I thought the default case only runs if no other cases match, so yeah, I guess it should print "End" in this situation.

I'm not entirely sure, but I feel like it might print something else if there's a fall-through, but in this case, it seems like it won't.

I remember practicing a similar question, and I believe it should print "End" because none of the cases match.

I think the switch statement will just skip all cases since `i` is 5, so it might go to the default case.

Alright, I've got this. The variable 'i' is set to 5, and the switch statement checks the value of 'i'. Since 5 doesn't match any of the case values, the default case will be executed, which prints "End". I'm confident that's the correct answer.

Hmm, I'm not entirely sure about this one. The switch statement looks straightforward, but I'm wondering if there's some edge case or nuance I'm missing. I'll need to carefully re-read the code and think it through before answering.

Okay, let me break this down step-by-step. The variable 'i' is set to 5, and the switch statement checks the value of 'i'. Since 5 doesn't match any of the case values (1, 2, or 3), the default case will be executed, which prints "End". I think I've got it now.

I'm a bit confused here. The switch statement has cases for 1, 2, and 3, but the variable 'i' is set to 5. Does that mean the default case will be executed, or is there something I'm missing?

Hmm, let me think this through. The variable 'i' is initialized to 5, so the default case should be executed, which prints "End". I'm pretty confident that's the correct answer.

The correct answer is C. The code will print 'End' because the value of 'i' is 5, which doesn't match any of the case statements, so it will execute the default case.

I believe it will print: End as well, since the default case will be executed when no other case matches.

Haha, I bet the answer is D. It will print 'Helloworld' because the code is clearly broken and will do something unexpected. That's what happens when you write spaghetti code!

I think the answer is B. The code will print 'world' because the value of 'i' is 5, which matches the case 2 statement.

The answer is C. The code will print 'End' because the value of 'i' is 5, which doesn't match any of the case statements, so it will execute the default case.
