What are some examples of switch case statements in C++?

In C++, a switch case statement allows you to execute different parts of code based on the value of a variable. For example:

int number = 2;
switch (number) {
    case 1:
        cout << "Number is 1";
        break;
    case 2:
        cout << "Number is 2";
        break;
    default:
        cout << "Number is not 1 or 2";
}

Can you explain how the break statement works in a switch case?

The break statement in a switch case is used to terminate a case in the switch block. Without it, the program will continue executing the subsequent cases until it hits a break or the end of the switch block. This is known as 'fall-through' behavior.

Are there any limitations to using switch case in C++?

Yes, switch case statements can only evaluate integral types like int, char, or enum. They cannot evaluate floating-point numbers or strings.

Can you provide a more complex example with multiple cases?

Sure! Here's a more complex example:

char grade = 'B';
switch (grade) {
    case 'A':
        cout << "Excellent!";
        break;
    case 'B':
        cout << "Well done!";
        break;
    case 'C':
        cout << "Good job!";
        break;
    default:
        cout << "Grade not recognized.";
}
