C/C++ code

class A{public:virtual void fun(){    printf("1");}};class B : public A{    public:    virtual void fun()    {        printf("2");    }};class C : public A{    public:    virtual void fun()    {        printf("3");    }};class D : public B , public C{};int _tmain(int argc, _TCHAR* argv[]){    C c;    c.fun();    return 0;}
