C Sharp ( C# ) If..Else Statement

If..Else Statement is used whenever a particular condition is true, a certain set of tasks needs to be done and if the condition isn't true then another set of tasks are performed.

Syntax :
if (condition)
    {
        set of tasks or statements; (Set 1)
    }
else
    {
        set of tasks or statements; (Set 2)
    }

If the condition is satisfied, then the Set 1 statements are executed. If the condition fails, then the Set 2 statements are executed.

Example : Find if a value is even or odd. If even then print a statement, if not then print another statement.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace ConsoleApplication

{

    class Program

    {

        static void Main(string[] args)

        {

            int number = Convert.ToInt32(Console.ReadLine());

            int value = number % 2; //If the remainder is zero its an even number.

            if (value == 0)

            {

                Console.WriteLine("The number {0} is an even number.", number);

            }

            else

            {

                Console.WriteLine("The number {0} is an odd number.", number);

            }

            Console.ReadLine();

        }

    }

}
