I was at school when pocket calculators first appeared. Now 65, sitting here on a Saturday morning, learning c++ from a young man who's worked in the games industry. Amazing what is possible on the internet. I remember when the only hope you had of learning this kind of thing was getting hold of a good book (and that was when libraries closed early on Saturday and were closed on Sunday) Many Thanks for sharing your knowledge.
When I was in school smartphones came along, The knowledge of the world in the palm of your hand! I bet when I'm 65 We'll have room temperature quantum computers in our homes
Damn dude, it's insane to see how you've gone from doing some low quality code rambling to neat, organized and well edited professional tutorials, and from a couple hundred to over 50k subscribers! Great job man, you've helped me tons in the past, keep doing what you're doing!

Douchbag alert! James R, take your own advice, you pretentious asshole! The guy was just giving a compliment. The way you tell people what they should have said, you might as well just write everybody’s comments for them so you approve.
I have watched manu C++ tutotials on youtube in my professional career and I have never come across anyone who can do such a great job at breaking down complicated concepts into a very concise and easy to follow short lectures. You helped me to really understand how this stuff works. I wish that my university professors who taught/teach programming had half of teaching talent you have. Thank you!
I found Cherno yesterday and coming in, my thinking was that C++ was super hard core and probably beyond me at this point. I have to say, after watching this video, I understood everything. I'm not saying I'm smart, I am saying this dude is a great teacher. Clarity, repetition, efficiency of explanations. I am almost thinking C++ might be a better first language to learn than Java. I've learned the basics of Java already as part of my bachelors degree. At this point I'm on the fence about which way to go. But if the lessons are like this one, I don't see C++ being that scary hard language to learn that everyone says it is. And that would be a testament to the teacher. Great work.
I learned C++ as my first language and altough it was quite tricky to wrap your head around some of it’s concepts in the beggining, it made it really easy for me to later learn new languages such as Javascript and Python.
yea, late reply here....but Java as a first language has been considered a pretty bad idea for quite some time now. But don't get me wrong, I'm not one of those folks who thinks if you start off in the "wrong" language that you're RUINED FOREVER (!! -- seriously, some ppl think like this). Java is cool. I think the top2 languages for first timers atm would be Python (by a huge margin) or C (for the "bottom-up" approach).
Actually I think Python is best to learn first, which I luckily did. I think C++ ist more important than Java so I am actually planning on learning C++
@@intuit13 started off with C as part of my bachelor's degree. Makes it way easier to grasp C++ in my opinion. Using Python as a starting point works but the way it's written (and in some cases the way it works) is pretty different to C++. I'd recommend it as a starter but not if your final aim is learning C++.
Wow dude... just wow. I was about 12 or 13 when I first heard of C++... I had found out that its used for video games which instantly struck my interest... but it wasnt until I was about 16 or 17 that I started dabbling in it and I thought it was too difficult for me to understand, and I thought you had to be extremely smart.. I am now 19... and have no idea where my life is going, I have always LOVED the idea of writing my own code, because its the closest thing to actual magic.. I’ve recently started trying to understand the concepts of c++ and how it all works.. I have a basic understanding of it all, and I really really wanna learn it. I’m going to go to college to get a BA in computer science. Whether I help make the next AAA title, or the next microsoft... I just want to code.. I’m very entrepreneurial as well so I don’t see myself working for someone This is the first tutorial of yours that I’ve seen, and you made me understand the most basic c++ program even more than before. I’m looking forward to watching the rest of this series and I hope you continue it.

So, I am a working professional. But I had to teach a friend of mine, the basics of C++. For that, I was looking for some easy videos. Man, This guy explains so well. One thing is for sure when I get married and if I have kids and if they choose to become a Software engineer, this guy is the one I am gonna send my kids for tuitions.
Dude this is high quality stuff! I'm studying Computer Games Development at University and have learnt more from your C++ series than I have all year! Really looking forwards to digging into your OpenGL series. Thanks so much for bringing this great content man and please keep it up :D
Just wanted to say thank you. I tried coding when I was a teen but failed and quit (there was no RUclips back then). My son is interested and I thought we could learn together. Your videos are very well explained and I really appreciate the effort that you put into you videos.
