Why does your header file contain code?
69It's not the case with this meme, but in C++ template definitions have to be defined in the headers if they're not full template specializations
33Oh for fuck sake. I thought the full on retardation hadn't spread to c.

The stone-age called, they want their languages that need header files back!
(I use Rust btw.)
42I know that header files have some pretty horrible issues with templates and cyclic dependencies and so on, but from an organisational perspective I really like them. If I have to implement some complicated algorithm I could easily have a thousand likes + of Code, but the header still quite nicely shows the general structure in one or two screens. Whenever I do classes in python I start wishing for headers at like 300 lines, simply because I loose track of all the functions I already made.
Maybe I'm just not a good python programmer tho.
2I'd say at 1000 lines it usually makes sense to extract some parts into other files. But sure, I guess most obscurities have positive aspects. On the other hand, nothing is stopping you from writing a separate file with only function signatures next to your python scripts. It's just not required, because why would it ;)

Why are you putting the implementation in the .h file? You're supposed to declare in the header and implement in the .cpp files. The meme is reversed
41If C++/C were real languages for real programming they'd enforce this in the compiler.
No sane language designer would say "it is imperative that you do not implement your class in its header file" then write a compiler designer to say "oh you implemented your code in the header file? lol lmao that rocks"
They have played you all for fools.
44not saying it's good design, I ditched C++ long ago. at least the C++20 modules API is gonna fix this, right guys?
6Header files aren't part of the C++ language at all.
Also mandatory "C++/C is not a language"

1If C++/C were real languages for real programming they'd enforce unreadability in the compiler.
No sane language designer would say "It is imperative that you write the most unreadable code possible" then write a compiler that says "oh your code doesn't triple dereference pointers? lol lmao that rocks"
They have played you all for fools.

There is an issue with templated code where the implementation does have to be in the header as well, though that is not the case here. C++20 introduced modules which I guess were meant to sort out this mess, but it has been a rocky road getting them to be supported by compilers.
12The reason is that header files are pretty much copy/pasted into your c files when you include them. so the code in them keeps getting recompiled for every c file, which drastically increases overall build times. If you only declare in the header and have one c file implementing the functions you compile them only once.
-3Yeah that's why you're supposed to use header guards... If you don't and include your header in multiple places your program straight up won't compile.

I haven't codes anything in C++ for such a long time, I completely forgot how to.
4It's horrible, I did pure C for years but now I have to code in C++11 or worst like C++17
