How can I use advanced switch statements in C++?

In C++, advanced switch statements can include multiple case labels, fall-through behavior, and even expressions. Would you like an example?

Yes, please provide an example of using multiple case labels.

Sure! Here's an example:

switch (value) {
    case 1:
    case 2:
        std::cout << "Value is 1 or 2";
        break;
    case 3:
        std::cout << "Value is 3";
        break;
    default:
        std::cout << "Value is something else";
}

This will output "Value is 1 or 2" if the value is either 1 or 2.

What about using expressions in switch statements?

In C++, switch statements can only evaluate integral types or enumeration constants. However, you can use expressions that evaluate to these types. For example:

int x = 5;

switch (x * 2) {
    case 10:
        std::cout << "x is 5";
        break;
    default:
        std::cout << "x is not 5";
}

This will output "x is 5".
