The GNU C Preprocessor

This part of the documentation is a modified version of the GNU CPP Manual. Therefore it is licensed under the GNU Free Documentation License.

The C preprocessor is a macro processor that is used automatically by the C compiler to transform your program before actual compilation. It is called a macro processor because it allows you to define macros, which are brief abbreviations for longer constructs.
