As its name suggests,the preprocesser processer is a program which process the source code before the actual compilation of the source code takes place..if there is any macro template in the program,it is replaced by its macro expansion.ex:- #define pi 3.14 so where u use pi in the program ,it will be relaced by its corresponding expansion,i.e its value 3.14(here)here #define is the preprocesser directive,just like other directives #include ,#ifdef etc.
