    while(an>0){

  2. //using C#
    int num, sum = 0;
    num = Convert.ToInt32(Console.ReadLine());
    for (int i = num; i > 0;)
    {
    sum += (i % 10) * (i % 10) * (i % 10);
    i = i / 10;

    }
    if(sum==num)
    {
    Console.WriteLine("No is armstrong");
    }
    else
    {
    Console.WriteLine("No is not armstrong ");
    }
    Console.ReadLine();
    }