After many tries to get into coding, I again started an approach and found your series here. Well done! As you start with the basics, it feels like it gives me the right entry point to finally understand some fundamental layers I didn't have in the past. So my hope now is, to finally get deeper into coding. Good job!
Once you are past tutorial level throw tutorials into trash and start working on your projects tutorials are going to help you with basics but after that you need to start working on your own with help of google maybe but tutorials shouldn't be part of your daily life anymore.
Your videos should have been the first thing that popped up when I searched C++ tutorial. I went through a 100 video course that skimmed over very important concepts I wish I learned sooner. You're doing a great job!

Even though I like to code in C# (as a hobby in my free time, I am not any professional or something), after watching this video you really caught my interest in watching how the whole c++ thingie works and how everything in programming ties together to create an executable file.

@@TeeHeeWinning Funny you should say that, because I was originally learning C++ to make cheats for CS:GO. It didn't work out for me, as understanding the tricky aspects of C++ is hard, especially for a kid tryna make CS:GO cheats. People learn differently though!
I think this is the first time, I hear someone explaining as simple & understandable as possible, how compiling and linking works in cpp! really great videos!
I've watched so many courses on different programming languages, and they're always so boring, they don't engage me and keep my attention, but everyone of your videos have held my attention and I'm so thankful to have you as a resource.
At 17:00 , If you're compiling this code on VS Code Editor, you might get an error saying : error : c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: C:\Users\ASUS\AppData\Local\Temp\ccoFOfoQ.o:main.cpp:(.text+0x16): undefined reference to `log(char const*)' collect2.exe: error: ld returned 1 exit status Reason : We are getting this error because the text editor (like VS Code) sees different files rather than seeing it as one unit (like in Visual Studio IDE) Solution : If you have two files, 1) main.cpp (includes declaration & calling of function which is situated on other file). 2) log.cpp (definition of the function which wil be used in "main.cpp") Now , use just need to add (#include "log.cpp") in the main.cpp file to include all the function defined in log.cpp at the runtime. also, try changing "#include log.cpp" to "#include log.h" (also rename "log.cpp" to "log.h"), So that the compiler wil take it as a header file. code : > main.cpp #include #include "log.cpp" void log(const char* message); int main(){ log("Hello World"); return 0; } ------------------------------------------------------------- log.cpp #include void log(const char* message){ std::cout
Revisiting all these first videos months after starting learning C++ are so important and so much more informative. Now we can add all the pieces together and finally understand something. That's not possible in the beginning.
I love how your videos contain epic background music. It makes your tutorials and explanations significantly more engaging than anything else I have seen on youtube.
Thank you so much for this video series! It is helping me connect so many dots in game and general programming - concepts that I couldn’t quite grasp from others’ explanations - much appreciated!
Have to learn C++ for a class that the teacher does not know how to code in C++. Your videos are the only ones that aren't hours upon hours long. Cheno you are my only hope.
summary: Our code gets translated into a binary, and the binary can be either a library or an executable file. x86 = win32 There are 2 main options that we can choose when building our code in visual studio. One is the platform, and one is the mode of building. Platform refers to the operating system that we are targeting our app for. It can be either android, windows, mac(?) and so on. Mode of building refers to whether we are building the executable file in debug mode or release mode. Building on release mode runs much faster than debug mode, but is less helpful when debugging. For devlopers until the release of the game, they will be using debug mode untill the project is complete. For each building mode, we can see the micro settings when we right click the project and go to settings. We also take a look at the linker settings in the same window. The output window shows all the errors, and we are expected to debug using the information provided there. We do not want to rely on the error list, since they just display what the machine can understand from the output screen, which is too superficial for actual developers. #include is something that is called a pre-processed statement, meaning that it is being compiled before our main body of code. In this case, #include means that copy and paste everything in a file named to this file. //I believe #include command is something similar to the 'import' command that is used in python to call for modules. Cherno explains that #include is copy and pasting the file into the current file, which is exactly how a module is imported in python through *import library* command. Python also runs the whole code that is in the stated library before running our main code, if we import something from a library! In a project, it is very likely that we will have multiple cpp files. Those cpp files will be converted in to an object file. These have their file extensions as obj, and can be found at certain directories. Those obj files can then be stitched together using the linker. Cherno demonstrates how to use this kind of system. He uses the common 'hello world' code. He then chooses to define a function that prints out hello world, instead of using the common cout
This video helps me understand all of the stuff my professors just kinda brushed over in their lectures I love it! This is the first time I've seen this channel, but I am already a loyal subscriber! Please continue to output this quality content!
