The header file or include file is a source code file that a compiler, usually a C or C++ compiler, automatically includes when processing another file.

Programmers typically specify header files to process using a directive in the source file. For example, to automatically include the header file "foo.h", one would type this in top of a C file:

#include "foo.h"
