static function (process-oriented static keyword)

The function is defined as a static function by adding the static keyword before the return type of the function. A static function differs from a normal function in that it can only be seen in the file that declares it and cannot be used by other files.

Examples of static functions:

1#include <iostream>2 using namespacestd;3 4 Static voidFN ();//declaring static functions5 6 intMain ()7 {8 fn ();9       return 0; Ten } One  A voidFN ()//Defining static Functions - { -      intn = -; thecout <<n<<Endl;  -}

Benefits of defining static functions:

Static functions cannot be used by other files;

Functions with the same name can be defined in other files, and no conflicts occur.
