Stdio.h

[wilbersmith]

kindly help me understand how <stdio.h> works.

[Moschops]

It's a C header file. You write

#include <stdio.h>

and then the preprocessor finds the file named stdio.h and copies the whole thing exactly into your code where you wrote #include <stdio.h>

You then are able to call the functions listed here:

Do not use #include <stdio.h>

Do use #include <cstdio>
