This is a simple C programs which checks if a given number is even or odd. An even number is one that is completely divisible by 2 and an odd number is one which is not.
C Program: Check if given number is Even or Odd
#include <stdio.h>
int main()
{
int number;/*Variable Declaration*/
printf ("Enter any number: ");
scanf ("%d", &number);/*Number input by the user*/
if (number % 2 == 0)/*Checks if number is divisible by 2*/
printf ("Number is Even");
else
printf ("Number is Odd");
return 0;
}
Output
This program uses a single variable 'number' which stores the integer that is input by the user. The main task is done by the if statement:
if (number % 2 == 0)/*Checks if number is divisible by 2*/
printf ("Number is Even");
else
printf ("Number is Odd");
The if statement uses modular division. The modular division works slight differently than ordinary division in this way that it gives the remainder. So:
16 % 3 = 1
Therefore, if a number is completely divisible by any number then modular division will give 0.
