What are Even Numbers? | Maths Explanation for VB.Net Kids
Hello pupils, what are even numbers?
Answer:
Even numbers are numbers that are divisible by 2.
They include:
Considering how simple and straight-forward even numbers are, writing a Visual Basic code for even numbers
serves as a great way to introduce our Mathematics educational activities for young learners.
Well then, let's see how we can write a programming code to make our computer
list a set of even numbers in the Visual Basic language, between a given range of values.
Bear in mind, we use only a loop and a simple conditional statement for the Visual Basic code.
Create a new Visual Basic Console Project;
call it Arithmetic.vb.
You can rename the module name -- just right-click on the name from the
Solution Explorer panel -- to EvenModule
if you want.
Create a new Visual Basic Class File;
call it EvenNumbers.vb.
Type out the adjoining Visual Basic code for listing even numbers.
So! Visual Basic Fun Practice Exercise - List Even Numbers
As a fun practice exercise, feel free to try out your own boundary values, and see how the Visual Basic code lists the even numbers between those boundary values.
VB.Net Code for Even Numbers - Class File.
Dim first As Integer
Dim last As Integer
Dim result As New List(Of Integer)
' Simulate a constructor
Public Sub _init_(alpha As Integer, omega As Integer)
first = alpha
last = omega
End Sub
' Returns an list Of the desired Set Of even numbers
Public Function prepResult() As List(Of Integer)
' Loop from start to stop and rip out even numbers;
Dim i = 0
For i = first To last
If i Mod 2 = 0 Then ' modulo(%) is explained later
result.Add(i)
End If
Next i
Return result
End Function
End Class
VB.Net Code for Even Numbers - Main Module.
Sub Main()
' Use the even number Class
Dim lower_boundary = 1
Dim upper_boundary = 100
Dim even_list As New EvenNumbers
even_list._init_(lower_boundary, upper_boundary)
Dim answer = even_list.prepResult()
Console.WriteLine("Even numbers between " & lower_boundary & " and " & upper_boundary & " are:")
Console.Write(String.Join(", ", answer))
End Sub
End Module
