Lesson outline
Introduction to Loop Control
The break and continue statements provide fine-grained control over loop execution.
break exits a loop immediately, while continue skips the rest of the current iteration and jumps to the next cycle.
break Statement
The break statement ends the loop as soon as it is encountered, regardless of the loop condition.
continue Statement
The continue statement skips the remaining code in the current iteration and starts the next loop cycle.
Nested Loop Control
break and continue only affect the innermost loop in which they appear.
Practical Examples
Common use cases of break and continue include:
| Scenario | Statement | Reason |
|---|---|---|
| Input validation | break | Exit loop once valid input is received |
| Search algorithm | break | Stop searching when the target is found |
| Data filtering | continue | Skip unwanted or invalid records |
| Menu systems | break | Exit a loop-based menu selection |
Best Practices
- Use break and continue sparingly; overuse can reduce readability.
- Prefer clear loop conditions instead of multiple breaks.
- Comment control flows that are not obvious.
- When affecting outer loops, consider using flags or restructuring logic.
- Avoid mixing break/continue with overly complex loop logic.
