Why default is used in C?

The break command allows you to terminate and exit a loop (that is, do , for , and while ) or switch command from any point other than the logical end .

The default statement is executed if no case constant-expression value is equal to the value of expression . If there’s no default statement, and no case match is found, none of the statements in the switch body get executed. There can be at most one default statement.3 Ağu 2021
