Program to find Armstrong number

 What is Armstrong number

 If sum of cube of each digit in number is equal to that number then its called as armstrong number

 Ex.1

 Conceder number 153

 Calculate sum of cube of 1,5 and 3

   1^3+5^3+3^3=153

 Hence 153=153

 Then 153 is Armstrong number

 Ex.2

 Conceder number 122

   1^3+2^3+2^3=17

 Then 122 is not Armstrong number

class armstrong

{

public static void

main(String args[])

{

  int i,p,rem,sum,n=999;

 

 

   for(i=0;i<n;i++)

   {

    p=i;

    sum=0;

    while(p!=0)

     {

      rem=p%10;

      p=p/10;

      sum=sum+(rem*rem*rem);

     }

      if(sum==i)

      System.out.println(

"amstrong="+i);

   }

}
