functionality there is Your program run starts from there. which your compiler runs C++-based language We will understand what a compiler is. They will also understand all these things. But I am trying to explain to you all if the structure of the program is known So I'm telling you all When compiler, interpreter, and then assembler If I explain it, you all will understand the things even better in a much clearer way. If you understand, then I hope you all I will explain what I want to convey. I mean, this is the main program Because as you do in any text editor I mean, VS Code If you run the things, they should compile. So, I keep doing compilation from the main program. But the things above it don't run either. Who will process this? Who will process this? Who performs the task of the operating system? Why why because inside it Iostream There are many header files inside. There is a lot of functionality written inside the header file, such as If the program is written using cout, cin, then these Don't programs also need resources? Who performs the task of providing those items and labeling them? operating system does I mean all the processor directives there are Who is responsible for running it? It's the operating system, okay, then Where will your main program be compiled from? It will start from here, whatever it may be functionality is cout, what does cout do? Whatever is written inside double quotes It works by printing onto the skin, showing the result directly on the skin, okay? And what does return 0 indicate? that my program is from here will be terminated Because we are not returning anything at all return 0 These things here Inside the parentheses, we Passing the argument, okay Argument and this return Things like these We will study our function in this chapter, okay? So just keep that in mind, my friend Why are you writing return 0 Passing the argument, okay Whenever we Classes will be held, okay? Whenever we use standard functions Which got c out, became indel Alright, if c has been done, then we... What will he write and read again and again with him? std::double colon Why, because we people are c out What kind of class is this c out? Whenever we have class Alright, so what do we have to keep writing over and over again? std::double colon c out Okay, if we have c is to be written, what does c do, user It handles the task of taking input, okay? Now we people based on input when Alright, now understand here Because c in what, c in also is a kind of class Then whenever I use him too Alright, so let me std::colon colon will be read as such I want to have my In the program, std keeps repeating these things Write, read, okay, so what will we do? We will use another pre-processor directive Alright, that one What is a pre-processor directive, using namespace What is this using, you people's using pre-processor directive is, and running it Who performs the work, run it Who will do the work, our operating system does it, okay, and namespace Do not write this repeatedly, in full The entire program is written, correct, okay, its if functionality is written, then look, when I used namespace std; then From here, std Double colon, it has disappeared, What happened? It's gone missing, Alright, so I want my program to I keep saying std Double colon, no need to write it We will have to use it for this. using namespace standard, OK, I hope you all understood this program It will be, what does this program say Chinkulud Ayo Steam, What is Chinkulud, the pre-processor for Parcar? Dart, I/O, Steam, what is I/O, what does Steam do? Because I want to say Hello World, It appeared printed on my computer skin. Yes, whose full program is the C-Out? It is written inside, inside the Steam app It is written, Using Name Space Standar ki Used, because I have as many classes as I do, C Out and C In With this, study double colon here Using name space stander In the meantime Carli Breakend C Out, Hello World semicolon Jiten Zero What does a compiler do? This program will take all programs together. and converts it into Ubijit code, I mean, all the programs that exist What does he do with it? Lifts it up together and What converts into machine language? Alright So, what does a compiler do? Jago, compiler translate the entire source code I mean this old, ancient source code here Who will convert this into? Converts it into the form of 0.1 What does a compiler do? Compiler things Jet has also written a program I can't even lift a sweatshirt with my jet. Converts it into the Masonic code In executable format It is done by linking on the 1st. He converts it into that format. We don't need to go there, right? So what does this do, and in even more 01 format whatever we have converted It is a program; to run that program Whatever resources you need are fine. All those things are made possible. Lifts it completely from the push. And into what does it convert? In the Masineri language converts it, which is yours, people 01,11,01 Such static positions Converts it for me Okay, in binary language Now the Doga compiler What does a compiler do, and what are its uses? What is done to it, what does the compiler do As I run my program Write this, include iostream Alright, I'm leaving now, you people I want you all to watch the program. I'll erase this. Look, carefully examine this program, what is written here #include using namespace std; Int, Main, Carley Bracket Malo, that our What does a compiler do, compiler syntax It is used to correct errors, correct. What does Syntax Error mean, here is the explanation It will start showing an error if the semicolon is removed. I mean, this syntax It is used to perform error handling. So our method in C++ language It is a compiler-based language. So, meaning that the compiler is for C++ Whatever syntax there is, that synthex Checks it, and sees Whoever is Bhangas, they encourage the entire Poraam. And converts it into machinery code by executing it. It's way too fast. Look, what's written or arranged for the execution I mean, any program that is compiler-based Their executions are very fast. So C++ is also a fast language, right? And what is the disadvantage? that requires an extra step to compile So, as you convert this into machinery code Then it also needs to be converted into an executable file. I mean, an extra step is required, okay? And what is disadvantage? It is difficult to debug and find errors in it. If our program for the goods is 500 lines long We picked him up and executed him. Now we are getting an error There will be many errors. Identify it, then debug the error It will be difficult, okay So these things If an error or something similar occurs, it will take more time. It is correct to find the error and then resolve it. So this is its disadvantage. Now, sorrow becomes one. interpreter What does the interpreter do now? What does the compiler do now? Picks up the entire source code entirely What does he