[shivpujankumarprajapati]

Hi,
Q number 19, whatever you shown that is function definition.
Let me explain
Function declaration:
Int function_name(int);
Function definition:
Int function_name(int a)
{
//Function body
return
/* return 1 Integer value because function is return type of Integer. */
}

Function call in main function:
void main ()
{
function_name(2);
/* In function parameter we need to pass 1 integer value. */
}
