How do I use enums in C++ classes?

Enums in C++ allow you to define a set of named integral constants. You can use them within classes to represent a group of related values.

Can you show me an example of an enum in a class?

Sure! Here's a simple example:

class TrafficLight {
public:
    enum Color { RED, YELLOW, GREEN };
    Color currentColor;

    void setColor(Color color) {
        currentColor = color;
    }
};

What are the benefits of using enums in classes?

Using enums improves code readability and maintainability by providing meaningful names for sets of related constants, reducing errors.

Can enums be used with switch statements?

Yes, enums work perfectly with switch statements, allowing you to handle different enum values easily.
