Answer 2

Functions calling with example:

• When a specific task is performed by a group of statements in a program it refers to a function.
• There will be at least one function in a program for performing the desired task.
• Each function will be assigned with a certain task and it will be performed when it is called in the main function.
• The syntax for defining a function is as follows:

return_type function_name(list of parameter) {

  the function body

}

• The function should be called for using it.
• When a function is called in a program, the control will be passed to the function.
• The function that is called will then be executed and the control will be again transferred to the program.

For example:

int main () {

  int x = 10;

  int y = 20;

  int ret;

   int Z = add(x, y); /*calls the function add(x,y)*/

 printf( "Added value is : %d\n", Z );

return 0;

}
