Hi,

Is there a way to prevent subclasses from overriding a method in the base class? Essentially, is there an equivalent of a final method like in Java?

No.

It, however, possible to prevent any derivation from a class which, in turn, prevents overriding of any member functions (aka methods).

You might want to look into "c++ Polymorphism".

How can you prevent derivation from a class?
