How do I use switch statements in C++?

In C++, a switch statement allows you to execute different parts of code based on the value of a variable. Here's a basic structure:

switch(variable) {
    case value1:
        // code to execute if variable == value1
        break;
    case value2:
        // code to execute if variable == value2
        break;
    default:
        // code to execute if variable doesn't match any case
}

Can you give me an example of a switch statement?

Sure! Here's an example that checks the day of the week:

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";
}

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.

Are there any limitations to using switch statements?

Yes, switch statements can only evaluate integral types (like int or char) and cannot handle ranges or conditions like if statements.
