    printf("enter a number\n");

    scanf("%d",&num);

    real_num=num;

    while(real_num!=0){

    rem=real_num%10;

    res+=rem*rem*rem;

    real_num/=10;

    }

     if(num==res)

     { printf("%d is an armstrong number",num); }

     else

     printf("%d is not an armstrong number",num);
