Destructing derived class by deleting base class

Question

I have a situation that looks like the following code:

#include 

class A
{
public:
    A() { std::cout << \"A created!\" << std::end         


        

Answer 1

Is this possible in its destructor or do I have to implement a virtual Destroy() method or something like that?

Make destructor of A virtual.

 virtual ~A() { std::cout << "A destroyed!" << std::endl; }

If your class have virtual methods, it should use virtual destructor. At least some compilers will complain if you aren't using virtual destructor in class with virtual methods.
