Switch Statement
Learn about the switch statement in C++ to perform conditional operations.
We'll cover the following...
When installing software, you might come across a statement telling you that this installation is taking some amount of memory. You are then asked if you want to continue with the installation process and told to enter y or Y to continue or x or X to quit. This scenario can be implemented using an if else block as shown below:
if(ans == ‘Y’ || ans == ‘y’)// continue the installationelse if(ans == ‘X’ || ans == ‘x’)// terminate the installationelse// invalid input terminate
Installing software condition
Similar to this scenario, whenever you are checking for an exact value and not a range, you can also use the switch-case statement.
The switch-case construct
This tests an input variable for equality with any number of cases and then executes the corresponding code. The workflow that works in this case is as follows:
The switch statement evaluates a variable. ...
