Can two classes be combined into a common derived class?

Question

OOP

I study OOP, specifically now - inheritance. I got the general concept, but the question is about practical application.
Let's say there is a base class - Man. He has two derivatives - the driver and the military.
The essence of the question: is it possible to combine two such subclasses, inside a superclass? Is this implementable in C#, and if so, how much (if at all) will it complicate further support?

Answer 1

He asked, he answered.
Yes, in theory you can. This is called multiple inheritance.
Multiple inheritance is a potential source of errors that can arise from having the same method names in ancestors. In languages ​​that are positioned as the heirs of C ++ (Java, C # and others), it was decided to abandon multiple inheritance in favor of interfaces.
