What I meant is that OO is a way of looking at things to ensure good design. If you need to do inheritance or polymorphism or encapsulation, you *design* your program that way, and you can *implement* it in any language, even a non-OO language. Instead of using language features, you can impose OO guidelines/constraints in the *way* you write your code. So the language doesn't have to do the inheritance / polymorphism / encapsulation, your design does it.

Hence you don't need the overheads of vtables or other OO features in C++.

It certainly is possible: I once had to do a project in C, but the design was totally OO; I managed to do well enough without C++. Also the fact that the compiler in question implements C++ as a preprocessor over C, supports my point of view.

I hope I got my meaning across...
