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, last; // Reading number Console.Write("Enter any number: "); num = Convert.ToInt32(Console.ReadLine()); last = num % 10; Console.WriteLine("The last digit of entered number: "+ last); while (num >= 10) { num = num / 10; } Console.WriteLine("The first digit of entered number: "+ num); Console.ReadLine(); } }