do with it? Converts into machine language Should I tell you, then? That picks up things line by line Converts it into machinery code I mean the machinery code. converts it into object code So what should I do? Whatever statements there are Whatever we have written in the line set of instructions takes up that one statement Will convert it into machinery code it does not produce a I mean, this isn't much of an extra step. does not produce As our compiler was producing that extra step This task does not work with interpreter. It is a thorn. And here too, it says the same thing. The interpreter executes the code line by line. Executes it with him. So, you all read these things. What is written here? Whatever our source code is He will take his code line by line. Then it will give output from it output means in machine code will convert line by line One minute source code to the interpreter first Converts into machine language and then processes Whatever output is generated also displays the output itself But what are the things to understand, look, and read What will the source code do? I will take one line of source code What will you do with him? Will convert into machine language What will you do then? It will take the second line of the source code I mean that What does an interpreter do? Will pick up the code line by line Converts into machine language Now interpreter and But it gives to Prabhaad, logical order, think Or else gives a conditional order. You're writing code There is some error in the code logic. Then he'll give the logical answer, okay? As we know that we are any Then we will start the IDER. While you Gampailar Base Program is on If you divide the number by zero there No one gives any ID card. That's right, that's the difference. Gampailar Base Program Who are the participants in the Inter Base Program now? Python is your Java Script And Ruby is, how is this language This is an interlanguage. Hey, I hope you all are doing well. Explain it, and our advantage with regard to this Thike, and Dogo, the last one left Our assembler, assembler A mid-level language is a type of programming language. You will read when You will go to Class 12 in 8085 Thike, so there it is You will read assembly language Time, this compiler What does it do, as it happens? What does assembly language do? Converts into the budget code, okay, so Here it will be written: VIA, Assembler is a computer Program Date Translate assembly language code into machine code This is a two-line assembly language for you all. Move 5 into AX In this kind of format, whatever language is written They speak assembly language with him. And this language Who performs the task of converting into machine code? assembles So I hope you will explain it to them What is an assembler? What is an interpreter? And this understanding of syntax, it will help you all Efforts have been made to explain in a better way. I hope you will explain things to you people. Alright What do we do now? Let's talk about something. What I just told you all How does the interpreter throw an error? While ours Compiler-based The program that is What does a compiler do, exactly? It gives a syntax error. Alright Then I'm going to my computer system. And by doing things, you people I'm trying to explain it. Alright Hello, friends Whatever is written angle brackets It's fine inside double quotation marks Those things are printed things for us. I've already told you all. Look here, right here It's showing double colon again Alright What shall I write? Hello World Alright So when I write Hello World So my computer Look here Output where it is written Look, where my mouse is going Look here, here is where you all are located So, enable this type of error I mean compiler Because in C++ I already told you all, didn't I? What kind of language is C++? C++-based language Alright So how do you get the error? They give compilation errors I mean, they give syntax-based errors. Now, as I put a semicolon here Alright I hope you all understand. Alright Look here I'll show it again Look here What am I supposed to do here? I am typing the semicolon again here Semicolon pressed When semicolon was pressed And then I ran So what did I find out Alright This is me writing in Python Alright Tai Hob, I'm talking to you all If you know a little bit of Python You will understand then Even if I don't understand it Don't worry about it. What I want to explain to you all that the interpreter provides logical order You cannot divide any number by zero. That was a logical thinking, wasn't it? So what does this do? This gives the logical ID. Interpreter OK Now you people If I write it in C++ So, look, it won't give you an error Look at the date As we move forward in Lexar You people need to do these things with something It will be fine, okay Just look at what I'm doing And try to understand what I am doing. Look, A equals 10 Syntax here is very important. Look, I didn't specify there what kind of data type A was. An integer number is a whole number. What is the value of Tike? Ten hai teke Then the int What should I write for Int B? Zero Tike Then what should I write for Int C equal to? I am A divided by B Then semicolon The compulsion is to impose, and here it is What do we use to print things? We use C out. What do you use C out for? What do I need to C out? If you want me to write what I've written What do they do for that very print? We put double colons. If I put a double colon, what should I write? I write the answer, I write. You won't understand LIGHT Don't worry about it. In our upcoming lecture, we We will understand this in an even better way. So you all must understand the things. I'm just telling you all What on earth is he going to do now? This will not give any error. Because no matter how many syntaxes you write for it I didn't write anything messy in it. Don't write anything at all. So this won't give any kind of error It will not generate any output at all. floating point exception No error was reported There must be some exception, tell me something. Now, exception handling, such as The concept we will study in our upcoming lecture When we go to class 12, there we will be You people could have done these things in an even better way I'll understand, but both of you something There is no error generated. Whenever Hanga came, no matter how So he used to keep some errands going. What used to come here? Is this an error, We will call using a semicolon You don't see it, do you? So I am very much aware that I'll explain a few things. If you agree, then right now I'm going to give you Whatever else about the compiler and the interpreter, and this The concept is that I'll code it right away and send it to you. I tried to explain something. I hope you understand. You must have understood the things, so thank you until then. In my next lecture, I will have a great lecture for all of you. Thank you, thank you so much
