Expert Solution
Step 1

Switch case:

Switch statement is operated based on the expression of the switch.

Switch statement has different cases based on the expression on switch corresponding case is executed.

If all cases fail then the then the default case is executed .

default case is written at end of the cases.

If the particular case is true then there is no break statement, in that situation all cases (including default) after that case is executed it stops until there is a break statement executed.
