Write a C# Sharp program to find the Armstrong number for a given range of number

/*When the sum of the cube of the individual digits of a number*/  
/*is equal to that number, the number is called Armstrong number. For example 153.*/  
/*Sum of its divisor is 13 + 53;+ 33; = 1+125+27 = 153*/
using System;

{
    int num,r,sum,temp;
    int stno,enno;
	
	Console.Write("\n\n");
    Console.Write("Find the Armstrong number for a given range of number:\n");
    Console.Write("--------------------------------------------------------");
    Console.Write("\n\n");
