In this lesson, we will discuss the C++ switch statement for control flow and exactly how you could use a switch statement. We will also cover some...
So stating there is no default in a switch is somewhat wrong. They could define a switch to mean: select a block, run it and that's it. The case statement could be extended to accept multiple parameters, event ranges. The goto shouldn't be there; extract the common code to a method...

The break statement Thebreakstatement terminates the execution of the nearest enclosing do, for, switch, or while statement in which it appears. The execution of the program passes to the statement that follows the terminated statement. C break with while ...
C++C++ StatementC++ Condition Thebreakstatement in C and C++ is used to stop a loop from iterating if the required condition is met within the code blocks of theswitchstatement. If thebreakstatement is not used, the program will continue to execute until the end of theswitchstatement is reac...
