In 54 Minutes, Understand the whole C and C++ compilation process

►Lesson Description: I've seen enough folks struggle with compiling in C and C++ that it is time for a full video to understand the process. As a result of understanding the compilation process, you can understand why a project should be split into smaller components, and how that makes your code faster to compile, easier to debug, and dare I say...more fun to work with!

boy i wish i had seen this video when I was an undergrad

[lucassilveira]

That was the best lecture about compilers on the whole internet. Thanks Mike!

[husenpatel]

Its amazing to figure out how many layers of abstraction we are living upon. not to mention python or javascript like langauges which are much higher level than c++.

[kjollyman]

I still watch these even after graduating 😅 thank you for the hard work!

[min-yenlu]

This is a really great video!!! I hope that I could see it when I started learning programming....
This contains everything you need to learn for compiling process....
It would have spared lots of wasted time.

[saberlite]

Impeccable explanation. I wish my college had professors like you who would explain the nitty gritty details and not just go through presentation slides.

[olegwizex]

Thank you! Great video and explanation.

[oscarmvl]

What a great video! It was great to find such a cohesive video about the compiling process, thank you for creating this!

[zikangxiong]

This video gives quite a practical overview. Tools like ldd and those flags are really most frequently used in any meaningful projects. Only those who really use C/C++ can summarize it in such a concise but practical way!

[hsociety]

Bro this channel is soo damn underrated-- you should have like billion views on this video and billion subscribers

[sabrinagschwendtner]

Thank you for this video! It helped me understand a lot of concepts that I missed or that weren't even included in my lectures in the first place. I have my bachelor's exam in a little over a week, so I am currently trying to fill the gaps in my knowledge and you definitely helped me with that! :D

[jovannyswicktutorials]

This is special and deserves more views and likes. Well explained.

[DocteurZeuhl]

Thank you so much for this video. It really helped me put together every piece of information I have gathered along the way so far, and already gave me ideas on how to solve the (pretty sophisticated) linking issues I am currently facing. Incredible video ❤

[dontbemadsunshine]

This is awesome. Im doing a masters in a.i. next year and we will be having to use a lot of different languages throughout the course, i thought learning c/c++ would be advantageous as my first language. Thanks you very much for this!

[nikolasyo]

Nice Video!!! So many things make sense now. I tried to include SDL in my C++ project on windows some days ago. Sould have watched this video before. would have saved me a lot of trouble.

[tamajitbanerjee]

Thank you, sir !! The content was very good.

[lln]

great explanation! Nice to see a Linux command-line approach, since now I just saw Visual Studio

[willianpessoa]

This video has been incredibly helpful to me. Thank you for sharing.

I've been a subscriber to your channel for some time now. I stumbled upon it while researching Design Patterns (which I'm still trying to master), but this video greatly assisted me in completing a questionnaire for my Computer Science Coursea at UFRJ

I genuinely appreciate your content and aspire to become a professional like you in the future.

[DCKUR]

Very detailed, thanks for creating this video :)

Superb video. Super useful. Many Thanks for sharing your knowledge. Easy sub.
As an old fart hobbyist, currently getting back into C++, I'm amazed how few C++ resources, be they books or online courses, cover this build stuff in any detail. It seems most of them want you installing Visual Studio etc on day one, then there's a bit of magic hand waving, assuring you that the IDE will take care of all these things, and I'm sure it will, but I do like to know what my tools are doing for me. Then I try to install raylib and I become painfully aware that I don't have a clue about building from the command line.
Again, Many Thanks for sharing your knowledge. I really like your teaching style. I noticed you have series on C++ itself, and also SDL2. I have a feeling I may end up using SDL2 instead of raylib. :-)
