Description

A generic Preprocessor is a computer application that processes data before it is passed on to a computer program for further processing. Preprocessors are typically used to convert data from one format to another, or to add features to a program. For example, a preprocessor might be used to combine several source code files into one, to create a list of defined constants, or to generate a header file containing function prototypes. Preprocessors can also be used to perform calculations, or to test for certain conditions before passing data on to the program. Preprocessors are usually part of a larger programming language, and are used to reduce the amount of code that needs to be written and maintained.
