Program to Check Whether a Number is Even or Odd in C

Numbers perfectly divisible by 2 are known even numbers and numbers which are not divisible by 2 are called odd numbers. This program takes an integer from user and checks whether that number is even or odd and displays the result.
#include <stdio.h>
#include <conio.h>
main(){
      int n;
      printf("Enter an integer you want to check: ");
      scanf("%d",&n);
      if((n%2)==0)      /* Checking whether remainder is 0 or not. */
           printf("%d is even.",n);
      else
           printf("%d is odd.",n);
     getch();
}
Result
Enter an integer you want to check: 5
5 is odd.

Enter an integer you want to check: 10
10 is even.
In this program, user is asked to enter an integer which is stored in variable n. Then, the remainder is found when that number is divided by 2 and checked whether remainder is 0 or not. If remainder is 0 then, that number is even otherwise that number is odd. This task is performed using if...else statement in C programming and the result is displayed.
