C Program to check whether a number is even or odd

 

In this program we make use of the logic that an even number is always divisible by 2.Which means on diving a number by 2 the remainder must be zero.

#include<stdio.h>

#include<conio.h>

void  main()

{

int a;

clrscr();

printf("Enter a number");

scanf("%d",&a);

if(a%2==0)  // comparing the remainder with 0

   printf("EVEN NUMBER");

else 

   printf("ODD NUMBER");

getch();

}


Output:
