A switch statement executes logic, dependent on the value of a given expression (parameter). The types of values a switch statement operates on can be boolean, enum, integral types, and strings. Each switch statement can contain any number of case statements, but no two case constants within the same switch statement can have the same value. Each case statement defines a value to compare against the original expression. You may also include a default label following all other case statements. If none of the other choices match, then the default choice is taken and its statements are executed. If there is no default label, control is transferred outside the switch.
