What are the scoping rules for enums in C++?

What are the scoping rules for enums in C++?

In C++, enums have their own scope. This means that the enumerators are scoped to the enum type itself.

Can you explain what that means with an example?

Sure! For instance, if you have an enum called Color with values Red, Green, and Blue, you can access them as Color::Red, Color::Green, and Color::Blue.

What happens if I define an enum inside a class?

If you define an enum inside a class, the enumerators will be scoped to that class, and you'll need to use ClassName::Enumerator to access them.

Are there any differences between scoped and unscoped enums?

Yes, scoped enums (enum class) do not implicitly convert to integers and require the scope to access enumerators, while unscoped enums do.
