        num = Convert.ToInt32(Console.ReadLine());
        fact = 1;
        i = 1;
 
        //Run loop from 1 to number entered by user
        while(i <= num)
        {
            fact = fact * i;
            i++;
        }            
 
        Console.Write("Factorial of : "+ num +" is " + fact);
