The switch statement evaluates the expression of the switch statement and moves the execution order to a case statement with an expression matching the value.
The case statement specifies an expression that means a case and ends with a colon. And then position the doors to execute.
If there is no case statement with an expression that matches the expression of the switch statement, the execution order moves to the default statement.

The default option is literally optional.
