一个类有虚拟数据成员吗？ [英] can a class have virtual data members?

问题描述

class Base{  
    public:  
        void counter();   
    ....   
}

class Dervied: public Base{  
    public:  
        ....  
}

void main()  
{  
     Base *ptr=new Derived;  
     ptr->counter();  
}

要标识基类指针指向派生类，成员函数，我们使用虚拟。

To identify that the base class pointer is pointing to derived class and using a derived member function, we make use of "virtual".

同样，我们可以使派生数据成员虚拟吗？ （数据成员是公开的）

Similarly, can we make derived data members "virtual"? (the data member is public)

推荐答案

virtual > Function specifier ...

virtual is a Function specifier...

从标准文档中，

7.1.2 Function specifiers
Function-specifiers can be used only in function declarations.
function-specifier:
inline
virtual
explicit

<

So there is nothing called Virtual data member.

希望它有助于...
