The Preprocessor processes the source program before it is passed to the compiler. The features that preprocessor offers are known as Prepsocessor Directives.

Preprocessing directives are lines in your program that start with `#'. The `#' is followed by an identifier that is the directive name. For EXAMPLE, `#DEFINE' is the directive that defnes a macro. Whitespace is also ALLOWED before and after the `#'. A preprocessing directive cannot be more than one line in normal CIRCUMSTANCES. Some directive NAMES require arguments.View answers in details
