Functions:

  Functions are one of the fundamental building blocks of C++. The every program must consists single function called main().

  Syntax of user defines function is as below:

1.    return_data_type function_name(argument list)

2.    {

3.         // Body part of user define function

4.    }

          Line number 1 indicates the function header.

        Line number 2 and 4 indicates the begin and end using ‘{‘ and ‘}’ respectively. More than one statement is called as Block of statements which must be enclosed in the begin and end.

      The body of a user-defined function can contain any number of statements, at least one statement. That must be enclosed in the begin and end.
