⚠ Common exam trap
The trap is that candidates often forget that switch cases fall through to subsequent cases unless a break statement is used, leading them to think only '1' is printed.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
123
123. This output results from a switch statement with fall-through behavior. The matching case prints '1', but because there is no break, execution continues to the next case printing '2', and then to the next printing '3' until a break is encountered or the switch ends. Thus, '123' is printed.
