Including Header Files in C++

A C++ program can include header files. They are used to provide either an interface, which gives function prototypes for definition, or to provide pre-defined definitions.

//for standard system header files, like stdio.h. Will search standard system directories
#include <file> 
//for header files built by the user, within the source code's directory
#include "file"


These header files are included and compiled by the preprocessor.

#include <stdio.h>
#include "myHeader.h"