Your background music is saving my life, thanks for making "easy to swallow" videos for average audience like me 🙏🏻 the music is making me more focused on the content, other channels without music is boring and easy to be distracted
Small caveat, the computer doesn't start running main right away. There is a bunch of code that c++ inserts before the call to main to set some things up and then it calls main. Same thing happens once main terminates. There is some code c++ inserts to restore state and put the return value in a register
Finally, a C++ tutorial I can recommend to my students. Very well done. One minor nit: stop using std::endl. Just use ' '. ' ' does the same thing as std::endl, and doesn't have the side effect of flushing the output buffer. Normally this won't matter, but if you're writing a large file over, say, a very slow VPN, it can take forever. Besides, it's less to type.
This video left me speechless. Very, VERY useful, brief and qualitative. One of rare treasures on RUclips. It's a big luck for us to have such vids, so we can learn complicated stuff in such pleasant way (remember those old youtube screencasts made on mobile camera and that murmuring). Good-looking guy with nice recording stuff and speech together with laconic information mixed with really suitable background music. It seems I have no way not to learn c++ :-)
Hail, Cherno! Woo! I now have VS 2017. I certainly have been enjoying VS 2015. VS 2017 looks way better and is way cooler. I love your video style, the quick short talks with cuts and the music. (5/5)
Really like this new series, I can see all the work you put into it so that it becomes a reference in the future. Good plan imo. Looking forward to learn things though :P
Thank you for this great video! I have a question: instead of a declaration of a function in another file, can you use #include and then the file name? What if you had a file with ten functions, do you need to declare each function, or can you just #include the file containing the ten functions?
I love your teaching style and easy to understand explanations. One suggestion (for me personally) would be to slow down just slightly (rewinding to listen and understand gets annoying after a while) and turn the music down a little (maybe lower 10-20%). Keep up the great work!
It is profound that you include how #includes are preprocessed, pun intended. This becomes very important later in the linking video. Your ability to teach what you understand is very impressive and very helpful to us that are just learning C++. You clearly understand what we need to know. Notice my grey beard; this is not my first C++ rodeo! Thanks.
If you need two different log functions that have the same parameters, you need to either rename the function, or use a namespace (like the std:: thing in front of cout). Another thing that C++ has is function overloading, which enables you to have multiple functions named "Log" as long as they have different parameters to the function. (ie. Log(int i); or Log(char *str);) I'm sure Yan will cover this eventually.
This is so amazing. I wasn't looking to learn about how C++ works right now but this was so engaging and informative. I was hooked the whole time. well done.
i cant implement the solution here once i add the void function and debug .. it throws Compiler Error C2882 .. our code is exactly the same. i am wondering if things have changed since he made the video set?
You are like a fresh breeze. I am a software engineer. I came here through PS5 tech demo and saw you are an X EA developer. Your teaching style is just amazing. Really liked your videos.
You wouldn't do it this way normally. You declare the function in something called a header file, so you still use a declaration but in this case it's usually not called a forward declaration. You would have a file called Log.h and there you would write the declaration, then you would have a file called Log.cpp where you write the actual code of the log function. Then you include Log.h in all the .cpp file that use that function. Actually when you include iostream, you basically include all the declarations of the iostream header file, which is not that different from including header files that you have written yourself.
There are some things that you can not do in Python, like custom memory management. Now you can say that is not really something that the user will be aware of, but then there are also some OS functions and access to hardware, that can not be done directly in Python. You can always write a C library and load it into Python, but that is no longer pure Python.
MsJavaWof, you do not really need to access memory directly, unless you are confident enough you will do a better job than the GC, again trying to make things faster! Also, I am talking about working on a hypothetical problem rather than extending or interfacing with an existing solution... how many Linux kernel driver writers have you actually met in person so far? ;)
Hi, keep up the great work. I have found your videos extremely useful, but I was recently on your game programming series, but I have seen that you haven't finished it. I was wondering if you had any intentions to resume that series because I love how you explain everything in detail in that series. You have gone so far, so don't quit now.
