Check Leap Year using C#
Here is a simple code example in C# to Check Whether the Entered Year is a Leap Year or Not.
public static void Main() { int inputYear; Console.WriteLine("Enter Any Year To Check Whether the Entered Year is a Leap Year or Not"); AnyYear=int.Parse(Console.ReadLine()); if (inputYear % 400 == 0 || (inputYear % 4 == 0 && inputYear % 100 != 0 )) { Console.WriteLine("Is Leap Year : {0}",inputYear); } else { Console.WriteLine("Not a Leap Year : {0}",inputYear); } Console.ReadLine(); }
Output:
Enter Any Year To Check Whether the Entered Year is a Leap Year or Not
1999
Not a Leap Year : 1999
Code explanation
We can find the leap year in C# using the below algorithm. This algorithm determines Whether the Entered Year is a Leap Year or Not
if (the year isn’t divided by 4) then (it is a typical(common) year)
else if (the year isn’t divided by 100) then (it is a leap year)
else if (the year isn’t divided by 400) then (Typical(common) year)
else (leap year)
