In a switch statement, if the break keyword is not used, it results in _________.
- An error
- A warning
- Fall-through behavior
- A timeout
In a switch statement, if the break keyword is not used, it results in fall-through behavior. Fall-through means that once a case is matched and its code block is executed, the program continues to execute the code blocks of subsequent cases, even if they don't match. This can lead to unintended behavior and is usually controlled by using the break keyword.
