Break and continue behavior in Swift - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the break statement do inside a loop in Swift?

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

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

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

In Swift, what happens if you use break inside a nested loop?

The break statement only exits the innermost loop where it is called, not all outer loops.

intermediate

Can continue be used in a switch statement in Swift?

No, <code>continue</code> is used in loops, not in <code>switch</code> statements. To skip cases in <code>switch</code>, you use <code>fallthrough</code> or just let the case end.

How does break differ from continue in Swift loops?

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

What will happen if a break statement is executed inside a Swift for loop?

A The loop restarts from the beginning.

B The current iteration is skipped, and the loop continues.

C The loop stops immediately and exits.

D Nothing, the loop continues normally.

The break statement immediately stops the loop and exits it.

What does the continue statement do in a Swift loop?

A Stops the entire loop.

B Skips the rest of the current iteration and moves to the next iteration.

C Exits the function.

D Restarts the loop from the first iteration.

continue skips the rest of the current iteration and proceeds with the next one.

If break is used inside a nested loop, which loop does it exit?

A Only the innermost loop where <code>break</code> is called.

B All loops at once.

C The outermost loop.

D It causes an error.

break exits only the innermost loop it is inside.

Can continue be used to skip a case in a Swift switch statement?

A Yes, it skips the case.

B No, you must use <code>break</code> instead.

C Yes, but only in <code>switch</code> with loops.

D No, <code>continue</code> is only for loops.

continue is used only in loops, not in switch statements.

Which statement best describes the difference between break and continue in Swift loops?

A <code>break</code> stops the loop; <code>continue</code> skips current iteration.

B <code>break</code> skips current iteration; <code>continue</code> stops the loop.

C Both stop the loop immediately.

D Both skip the current iteration.

break stops the loop; continue skips the current iteration and continues.

Explain how break and continue behave inside Swift loops and how they differ.

Think about what happens to the loop after each statement runs.
