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
The 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.
Yeah 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.
