    What Are Preprocessor Directives In C?

  • #52902

    C Preprocessor directives:

    Before a C program is compiled in a compiler, the source code is prepared by a program called preprocessor. This procedure is called preprocessing.

    Commands utilized in preprocessor are called preprocessor directives and they start with “#” symbol

    Preprocessing directives are lines in your program that begin with ‘#’. The ‘#’ is trailed by an identifier that is the directive name. For instance, ‘#define’ is the directive that defines a macro. Whitespace is likewise permitted when the ‘#’. A preprocessing directive can’t be more than one line in typical conditions. Some directive names require arguments.
