Introduction to C++
The switch-case construct allows you to compare the result of an expression against a set of predefined values. Kind of a hybrid of
Structure of switch-case:
break - statement means an exit from a block of code.
default - is an optional part but a useful one. This part will be executed if none of the cases doesn’t fit.
In our case, we check the
variable, if it is equal to
5, then the corresponding text will be displayed and, using the
break statement, the program flow will leave the entire
switch-case construction, and there will be no processing of other cases.
switch-case statement has one caveat. We intentionally remove the
break command, the program flow will ignore all the following checks and simply execute the commands of the following cases until it encounters the
break statement or the end of the entire
