C++
Include Files
A programmer can include multiple additional files in a C++ program. These files, called include files, are used to access libraries or to break a program into multiple parts. For defined files of the C++ standard library, such files are included using the #include statement and the name of the file excluding the -h part of the file name.
iostream include statement example:
#include <iostream>
It is also possible to include other files that are not part of the standard libraries. These are included using the following style of statement:
Non-standard library include statement:
#include "include file.type"
Note that recursive inclusions will cause problems and should be avoided.
