Check Armstrong Number

Q. 98. Program to accept a number and check if its an Armstrong number (sum of cubes of each digit = that number. Eg: 153, 371, 407).

Copy Code: 

#include <iostream>

using namespace std;

int main()

{

  int i, n, s=0, p, a[ 10 ];

  cout << " Enter a possible Armstrong Number ";  cin >> n;  p = n;

  for ( i=0 ; n>0 ; ++i )

   {

     a[ i ] = n % 10;

     n = n/10;

     s = s + a[ i ] * a[ i ] * a[ i ] ;

   }

  if (s==p)

     cout << p << " is ARMSTRONG ";

  else 

     cout << p << " is NOT ARMSTRONG";

  return 0;

}
