Suggest me something

[MrD.]

He's saying he wants to discuss C++.

Discuss C++, ok.

Here's a question: Give me one example of how it is possible in C++ to call a pure-virtual member function (something that you should not be able to do, and that dong directly in an obvious way would cause a compiler error; by the way, calling a pure-virtual function is a bad idea and results in a crash, it's just fun to know the gotcha's of a language).
