{
    int num;

    /* Input a number from user */
    printf("Enter any number to check even or odd: ");
    scanf("%d", &num);

    /* 
     * If n%2==0 then 
     *     print it is even
     * else
     *     print it is odd
     */
    (num%2 == 0) 
        ? printf("The number is EVEN") 
        : printf("The number is ODD");

    return 0;
}

Another approach of writing the same program as.

 
/**

    printf("Enter any number to check even or odd: ");
    scanf("%d", &num);

    /* Print Even if (num%2==0) */
