The C preprocessor or cpp is the macro preprocessor for the C and C++ computer programming languages. The preprocessor provides the ability for the inclusion of header files, macro expansions, conditional compilation, and line control. In many C implementations, it is a separate program invoked by the compiler as the first part of translation. The language of preprocessor directives is only weakly related to the grammar of C, and so is sometimes used to process other kinds of text files.
The #undef directive causes an identifier's preprocessor definition to be forgotten. See The #undef Directive for more information. If the name of the macro being defined occurs in token-string (even as a result of another macro expansion), it is not expanded.A second #define for a macro with the same name generates a warning unless the second token sequence is identical to the first.f the name of the macro being defined occurs in token-string (even as a result of another macro expansion), it is not expanded.