In actually std::cout makes use of something called operator overloading. But in essence, somewhere in the iostream library is a function that does the printing. And so, writing std::cout

@@TeeHeeWinning Funny you should say that, because I was originally learning C++ to make cheats for CS:GO. It didn't work out for me, as understanding the tricky aspects of C++ is hard, especially for a kid tryna make CS:GO cheats. People learn differently though!
I think this is the first time, I hear someone explaining as simple & understandable as possible, how compiling and linking works in cpp! really great videos!
Thanks for your videos; they're very good. Please continue with the C++ series.
Background music and your voice made this explanation truly incredible! Thanks ☺
4:35 I wasn't paying attention and heard "Pedophiles" instead of "header files"
same here.. been spending way too much time on pizzagate and qanon vids
Do pedos keep their CP in a folder named Pedo Files? It's 3AM and this is keeping me up.
Polluted mind test
Ah yes the famous Pedophiles subject of the C++ language, every developers goes through it
will talk about "pedophiles" in more depth. :)
I've watched so many courses on different programming languages, and they're always so boring, they don't engage me and keep my attention, but everyone of your videos have held my attention and I'm so thankful to have you as a resource.
Your tutorials are amazing!!! Thank you so much
I've been coding in C++ for 6 years now and this is the first time I know these information in this video. Thanks cherno
The man said that the compiler will trust us! Classic.
I DONT WANT TO WAIT FOR THE NEXT VIDEO PLEASE.
dayum, you are a life saver! providing such background music was very ingenious touch - puts you in a state of productive trance
At 17:00 , If you're compiling this code on VS Code Editor, you might get an error saying :
error :
c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: C:\Users\ASUS\AppData\Local\Temp\ccoFOfoQ.o:main.cpp:(.text+0x16): undefined reference to `log(char const*)'
collect2.exe: error: ld returned 1 exit status
Reason : We are getting this error because the text editor (like VS Code) sees different files rather than seeing it as one unit (like in Visual Studio IDE)
Solution :
If you have two files, 1) main.cpp (includes declaration & calling of function which is situated on other file).
2) log.cpp (definition of the function which wil be used in "main.cpp")
Now , use just need to add (#include "log.cpp") in the main.cpp file to include all the function defined in log.cpp at the runtime.
also, try changing "#include log.cpp" to "#include log.h" (also rename "log.cpp" to "log.h"), So that the compiler wil take it as a header file.
code :
> main.cpp
#include
#include "log.cpp"
void log(const char* message);
int main(){
log("Hello World");
return 0;
}
-------------------------------------------------------------
log.cpp
#include
void log(const char* message){
std::cout
Revisiting all these first videos months after starting learning C++ are so important and so much more informative. Now we can add all the pieces together and finally understand something. That's not possible in the beginning.
The music here makes me feel like I'm planning to sneak into a top secret military base
I love how your videos contain epic background music. It makes your tutorials and explanations significantly more engaging than anything else I have seen on youtube.
Excellent video ! That was extremely helpful. This basics stuff is so poorly taught in most tutorials.
Thank you so much for this video series! It is helping me connect so many dots in game and general programming - concepts that I couldn’t quite grasp from others’ explanations - much appreciated!
Dude when you type c++ in youtube your channel does not appear any soon, i found you on a twitter mention. Why youtube is doing this to us?
Have to learn C++ for a class that the teacher does not know how to code in C++. Your videos are the only ones that aren't hours upon hours long. Cheno you are my only hope.
summary:
Our code gets translated into a binary, and the binary can be either a library or an executable file.
x86 = win32
There are 2 main options that we can choose when building our code in visual studio. One is the platform, and one is the mode of building.
Platform refers to the operating system that we are targeting our app for. It can be either android, windows, mac(?) and so on.
Mode of building refers to whether we are building the executable file in debug mode or release mode. Building on release mode runs much faster than debug mode, but is less helpful when debugging. For devlopers until the release of the game, they will be using debug mode untill the project is complete.
