Answer 2

The default case is optional in a switch case construct.

• Whenever the test-expression value does not fit any of the cases within the switch, the default is executed.
• Otherwise, in the switch, it is not necessary to write default. The default case also does not need a break.
• There may be an optional default case for a switch argument, which must appear at the end of the switch. If neither case is valid, the default case may be used to perform a mission.
