struct Derived 3 : public Derived 2{
virtual int vf2 (int);

WHY DIFFERENT? WHY SHOULD BE CAREFUL HERE? I AM LOST
================
they are different because they have different name.
be careful because this vf1() has different signature than vf1() derived
from its superclass: int vf1(int) <=> int vf1(void), so it's a new function.
i personally think they have nothing to do with virtual functions, but trick
things.
================
virtual int vf1 (int); // B

does not overload vf1() |
