For loop in PowerShell - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print numbers from 1 to 5 using a for loop.

PowerShell

for ($i = 1; $i -le 5; $i[1]) { Write-Output $i }

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

💡 Hint

Common Mistakes

Using -- decreases the counter, causing an infinite loop.

Using += without a number is incomplete syntax.

In PowerShell, to increase the loop counter by 1, use ++ after the variable.

2fill in blank

medium

Complete the code to loop through numbers 0 to 4 and print each.

PowerShell

for ($num = 0; $num [1] 5; $num++) { Write-Output $num }

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

B-gt

C-eq

D-lt

💡 Hint

Common Mistakes

Using '-gt' would never run the loop because 0 is not greater than 5.

Using '-eq' would only run when $num equals 5, which is not the loop condition.

The '-lt' operator means 'less than', so the loop runs while $num is less than 5.

3fill in blank

hard

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

PowerShell

for ($i = 5; $i -ge 1; $i[1]) { Write-Output $i }

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

C+=

D-=

💡 Hint

Common Mistakes

Using ++ increases the counter, causing an infinite loop.

Using -= without a number is incomplete syntax.

To count down, decrease the counter by 1 each time using --.

4fill in blank

hard

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

PowerShell

for ($i = [1]; $i [2] 10; $i += 2) { Write-Output $i }

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

A2

B-lt

C-le

D0

Attempts:

💡 Hint

Common Mistakes

Starting at 0 would include zero, which is not an even number in this context.

Using '-lt' excludes 10 from the output.

Start at 2 and loop while $i is less than or equal to 10 to include 10.

5fill in blank

hard

Fill all three blanks to create a loop that prints squares of numbers from 1 to 5.

PowerShell

for ($num = [1]; $num [2] 5; $num [3]) { Write-Output ($num * $num) }

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

A1

B-le

C++

D0

Attempts:

💡 Hint

Common Mistakes

Starting at 0 would print 0 squared, which may not be desired.

Using '-lt' excludes 5 from the output.

Start at 1, loop while less than or equal to 5, and increment by 1 each time.
