Built In Functions

In these Functions rather than specifying the value inside a return

statement, we can specify a condition in the return statement.

If the given condition is TRUE 1 is returned. If FALSE then 0 is returned by

the Function.

Since 0 and 1 are INTEGERS, BUILT IN FUNCTIONS always return INTEGER

TYPE values.

All controls STRUCTURES can be Designed as Built in FUNCTIONS, because

when the parameter is ZERO, then the value returned is FALSE else the

returned Value is TRUE.

Program

#include<stdio.h>

void main()

{

int Even(int);

int a;

printf("\nEnter a Numeric Value : ");

scanf("%d", &a);

if(Even(a))

printf("\nThe Given Number %d is an Even Number.", a);

else

printf("\nThe Given Number %d is an Odd Number.", a);

}

int Even(int n)

{

return(n % 2 == 0);

}
