c++ - 基类私有(private)成员属于派生类的哪一部分？

Question

class base {
    public:
        int getC() {return c;}
        int a;
    protected:
        int b;
    private:
        int c;
}

class derived: public base {
    public:
        int getD() {return d;}
    private:
        int d;
}

现在，派生类有公共(public)成员:

int getC() {return c;}
int getD() {return d;}
int a;

protected 成员: int b; 私有(private)成员: int d; 我无法确认 int c;是派生类的私有(private)成员。很明显 class derived 的任何新成员函数无法访问 c .所以，如果 c是 class derived 的私有(private)成员, class derived 的成员函数应该有权访问 c .所以c是派生类的什么样的成员？

Answer 1

A derived class doesn't inherit access to private data members. However, it does inherit a full parent object, which contains any private members which that class declares.
