Answer 8

The pseudo-code fragment follows:

Syntax of a switch-case statement switch(expression){ case constant:sequence of optional statements break; //optionalcase constant: sequence of optional statementsbreak; //optional .. .default //optional sequence of optional statements}

An expression is tested against a series of unique integer constants. If a match is found, the sequence of optional statements associated with thematching constant is executed. Execution of statements continues until an optional break is encountered. When break is encountered, execution of the switch statement is terminated and control is passed to the next statement following the switch statement.

If no match is found and the optional default keyword along with a sequence of optional statements has been provided, those statements willbe executed.
