多继承基类中有同名虚函数

#include<iostream>
using namespace std;
class Base1 
{ 
public: 
virtual void Test()
{ 
cout<<"Base1 Test()"<<endl;
}
}; 
class Base2 
{ 
public: 
virtual void Test()
{ 
cout<<"Base2 Test()"<<endl;
}
}; 
class Derived :public Base1, public Base2 
{ 
public: 
    void Test() // 直接重写虚函数Test() 
{ 
cout<<"Derived Test()"<<endl;
}   
}; 
int main() 
{ 
    Derived D; 
D.Base1::Test();
D.Test();
    Base1 *pB1 = &D; 
    Base2 *pB2 = &D; 
Base1 b1;
b1.Test();
    pB1->Test(); //用基类指针pB1调用类Derived 的TestA()函数 
    pB2->Test(); //用基类指针pB2调用类Derived的TestB()函数 
return 0;
