     for(i=1; i<=500; i++)

     {

          neen = i;

          num=i;

          sum=0;

          while(num!=0)

          {

              cube=0;

              a=num%10;

              num=num/10;

              cube=a*a*a;

             

              sum=sum+cube;

          }

          if(neen == sum)

          printf("\n %d is Armstrong Number",neen);
