What is a leap year and how to write a visual basic program to check leap year? before write the code let’s understand the leap year.
What is a leap year?
A year that has 366 days is called a leap year. It means an extra day in the year which will be 29 Feb and it comes in every 4 years.
As a programming logic, we can say A year which is divide by 4, 1oo and 400 is called a leap year.
Visual basic program to check leap year or not
In the below code will solve the leap year problem using visual basic. It will take a year as user input and check the year is divisible 4, 100 and 400. If it is divisible then it will print “This is a leap year” or If it is not then it will pint “This is not a leap year”.
Module Module1 Sub Main() Console.WriteLine("Enter a year...") Dim x, y, z, year 'Read a year.......... year = Console.ReadLine() x = year Mod 4 y = year Mod 100 z = year Mod 400 If ((x = 0 And Not (y = 0)) Or z = 0) Then Console.WriteLine("This is a leap year") Else Console.WriteLine("This is not a leap year") End If Console.ReadLine() End Sub End Module
Check leap year in visual basic using forms
This is the example 2 that is using Visual basic form or you can say a visual basic application. that going to implement the same logic but this time using forms.
It will take a year as input check the condition and print output message as a result.
Public Class Form1 Dim x, y, z, year Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Sum.Click year = TextBox1.Text x = year Mod 4 y = year Mod 100 z = year Mod 400 If ((x = 0 And Not (y = 0)) Or z = 0) Then Label2.Text = "This is a leap year" Else Label2.Text = "This is not a leap year" End If End Sub End Class
