Secondly, can cases in switch statement have conditions? A statement in the switch block can be labeled with one or more case or default labels.

Similarly, you may ask, what are the rules for switch statement?
Rules for switch statement:
- An expression must always execute to a result.
- Case labels must be constants and unique.
- Case labels must end with a colon ( : ).

- You cannot use the same constant in two different cases.
- We cannot use the relational expression in case.
