In [[C (programming language)|C]] and [[C++]], the language supports a simple [[Macro (computer science)|macro]] [[preprocessor]]. Source lines that should be handled by the preprocessor, such as <code>#define</code> and <code>#include</code> are referred to as ''preprocessor directives''.

Importance: '''[https://seanomos.com/knowledge/c-language-programming-important-books.html Preprocessor directives]''' provide a way to include files, define macros, and conditionally compile code, which can make programs more modular and manageable.

Syntactic constructs similar to C's preprocessor directives, such as [[C Sharp (programming language)|C#]]'s <code>#if</code>, are also typically called "directives", although in these cases there may not be any real preprocessing phase involved.
