Create a variable to hold the current sales count.

Create a variable for the sales target.

Use a while loop to increase sales count until it reaches the target.

Print the final sales count after the loop.

💡 Why This Matters

🌍 Real World

💼 Career

Knowing loops helps automate repetitive tasks, saving time and reducing errors in scripts.

1

Set up initial sales count

Create a variable called salesCount and set it to 0.

PowerShell

# Create a variable called salesCount and set it to 0
# Your code here

Need a hint?

Use = to assign the value 0 to salesCount.

2

Set the sales target

Create a variable called salesTarget and set it to 5.

PowerShell

$salesCount = 0
# Create a variable called salesTarget and set it to 5
# Your code here

Need a hint?

Use = to assign the value 5 to salesTarget.

3

Use a while loop to count sales

Use a while loop with the condition salesCount -lt salesTarget. Inside the loop, increase salesCount by 1.

PowerShell

$salesCount = 0
$salesTarget = 5
# Use a while loop to increase salesCount until it reaches salesTarget
# Your code here

Need a hint?

Use while (condition) { } and inside add salesCount += 1 to increase the count.

4

Print the final sales count

Use Write-Output to print the text "Final sales count: " followed by the value of salesCount.

PowerShell

$salesCount = 0
$salesTarget = 5
while ($salesCount -lt $salesTarget) {
    $salesCount += 1
}
# Print the final sales count
# Your code here

Need a hint?

Use Write-Output "Final sales count: $salesCount" to show the result.
