Does derivated class inherit base class destructor (constructor)?


I have:
Code:
class A {
    public:
        ~A ();
};
Code:
class B: public A {
    public:
        void SomeFunc ();
};
Is it true that upon B destruction it automatically calls ~A () destructor (or somehow inherits it), or should I do:
Code:
B::~B () {
    A::~A ();
}
?

Thanks.

there is no need to explicity invoke the destructor.. you do need to make the base class destructor virtual. if you inherit from a class, that base class needs to have a virtual destructor.. ALWAYS, otherwise bad things will follow!
