Guys he obviously doesn't need to know how the compiler works while writting code at his job, yeah it's nice an interesting to know, he pointed that out. Shaming him is nonsense.

summary: Compilation is the process where we convert our plain text of the cpp files into a machine code that is readable by the CPU. It occurs in several steps. The first step is 'preprocessing', which evaluates the proprocess statements. This is followed up py tokenizing, parsing and so on, which will create an abstract data tree(?). In cpp, files have no meaning, and this is to be compared with Javascript. The cpp compiler by default treats .h, .cpp files as the way they are, but we can specifically direct the compiler to treat any random file like any other random file. Therefore, we can just make a .cherno file, and make the compiler treat it like a cpp file. //To be honest, I didn't really get what he meant here. Going over the preprocessing statements, the most common statements are #include, #define, #prgma(?) and so on. #include basically results in the computer to find the file with that name and copy and paste its content into the current file. #define is followed by 2 arguments, and will replace all of the first argument found in the text into the second argument. To see what is going on during the preprocessing stage, we can change the property of our exe file so that it preprocesses to a file, and open the .i file with an text editor. After the preprocessing stage and a series of subsequent stages(cherno didn't cover obout these stages in these video), the compiler results in an obj file. Opening this in an text editor will show hexadecimal looking numbers, which we cannot understand. So we can manipulate the property of the project, click c/c++ --> output files --> assembly output, and change the option from no listing to assembly only listing. Compiling the file after this settings will result in a .asm file being created ind the debug folder, together with the other obj files. This is the readable format of the machine code, and Cherno uses this file to demonstrate how optimization option runs our code faster by reducing redundancy. So in our properties, we can enable optimation, which also requires to change the code generation-> basic runtime check should also be set to default. Cherno makes a 'log' function that returns the message that it receives, and *for no reason*, puts it in the middle of the 'multiply' function he created. Without the optimization, we can see in the .asm file that the compiler calls for the 'log'function for no reason, which slows down the computer by adding additional line to the code. With the optimization turned on and compiling the file again, the whole line that calls for the redundant 'log' line is just gone, because the compiler decides to delete the whole section since it understands that it is unnecessary.

Cherno is very good, but I have also found a few others that you can check out... You can look at Jason Turner's, Javidx9's {OneLoneCoder}, and Bisqwit's channels. A little bit different but Ben Eater explains Computer Science and Computer Engineering very well too, and for any advanced math topics, 3Blue1Brown. I have found these to be some of my favorite channels. Also for C++ if you want an in-depth explanation of the most commonly used std library classes, containers and algorithms check out Bo Qian. For course study, Standford and MIT have great online videos of their courses... There are a few others that I like but they are specialized as they work with APIs such as Direct X, OpenGL, and Vulkan... Other channels pertain to hardware design directly and the process of designing an Instruction Set, Assembler and Assembly language for a custom CPU and its ISA (Instructure Set Architecture). Such as Bilkent Online Courses for their CS-224 course.

CS is more about higher level concepts and pure software design including web development, machine learning/AI, and data science.

So if really depends on what you might want to do with your career. Bare in mind of course that's based on my experience, you should always look at what the programs at your school looks like.

Okay man seriously your C++ tutorials are the best programming tutorials in any language I've ever coded in. It feels so good, even if it's only scratching the surface, getting a good understanding of the underlying nuts and bolts of every line of code. Thank you very much!

I'm on my 3rd year of a computer science degree and I feel like I learned more from your videos than I did in my first 2 years. Absolutely brilliant content, pacing and delivery. I started with Java and touched on other high level languages like C#. I was really weary about moving to C++ as most videos go from the absolute basics of coding so it's difficult to find what you need. This series on the other hand delivered EXACTLY what I was after. So glad I found you. Thank you!

Been programming c++ for just under a year now, consistently. It's amazing how I still learn new things everyday, especially from you. Thanks so much, man. I appreciate it so much.

I just started watching your series. I just want to say that I LOVE how you go into details about everything without making it boring.

I've just started with operating system development at my university (TU Dortmund - Germany) and missed out this whole compilation part (preprocessing, compilation, assembling, linking). This video helped me out a lot. Thanks for that - you've earned yourself a new subscriber! Edit: The quality of your education video is also top notch! Simple, in depth, no annoying background music, good examples. Keep it up!

Super cool to see how the C++ code gets turned into Assembly and Machine Code, and also really helpful to have a better understanding of what the compiler is actually doing!

This is a very well done explication of the c++ compiler.

Quite simply the best learning resource I’ve found online for any topic. Thank you keep up the good work

I'm only a few videos in and it's such a breath of fresh air to find someone who knows their topic well enough to explain it in such easy terms. Preprocessing itself has been so badly explained to me by teachers at all levels and udemy 'instructors' and then here you go and show me that it's perhaps one of the simplest things you can imagine. Thank you. Thank you for the effort you've made in creating this.

I didn't find any person like you to explain in the simplest possible way. I saw an everyday video about programming for 10 years but I never find a person to explain this detail. It's absolutely easy for me because I had experience in programming but if someone new to programming with your video learns readily.

Fast and with some background music, I think it's perfect to hold one's attention. I will recommend this series!

Wow, this series is fantastic. I'm making my way to patreon right now, because I don't want to this to stop.

Your understanding of c++ is very clean, and it has motivated me to watch more videos and continue where I left off trying to understand c++

By far the best video I have ever seen on this topic. Clear, concise, on-topic, with a lot of enlightening examples and with some very interesting background information. Congratulation!

Usually when I work through video courses, I'll watch them at 1.5-2 x speed. When I see the total number of hours, I also factor the speed shift in and determine how much value a course has. Anywayz...none of that applies here :D I've worked through a number of C++ courses, but I can't resist starting from scratch with this series as I've already come across more than I had previously known. While most kids got a teddy-bear as their first gift, I'm sure you were given a laptop and a copy of Programming Principles and Practice Using C++ by Bjarne Stroustrup. No wonder EA are cranking out some amazing titles. I'm sure I'm not alone in saying that I really appreciate your effort and I'll be sure to contribute when I can. Cheers!

Slight constructive feedback. Blink more. You seem to have done jump cuts to make it flow better (which is great) but you also appear to not blink at all during the intro thanks to it. It's noticeable which makes it distracting (and sorta creepy). So yeah, just try to blink normally even though its weird with lights/camera and stuff.

@Sylfa

Yeah, people tend to notice if someone talking to them is blinking too often or not often enough. Since you have bright lights in your eyes in a situation like this you tend to blink too often so you have to consciously avoid doing that, aaaand then you might go the opposite direction. It's not a big deal, but worth thinking of when recording videos.
