What You Should Include in a Header File ?

Question

Dependra Pathak · Answer

A header file should begin and end with #include guards to guarantee that it?s not #included more than once during the same compilation session. A typical #include guard looks as follows:
// from stdlib.h
#ifndef STDLIB_INCLUDED // included for the first time?
#define STDLIB_INCLUDED
