How do I use switch statements in C++?

Switch statements in C++ allow you to execute different parts of code based on the value of a variable. Would you like a basic example?

Yes, please provide a simple example.

Sure! Here's a basic example:

int main() {
    int day = 3;
    switch(day) {
        case 1:
            std::cout << "Monday";
            break;
        case 2:
            std::cout << "Tuesday";
            break;
        case 3:
            std::cout << "Wednesday";
            break;
        default:
            std::cout << "Invalid day";
    }
    return 0;
}

This code will output "Wednesday".

What happens if I forget the break statement?

If you forget the break statement, the program will continue executing the subsequent cases until it hits a break or the end of the switch. This is called 'fall-through' behavior.

Can I use switch statements with strings?

No, C++ switch statements only work with integral types (like int or char). For strings, you would typically use if-else statements.
