Program to Find Whether Given No. is Armstrong or Not


Code:
/*Write a program to find whether given no. is Armstrong or not.
  Example :
           Input - 153
           Output - 1^3 + 5^3 + 3^3 = 153, so it is Armstrong no. */
class Armstrong{
      public static void main(String args[]){
      int num = Integer.parseInt(args[0]);
      int n = num; //use to check at last time
      int check=0,remainder;
      while(num > 0){
           remainder = num % 10;
           check = check + (int)Math.pow(remainder,3);
           num = num / 10;
      }
      if(check == n)
            System.out.println(n+" is an Armstrong Number");
      else
            System.out.println(n+" is not a Armstrong Number");
   }
}

  1. Armstrong Program in C++

    Armstrong number is a number that is the sum of its own digits each raised to the power of the number of digits is equal to the number itself.
    For example 153 is armstrong number, 132 is not prime number. Armstrong program in c++ is very simple and easy to write.