For each building mode, we can see the micro settings when we right click the project and go to settings. We also take a look at the linker settings in the same window.
The output window shows all the errors, and we are expected to debug using the information provided there. We do not want to rely on the error list, since they just display what the machine can understand from the output screen, which is too superficial for actual developers.
#include is something that is called a pre-processed statement, meaning that it is being compiled before our main body of code. In this case, #include means that copy and paste everything in a file named to this file.
//I believe #include command is something similar to the 'import' command that is used in python to call for modules. Cherno explains that #include is copy and pasting the file into the current file, which is exactly how a module is imported in python through *import library* command. Python also runs the whole code that is in the stated library before running our main code, if we import something from a library!
In a project, it is very likely that we will have multiple cpp files. Those cpp files will be converted in to an object file. These have their file extensions as obj, and can be found at certain directories. Those obj files can then be stitched together using the linker.
Cherno demonstrates how to use this kind of system. He uses the common 'hello world' code. He then chooses to define a function that prints out hello world, instead of using the common cout
thank you
why couldn't they have combined the simplicity of python with the power of c++
Salute!
Thank you very much! This was very useful.
This video helps me understand all of the stuff my professors just kinda brushed over in their lectures I love it! This is the first time I've seen this channel, but I am already a loyal subscriber! Please continue to output this quality content!
Your background music is saving my life, thanks for making "easy to swallow" videos for average audience like me 🙏🏻 the music is making me more focused on the content, other channels without music is boring and easy to be distracted
omg exactly, the music blends in with the tension of the explanation sooo well
Small caveat, the computer doesn't start running main right away. There is a bunch of code that c++ inserts before the call to main to set some things up and then it calls main. Same thing happens once main terminates. There is some code c++ inserts to restore state and put the return value in a register
Finally, a C++ tutorial I can recommend to my students. Very well done.
One minor nit: stop using std::endl. Just use '
'. '
' does the same thing as std::endl, and doesn't have the side effect of flushing the output buffer. Normally this won't matter, but if you're writing a large file over, say, a very slow VPN, it can take forever. Besides, it's less to type.
This video left me speechless. Very, VERY useful, brief and qualitative. One of rare treasures on RUclips. It's a big luck for us to have such vids, so we can learn complicated stuff in such pleasant way (remember those old youtube screencasts made on mobile camera and that murmuring). Good-looking guy with nice recording stuff and speech together with laconic information mixed with really suitable background music. It seems I have no way not to learn c++ :-)
Hail, Cherno!
Woo! I now have VS 2017. I certainly have been enjoying VS 2015.
VS 2017 looks way better and is way cooler.
I love your video style, the quick short talks with cuts and the music.
(5/5)
Really like this new series, I can see all the work you put into it so that it becomes a reference in the future. Good plan imo. Looking forward to learn things though :P
Love the background music - is this a playlist you have. could you drop artist in here?
The next two videos are sooo important. They will give you hip boots to wade around in the error swamps that you will cause in the future.
*cin.get()*
For entering any character not only enter button.
Thank you, was wondering how the enter button was specified.
Cool channel C 4 Code I subed
I appreciate your videos, very thorough, concise and organized! ive been learning alot about c++ because of you and these videos
Thank you for this great video! I have a question: instead of a declaration of a function in another file, can you use #include and then the file name? What if you had a file with ten functions, do you need to declare each function, or can you just #include the file containing the ten functions?
I love your teaching style and easy to understand explanations. One suggestion (for me personally) would be to slow down just slightly (rewinding to listen and understand gets annoying after a while) and turn the music down a little (maybe lower 10-20%). Keep up the great work!
MORE MORE MORE!
It is profound that you include how #includes are preprocessed, pun intended. This becomes very important later in the linking video. Your ability to teach what you understand is very impressive and very helpful to us that are just learning C++. You clearly understand what we need to know. Notice my grey beard; this is not my first C++ rodeo! Thanks.
that was nice. just like always.
Just amazingly well explained! The lowkey background music is so relaxing, thus enabling better earning.
Small correction: 1:33 cout is an object, not a function
3 years later and this still being the best C++ course! Thanks you!
Great explanation. Thank you.
