P2C2: Write a program in C Sharp to check whether a number entered by a user is even or odd.

//Using if else statement

using System;

public class Program_Even_Odd
{
   public static void Main()
    {
        int num;

        Console.WriteLine("Enter any number: ");
        num = Convert.ToInt32(Console.ReadLine());

        if (num % 2 == 0)
            Console.WriteLine("\n{0} is an Even number", num);
        else
            Console.WriteLine("\n{0} is an Odd number", num);
                 
        Console.WriteLine("\nPress any key to exit...");
        Console.ReadLine();

    }

//Using case statement

using System;

public class Program_Even_Odd

{

   public static void Main()

    {

        int num, ans;

        Console.WriteLine("Enter any number: ");

        num = Convert.ToInt32(Console.ReadLine());

       ans = (num % 2);

       switch (ans)

       { 

           case 0:

               Console.WriteLine("\n{0} is an Even number", num);

               break;

           case 1:

               Console.WriteLine("\n{0} is an Odd number", num);

               break;

           default:

               Console.WriteLine("Invalid Entry");

               break;

       }

                   

        Console.WriteLine("\nPress any key to exit...");

        Console.ReadLine();

    }

}

OUTPUT:

Enter any number:
55

55 is an Odd number
