Program to Check Leap Year - (C# Basic Programs)

A leap year is a year that is divisible by 4, except for years that are divisible by 100 but not divisible by 400. In this tutorial, we will discuss a C# program to check if a given year is a leap year or not.

Syntax

The syntax for checking whether a year is a leap year or not in C# is as follows:

if ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0)) {
    Console.WriteLine(year + " is a leap year");
}
else {
    Console.WriteLine(year + " is not a leap year");
}

Example

using System;

namespace LeapYearProgram
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Enter a year: ");
            int year = int.Parse(Console.ReadLine());

            if ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0)) {
                Console.WriteLine(year + " is a leap year");
            }
            else {
                Console.WriteLine(year + " is not a leap year");
            }

            Console.ReadLine();
        }
    }
}

Output

Enter a year: 2024
2024 is a leap year

Explanation

The program prompts the user to enter the year they want to check. The program then evaluates whether the given year is a leap year or not. If the given year is divisible by 4 and not divisible by 100, or is divisible by 400, the program will output that the year is a leap year. If not, the program will output that the year is not a leap year.

Use

Checking whether a year is a leap year or not in C# is a basic programming skill that can be used in various applications. It helps in calculations related to time, dates and financial applications where interest is paid on a yearly basis and the number of days in a year is important.

Summary

In this tutorial, we discussed a C# program to check whether a given year is a leap year or not. We presented the syntax, example, explanation, and use of C# programming to check leap year. By practicing these exercises, programmers can improve their problem-solving and C# programming skills.