What is the name of music in background?
I have started with your training. I have experience in C# and I want to jump to C++. You explain everything very good. Thank you.
What happens if you have another cpp file with another "Log" function that has a different body? Which function will be executed?
hululu36 it will throw an error about redeclaration of a function.
If you need two different log functions that have the same parameters, you need to either rename the function, or use a namespace (like the std:: thing in front of cout).
Another thing that C++ has is function overloading, which enables you to have multiple functions named "Log" as long as they have different parameters to the function. (ie. Log(int i); or Log(char *str);)
I'm sure Yan will cover this eventually.
^ ^ ^ CLIFFHANGER COMMENT ^ ^ ^
there are ways to make that work, but I don't think it's important just yet.
Maybe the linker complains about an ambiguous reference? sry, idk.
This is so amazing. I wasn't looking to learn about how C++ works right now but this was so engaging and informative. I was hooked the whole time. well done.
where did you learn all of this?
@math im curious too
Ther Cherno is the only RUclipsr where you have to slow down his videos because he gets straight to the point so fast xD
I feel like with a big c++ project you should just put "using namespace std;" line in the top of your code.
He made a video explaining why it might actually be _worse_ to use "using namespace std;".
i cant implement the solution here once i add the void function and debug .. it throws Compiler Error C2882 .. our code is exactly the same. i am wondering if things have changed since he made the video set?
@@reiter2148 link?
You are like a fresh breeze. I am a software engineer. I came here through PS5 tech demo and saw you are an X EA developer. Your teaching style is just amazing. Really liked your videos.
music is kinda distracting.. I feel like I'm in a mission impossible movie bahaha
I'm taking an online intro to programming class, and you are so much more helpful than my professor! Thanks for your uploads!
Feels complicated as a beginner
That’s because it is complicated
You have no idea how much this helps people man. Thank you so much. I'll hope my determination won't die in few weeks later on.
For larger projects, do you still use forward declaration?
You wouldn't do it this way normally. You declare the function in something called a header file, so you still use a declaration but in this case it's usually not called a forward declaration.
You would have a file called Log.h and there you would write the declaration, then you would have a file called Log.cpp where you write the actual code of the log function. Then you include Log.h in all the .cpp file that use that function.
Actually when you include iostream, you basically include all the declarations of the iostream header file, which is not that different from including header files that you have written yourself.
wow, this is very well explained. Music in the background is also to the point. Hats down. Thanks
c++ is the hardest language when you do it youll find c# java easier atleast i did
Pulsxr, not really. You can do faster with C++, but you can do just as much in Python, Haskell or Lisp
There are some things that you can not do in Python, like custom memory management. Now you can say that is not really something that the user will be aware of, but then there are also some OS functions and access to hardware, that can not be done directly in Python.
You can always write a C library and load it into Python, but that is no longer pure Python.
MsJavaWof, you do not really need to access memory directly, unless you are confident enough you will do a better job than the GC, again trying to make things faster! Also, I am talking about working on a hypothetical problem rather than extending or interfacing with an existing solution... how many Linux kernel driver writers have you actually met in person so far? ;)
Just started this series and loving it. You explain things so well, it makes it so much easier to grasp and learn. thank you so much.
int main(){
court
}
is it true or false
Hi, keep up the great work. I have found your videos extremely useful, but I was recently on your game programming series, but I have seen that you haven't finished it. I was wondering if you had any intentions to resume that series because I love how you explain everything in detail in that series. You have gone so far, so don't quit now.
I had no idea you could do cout.print(). Makes sense but woah.
LOL
In actually std::cout makes use of something called operator overloading. But in essence, somewhere in the iostream library is a function that does the printing. And so, writing std::cout
Me too LOL .i was shocked ,i always hated these two arrows
But we can't use print instead :(
It's not code that will actually work, it's more like a mental model that can help with understanding it.
Great background music choice.
Cherno you deserve more subscribers, this stuff is crazy good. The style is actually pretty cool too.
Terrific tutorials, except for the distracting background music...
Cherno, I haven't seen so far such a great explanation of how C++ works! Thanks for the video. Watching and liking your videos from now on.
Please come into frame differently every time. Please. For me.
why dont you blink
