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 .

Switch case statements are used to execute only specific case statements based on the switch expression . If switch expression does not match with any case, default statements are executed by the program.

Advertisements. A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case , and the variable being switched on is checked for each switch case.

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
