[转载]虚函数在构造函数中，已经失去了虚函数的动态绑定特性

class A
{
public:
        A()
        {
                Print();
        }
        virtual void Print()
        {
                printf("A is constructed.\n");
        }
};
 
class B: public A
{
public:
        B()
        {
                Print();
        }
 
        virtual void Print()
        {
                printf("B is constructed.\n");
        }
};
 
int _tmain(int argc, _TCHAR* argv[])
{
        A* pA = new B();
        delete pA;
 
        return 0;
}
