题目内容 (请给出正确答案)

如有基类Base和派生类Derived,实例化对象Base b; Derived d;叙述正确的是:

A.Derived* pDev = new Base();

B.Derived类中不能定义与Base类同名的成员,以免引用时引起歧义;

C.Base* pb =&d ; Derived* pd = &b; 为正确的赋值操作;

D.Base& rb = d; Base bb = d; 为正确的赋值操作;


参考答案和解析
Derived(int x): Base(x) { }

考题 如果不能使用多态机制,那么通过基类的指针虽然可以指向派生类对象,但是只能访问从基数继承的成员,下列程序没有使用多态机制,其输出结果是( ) 。#includeusing namespace std;class Base{public:Void print(){cout ‘B’;}};class Derived: public Base{publicvoid print(){cout ‘D’;}}int main(){Derived*pd=new Dreived);Base*pb=pd;pb-print();pd-print();delete pd;return 0;}

考题 在声明派生类时,如果不显式地给出继承方式,缺省的类继承方式是私有继承 private。已知有如下类定义:class Base{protected:void fun(){}};Class Derived: Base{};则Base 类中的成员函数fun(),在Derived 类中的访问权限是 [12] (注意:要求填写private、protected 或public 中的一项)。
