C++ Introduction

Switch StatementSwitch Statement

The switch-case construct allows you to compare the result of an expression against a set of predefined values. Structure of switch-case:

cpp

main.cpp

  • 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.

But the switch statement has one caveat. We intentionally remove the break statement:

cpp

main.cpp

Without 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 switch block.
