Introduction
I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability..
using System; using System.Collections.Generic; using System.Linq; using System.Text; public class csharpExercise { static void Main(string[] args) { int num, product = 1; // Reading number Console.Write("Enter any number: "); num = Convert.ToInt32(Console.ReadLine()); // Repeat the steps till n becomes 0 while (num != 0) { product = product * (num % 10); // Remove the last digit from n num = num / 10; } Console.WriteLine("Product of digits = "+ product); Console.ReadLine(); } }
