Leap Year:

Leap year is a year in which the day is 366 instead of 365 because there are 29 days in February month. We can find all the leap year by using the following C# program.

Program:

using System;					

public class Program

{

 public static void Main()

 {

int num=2018, i;

  if((num%400==0)||(num%4==0 && num%100!=0))

  {

  Console.WriteLine('is Leap Year');

  }else 

  {

  Console.WriteLine('not Leap Year');

  }

}

}

Output:     not Leap Year

Program for Taking input a year by user to check that is Leap year or not.

using System;

public class Program

{

 public static void Main()

 {

  int num;

  Console.WriteLine('Enter an year to check whether is Leap year or not');

  num=int.Parse(Console.ReadLine());

  if(num%4==0)

  {

   if(num%100!=0)

   {

    if(num%400==0)

    {

      Console.WriteLine(num+' is a Leap year');

    }else

     Console.WriteLine(num+' is a Leap year');

   }else

   {

   Console.WriteLine(num+' not a leap year');

   }

  }else 

  {

  Console.WriteLine('not a leap year');

  }

 }

}

Output:

Enter an year to check whether is Leap year or not

2020

2020 is a Leap year
