函数指针获取成员函数地址（包括虚函数）

class Base
{
public:
	void () { printf("Enter Base::func()n"); }
	virtual void virtual_func() { printf("Enter Base::virtual_func()n"); }
};
class Derived : public Base
{
public:
	void () { printf("Enter Derived::func()n"); }
	virtual void virtual_func() { printf("Enter Derived::virtual_func()n"); }
};
typedef void (Base::*p_base_func)();
int main(int argc, char* argv[]) 
{ 
	Derived d;
	Base b;
	Base *pb = &d;
	p_base_func pbf = &Base::func;
	printf("-- Call via pointer to normal function of basen");
	(pb->*pbf)();
	(d.*pbf)();
	cout << endl;
	
	cout << endl << endl;
	pbf = &Base::virtual_func;
	printf("-- Call via pointer to virtual function of basen");
	(pb->*pbf)();
	(d.*pbf)();
	
	system("pause");
	return 0; 
}
