5. Adding Two Numbers in VB.NET

Now that you have a basic understanding of the environment and syntax, let’s dive into adding two numbers.

Step-by-Step Guide

Follow these steps to create a simple program that adds two numbers:

  1. Open your VB.NET project in Visual Studio.
  2. In the Module1.vb file, write the following code:

Module Module1
    Sub Main()
        Dim num1 As Integer
        Dim num2 As Integer
        Dim sum As Integer

        Console.Write("Enter the first number: ")
        num1 = Convert.ToInt32(Console.ReadLine())

        Console.Write("Enter the second number: ")
        num2 = Convert.ToInt32(Console.ReadLine())

        sum = num1 + num2

        Console.WriteLine("The sum of {0} and {1} is {2}.", num1, num2, sum)
        Console.ReadLine()
    End Sub
End Module
