C# - Read Number and Check ODD or EVEN

---

I have given here a C# program to read number and check ODD or EVEN. It uses mod (%) operator with 2. If the remainder is 1, then it would be an ODD number otherwise EVEN Number.

 

 

Source Code

using System;

using System.Collections.Generic;

using System.Text;

 

namespace OddEven

{

   class OddOREven

   {

      static bool ReadInteger(out int n)

      {

         string input = System.Console.ReadLine();

         n = 0;

         try

         {

            n = Convert.ToInt32(input);

            return true;

         }

         catch (System.Exception ex)

         {

            System.Console.WriteLine("Error in the input format\n\n");

            return false;

         }

      }

      static void Main(string[] args)

      {

         System.Console.Write("Enter a Number to Check ODD or EVEN: ");

         int number = 0;

         ReadInteger(out number);

 

         if((number % 2) == 0)

            System.Console.WriteLine("{0} is an EVEN number", number);

         else

            System.Console.WriteLine("{0} is an ODD number", number);

      }

   }  

}

Output
