Can 'return' statements be used in case statements without a default case?

Yes, without any complaints
Yes, but with compiler complaints
No, it's not allowed
It depends on the enum

The correct answer is: Yes, but with compiler complaints

The return statement can be used in case statements, even without a default case, but the compiler will issue a warning if the case statements do not cover all possible values. This is because without a default case, there is a possibility that not all values will be accounted for and the program may not function correctly. Therefore, it is considered good practice to have a default case in case statements. Answer B is correct because although the return statement can be used, the compiler will issue a warning. Options A, C, and D do not accurately describe the use of return statements in case statements. Option A is incorrect because although the return statement can be used, the compiler may still issue a warning. Option C is incorrect because return statements can be used in case statements. Option D is incorrect because whether or not the return statement can be used depends on the situation and not just the enum.
