What is the scope of enums in C++?

What is the scope of enums in C++?

In C++, the scope of an enum is determined by where it is defined. If defined inside a class, its scope is limited to that class.

Can you give an example of an enum defined inside a class?

Sure! Here's an example:

class MyClass {
public:
    enum Color { RED, GREEN, BLUE };
};

In this case, Color is scoped to MyClass.

What about enums defined outside of any class?

Enums defined outside of any class have global scope, meaning they can be accessed from anywhere in the code after their declaration.

Are there any best practices for using enums in C++?

Yes, it's best to use scoped enums (enum class) to avoid name clashes and to improve type safety.
