Visual Basic create loop for counting even numbers

Visual Basic create loop for counting even numbers

Certainly! You can create a loop in Visual Basic (VB.NET) to count even numbers within a specified range. Here's an example using a For loop:

Module Module1 Sub Main() ' Define the range Dim startNumber As Integer = 1 Dim endNumber As Integer = 10 ' Initialize a counter for even numbers Dim evenCount As Integer = 0 ' Loop through the numbers in the range For i As Integer = startNumber To endNumber ' Check if the current number is even If i Mod 2 = 0 Then ' Increment the counter for even numbers evenCount += 1 End If Next ' Display the result Console.WriteLine($"Number of even numbers between {startNumber} and {endNumber}: {evenCount}") ' Pause to see the result Console.ReadLine() End Sub End Module

This example counts the number of even numbers between startNumber and endNumber. Adjust the values of startNumber and endNumber to define the range you are interested in.

The condition i Mod 2 = 0 checks if i is divisible by 2 (i.e., an even number). The evenCount variable is incremented each time an even number is encountered.

When you run this program, it will output the count of even numbers in the specified range.
