While and Do-While loops in PowerShell - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a while loop that prints numbers from 1 to 3.

PowerShell

$i = 1
while ($i [1] 4) {
    Write-Output $i
    $i++
}

Drag options to blanks, or click blank then click option'

C-eq

💡 Hint

Common Mistakes

Using -gt will make the loop never run because 1 is not greater than 4.

Using -eq will only run if $i equals 4, which is not the intended condition.

The -lt operator means 'less than'. The loop runs while $i is less than 4.

Complete the code to create a do-while loop that prints numbers from 1 to 3.

PowerShell

$i = 1
do {
    Write-Output $i
    $i++
} while ($i [1] 4)

💡 Hint

Common Mistakes

Using -gt will cause the loop to never run because 1 is not greater than 4.

Using -eq will only run if $i equals 4, which is not the intended condition.

The loop runs while $i is less than 4, so it prints 1, 2, and 3.

3fill in blank

hard

Fix the error in the while loop condition to count down from 5 to 1.

PowerShell

$i = 5
while ($i [1] 0) {
    Write-Output $i
    $i--
}

Drag options to blanks, or click blank then click option'

C-lt

💡 Hint

Common Mistakes

Using -lt will cause the loop to never run because 5 is not less than 0.

Using -eq will only run if $i equals 0, which is not the intended condition.

The loop should run while $i is greater than 0 to count down from 5 to 1.

4fill in blank

hard

Fill both blanks to create a while loop that prints even numbers from 2 to 10.

PowerShell

$i = 2
while ($i [1] 10) {
    Write-Output $i
    $i [2] 2
}

Drag options to blanks, or click blank then click option'

A-le

C-lt

D-=

💡 Hint

Common Mistakes

Using -lt excludes 10, so 10 won't be printed.

Using -= will subtract 2, causing an infinite loop.

The loop runs while $i is less than or equal to 10, and increments $i by 2 each time.

5fill in blank

hard

Fill all three blanks to create a do-while loop that prints numbers from 10 down to 1.

PowerShell

$i = [1]
do {
    Write-Output $i
    $i [2] 1
} while ($i [3] 0)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Starting at 1 will not count down from 10.

Using += will increase $i causing an infinite loop.

Using -lt or -le in the condition will cause the loop to stop immediately.

Start $i at 10, subtract 1 each time, and continue while $i is greater than 0.
