Question

#include class A { public: int n; }; class B:virtual public

Answer 1

不晓得楼主问题是什么,但是根据我的猜测应该是帮你调试程序吧.

#include

using namespace std;

class A

{

public:

int n;

};

class B:virtual public A {};

class C:virtual public A {};

class D:public B ,public C

{

int getn(){return B::n;};

};

int main()

{

D d;

d.B::n=10;

d.C::n=20;

cout
