Listing Odd Numbers Using Visual Basic
This tutorial explains how to list odd numbers using Visual Basic in a simple and beginner-friendly way. It is designed for students and learners who are new to programming and want to understand how odd numbers can be generated using basic Visual Basic logic.
By the end of this lesson, you will know how to generate odd numbers in Visual Basic, use loops effectively, and apply simple conditions to filter numbers.
What Are Odd Numbers? | Maths Explanation for Visual Basic Kids
Odd numbers are whole numbers that are not divisible by 2. Examples include 1, 3, 5, 7, and 9. In mathematics, an odd number always leaves a remainder of 1 when divided by 2.
Understanding odd numbers is an important part of primary mathematics, and Visual Basic provides a practical way to explore this concept using code.
How to Generate Odd Numbers in Visual Basic
To generate odd numbers in Visual Basic, we use a loop to go through a range of numbers and a condition to check whether each number is odd.
A number is considered odd if:
number % 2 !== 0
This condition checks whether the remainder after dividing by 2 is not zero.
Visual Basic Odd Number Program (Beginner Example)
The following example shows a simple Visual Basic odd number program. It lists odd numbers within a given range and displays them on the page.
This type of example is commonly used in Visual Basic beginner tutorials and helps students learn both maths concepts and programming basics at the same time.
Create a new Visual Basic Class File;
Call it oddNumbers.vb.
Optionally, Create a new Visual Basic Module File;
Call it OddModule.vb.
Type out the adjoining Visual Basic (VB.Net) code for listing odd numbers.
Code for Odd Number List with User Input in Visual Basic (VB.Net)
For a little more flexibility, let's add an input form to our VB.Net code for odd numbers.
All we need is a way to ask the user for input.
For this purpose, we'll use the Console.ReadLine()
VB.Net library function.
Using a Loop to Display Odd Numbers in Visual Basic
A loop allows Visual Basic to repeat an action multiple times. In this case, the loop checks each number in a range and displays only the odd ones.
This approach demonstrates:
- How to use a loop in Visual Basic
- How to apply conditions
- How to list odd numbers with Visual Basic clearly and efficiently
It is an excellent example for learners studying Visual Basic maths code for the first time.
We have used a function here.
A function is a chunk of code that is executed when it is called upon,
such as when an event occurs.

So! Visual Basic Fun Practice Exercise - List Odd Numbers
As a fun practice exercise, feel free to try out your own boundary values, and see how the Visual Basic code lists the odd numbers between those boundary values.
VB.Net Code for Odd 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
