The Keyword Default
To specify the code to execute if there is no case match, you can use default
keyword in switch statement. For example, the coffee machine has a list of types of coffee by its number (from 1 to 3). If you want to choose one, just type its number. But there is a huge amount of numbers that users can type by mistake. Here we can use the default
keyword:
// Declare and assign the variable
int number;
cin >> number;
// Choose coffee
switch (number) {
case 1:
cout << "Espresso";
break;
case 2:
cout << "Latte";
break;
case 3:
cout << "Cappuccino";
break;
default:
cout << "Your number isn't valid. Please, try again.";
}
The default
statement executes the code when the non of statements are true.
The
default
statement must be at the end of the switch.
