一、验证性实验1. 在多层继承中，派生类中出现与基类同名成员时，通过对象名.成员名的方式，访问的成员什么？ 对象名.成员名：派生类对象2. 通过基类指针访问派生类对象时，基类中成员函数有无关键字virtual，访问的成员分别是什么？ 基类指针：有关键字时访问派生类，无关键

part 1 两个问题： 1、派生类中出现与基类同名成员，通过对象名.成员名的方式，即代码中base2.display()，访问的成员是派生类中的成员 2、通过基类指针访问派生类对象时，在ex1_1.cpp中没有virtual，得到的结果全是基类成员函数的调用，在ex1_2.cpp中基类成员函数有virtual，结果基类派生类都依次
