C preprocessor?
Article Introduction:C programming language supports preprocessors for efficient working of programs. The C preprocessor is a macro preprocessor for C-based programming languages. The preprocessor provides the compiler with the ability to include header files, macro expansion, conditional compilation, and line control in an explicit manner. The #hash tag is used to define preprocessors, i.e. all preprocessors start with #. This is followed by the name of the preprocessor without any spaces. Here is a list of C preprocessors. S.No. Preprocessor Description 1. #include includes specific header files from files. 2. #define defines preprocessor macros. 3. #undef Undefines the preprocessor macro 4. #if checks the compile-time condition and evaluates to a True value. 5. #else as a replacement for if preprocessor
