Wait, are we sure there's no other error?

Totally agree, that's a major error!

The variable 'i' is undeclared, that's a big issue.

Isn't 'c' supposed to be used in the switch?

I think the switch statement is fine, just fix 'i'.

I feel like I’ve seen a similar question before, and it was about undeclared identifiers, so maybe that's the error here too.

I’m a bit confused; I thought 'continue' was only used in loops, so I don’t think that’s the problem here.

I remember something about switch statements, but I’m not sure if there’s an error with the case labels.
MA

I think there’s an issue with the variable 'i' since it’s not declared anywhere in the program.

I'm feeling pretty confident about this one. The error is clearly the use of the undeclared variable 'i' in the switch statement. I'll make a note to always double-check variable declarations when analyzing code.

Ah, I see the problem now. The variable 'i' is not defined, so the switch statement won't work as expected. I'll make sure to check for any undeclared variables when reviewing code on the exam.

Okay, I think I've got it. The issue is that the variable 'i' is used in the switch statement, but it's never declared or initialized. That's gotta be the error they're looking for.

Uh oh, I'm a bit confused here. The question mentions an error, but I'm not sure I see one right away. I'll have to double-check the syntax and variable declarations.

Hmm, this looks tricky. I'll need to carefully read through the code and think about the use of the switch statement and the variable 'i'.

I think the error is in the line 'switch(i)' because 'i' is not declared anywhere in the program.

B) Use of undeclared identifier 'i'

I'd say it's D. The 'break' statement inside the 'default' case is not necessary and could be considered an illegal use of it.

B) Use of undeclared identifier 'i'

A) No Error

Definitely B. The variable 'i' is not declared anywhere in the code, so it's a clear case of using an undeclared identifier.
JA

A) No Error
TO

Yeah, definitely B. 'i' is nowhere to be found in the code.
