I'm wondering if it's possible to declare a pure virtual member function?
Ie is:
class A{
public:
virtual static void f() const = 0;
};
legal? I'm getting compile errors for code that used to work before I added
the changes in, and I'm not sure if that's causing it.

Hi,
I am not sure if the virtual keyword for the derived classes are
required given
that the base class already declares it virtual.

public:
virtual ~A();

Hi Folks!
Everytime I work with virtual and pure virtual methods I ask myself if
there is a difference between class B and class C (see below). Is it
redundant to repeat the virtual keyword in a derived class? Or is there
any difference I need to consider? I have seen both ways when I read
source code from external sources. So far I didn't find any answers in
my books or on the net.
