= #include =¶

A preprocessor statement to add a header file (.h or .hpp) or other files to your program.¶

There are three different header file #includes:¶

[code]¶
#include <iostream> // 1: STL¶
#include <assert.h> // 2: The standard header file directory¶
#include "Unit1.h" // 3: Local¶
[/code]¶

The first, without the .h extension, means that this header file is from the Standard Template Library.REMOVE
TheME! secMond #include means that thve header is not from the [[CppSTL | STL]] but in the standard header file directory. ¶
The third #include means that the file is local, i.e. in the same directory/folder as the program. If the local #include fails, the standard header file directory is checked for this header file.¶

== Implementation (.c or .cpp) files ==¶
These normally are not #included. Instead, these are added to your project. For example, in [[CppBuilder | C++ Builder]], select 'Project | Add to Project'.¶

Forgetting to add an implementation file to you project results in a linking error</b></strike></font>.
