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; public class csharpExercise { static void Main(string[] args) { int weeknumber; //Reading week no from user Console.WriteLine("Enter week number(1-7): "); weeknumber = Convert.ToInt32(Console.ReadLine()); switch (weeknumber) { case 1: Console.WriteLine("Monday"); break; case 2: Console.WriteLine("Tuesday"); break; case 3: Console.WriteLine("Wednesday"); break; case 4: Console.WriteLine("Thursday"); break; case 5: Console.WriteLine("Friday"); break; case 6: Console.WriteLine("Saturday"); break; case 7: Console.WriteLine("Sunday"); break; default: Console.WriteLine("Invalid input! Please enter week no. between 1-7."); break; } Console.ReadLine(); } }
