What is Armstrong number?

An Armstrong number is an n-digit number that is equal to the sum of the nth powers of its digits.

For Example: 407 = 43 + 03 + 73 = 64 + 0 + 343 = 407

#include<stdio.h>
int main()
{
    int num, sum = 0, i, r;

    //Reading a number from user
    printf("Please enter a number: ");
    scanf("%d",&num);

    //Finding armstrong number or not
    for(i = num; i>0; i=i/10)
    {
        r = i%10;
        sum = sum + r * r * r;
    }
     if ( num == sum ){
        printf("%d is an armstrong number.",num);
     }
    else{
        printf("%d is not an armstrong number.",num);
    }

    return 0;
}

Result:

Please enter a number: 407

407 is an armstrong number.
