Break and continue in PowerShell - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the break statement do in a PowerShell loop?

The break statement immediately stops the entire loop and exits it, continuing with the code after the loop.

What is the purpose of the continue statement in PowerShell loops?

The continue statement skips the rest of the current loop iteration and moves to the next iteration of the loop.

How does break differ from continue in PowerShell loops?

break stops the whole loop immediately, while continue skips only the current iteration and continues looping.

Example: What will this PowerShell code output?<br>

for ($i=1; $i -le 5; $i++) { if ($i -eq 3) { break } Write-Output $i }

It will output:<br>1<br>2<br>Because when $i equals 3, break stops the loop immediately.

What happens when break is used inside a PowerShell loop?

A Nothing happens, loop runs normally.

B The current iteration is skipped, loop continues.

C The loop restarts from the beginning.

D The loop stops immediately and exits.

break stops the entire loop immediately and exits it.

What does continue do in a PowerShell loop?

A Stops the loop completely.

B Skips the rest of the current iteration and continues with the next.

C Restarts the loop from the first iteration.

D Ends the script.

continue skips the rest of the current loop iteration and moves to the next one.

Which statement would you use to skip printing number 3 but continue the loop in PowerShell?

A continue

B exit

C break

D stop

continue skips the current iteration but keeps the loop running.

If you want to stop a loop as soon as a condition is met, which statement is best?

A break

B continue

C return

D exit

break immediately stops the loop when the condition is met.

What will this code output?<br>

for ($i=1; $i -le 4; $i++) { if ($i -eq 2) { continue } Write-Output $i }

A 1 2 3 4

B 2 3 4

C 1 3 4

D 1 2 4

When $i equals 2, continue skips printing 2, so output is 1 3 4.

Explain in your own words how break and continue control the flow inside PowerShell loops.

Think about what happens when you want to stop everything vs just skip one step.

Write a simple PowerShell loop that prints numbers 1 to 5 but skips number 3 using continue.

Use an if statement inside the loop to check for 3 and skip it.
