Copy constructor witl pure virtual + pointer

[aasaa]

Hi,

// my A.h

class A  // My interface
{
public:
	A(){ std::cout << " A-Ctor ";}
	A(const A& other){std::cout << " A Copy Ctor ";}
	
	virtual ~A(){ 	std::cout << " A dtor ";	 }
	virtual void Foo() const =0;
};

// my B.h
class B : public A
{
public:
	B(){ std::cout << " B-Ctor ";}
	virtual ~B(){ std::cout << " B-dtor ";	}
	B(const B& other) :A(other){
		std::cout << " B Copy Ctor ";
	}
	virtual void Foo() const{	}
};

//my main.cpp
// ... all includes
int main()
{
	B b1;
        A* = new A*(b1); // where copy made??

my Question in line A* = new A*(b1); where is the copy of object A* was made. what I know is that the copy constructors of A and B were not called !!

thanks.

I take it you mean A* a = new A(b1);.

Well, you can't instantiate your abstract class A. You have to instantiate a derived class that fills in pure virtual functions.

kbw, thanks. now whick copy constructor was called?

The code does not compile. A is not instantiable because it has a pure virtual function (Foo()).
If we pretend Foo() is not there, A::A(const A &) would be called.
