I like the awesome-algorithms link, but some of the code linked is definitely not perfect. A few questionable things from one of the header files [0] in https://github.com/TheAlgorithms/C:

- Defines a macro with no parentheses

- Uses unsigned for length and capacity (should be size_t)

- Uses () instead of (void) for an empty parameter list

- Useless use of "extern" for function declarations

- I think that leading double underscores and structures ending with _t are reserved identifiers, but I don't really have a good source for this
