Just getting into these and have a few questions.
First, it looks to me like when you're creating these, you declare as pure virtual methods (with virtual ... = 0;) exactly those methods that you insist be redefined in every derived class, right?
And you of course declare just as good ole public methods in the abstract class those that should apply to every derived class and hence don't need to be repeated (?).
Well, every derived class that is to be instantiated. You can always have an abstract class inherit from another abstract class in which case some of the pure virtual functions in the base class may not be overridden.Quote:

Correct. Of course the functions don't need to be public...Quote:

Cool, thanks! ... both for clarifying the rule and pointing out the exceptions to be aware of.
