Types of Function

A function is a process or task that does some operation in the program. Some programming languages may contain built-in functions for certain commonly used tasks. Most programming languages also support user-defined functions, which means a user can write their own function to perform some operation. There are some libraries or header files that contain built-in functions for performing certain tasks.
