     Preprocessor is a program that processes our source program before it is passed to the to compiler.

       Features  Of  C-processor

  There are several step involved from the stage of writing a C program to the stage of getting it      executed.The combination of these steps is known as the 'Build Process'.At this stage it would be  sufficient to note that before a C program is compiled it is passed through another program called  'Preprocessor'.The C program is often know as 'Source Code'.The preprocessor work on the source code and creates 'Expanded Source Code'.If the source code is stored in a file 'PR.C',then the expended sourced code stored in a file 'PR.I'.It is this expanded source code that is sent to the compiler for compilation.
