Write a program  in c++ to input a number and check if it is  armstrong or not

Armstrong Number : Armstrong number is a number that is equal to the sum of cubes of its digits. For example 0, 1, 153, 370, 371 and 407 are the Armstrong numbers

#include <iostream>

using namespace std;

int main()

{

    int num, a, ldigit, cube = 0;

    cout << "Enter A Number : ";

    cin >> num;

    a = num;

    while (a != 0)

    {

        ldigit = a % 10;

        cube += ldigit * ldigit * ldigit;

        a /= 10;

    }

    if (cube == num)

        cout << num << " is armstrong number ";

    else

        cout << num << " is not a armstrong number";

    return 0;

}

OUTPUT

1. 

     Enter A Number : 371

     371 is armstrong number 

2. 

     Enter A Number : 476

     476 is not a armstrong number
