No, you can still have classes and attributes, you just don't build a full inheritance tree. Again, inheritance is one of MANY tools, and only in the most basic of OO implementations is inheritance the key to the entire puzzle.
Comment on Re: Re: inheritance and object creation
Well, just four classes with obvious relationships is
pretty basic to me. And your solution is to not have
any inheritance at all.
Sure, not having any inheritance at all is a solution
to "should we use multiple inheritance". I don't think
that gives you any of one of the prime benefits of OO programming (code reuse) though.
