1、面向对象程序设计（C+）实验报告姓名：刘九州 学院：数学与计算机学院 班级：10级计算机大类三班 学号：100511314实验5 单继承一、实验目的1掌握派生的类别与方式； 2了解派生类中如何使用基类的成员、基类成员在派生类中的访问控制； 3. 掌握继承中构造函数和析构函数的调用过程。二、实验内容及步骤1. 给出一个Document类，从Document派生出Book类，增加PageCount变量。在主函数中进行测试，创建Book类对象并进行初始化，输出书名和页数。 2. 设计一个单基继承的类层次程序，利用Person类派生出Student类，增加属性xh（学号），Person类中至少有姓名、

2、年龄等数据成员，成员函数中构造函数对其初始化，析构函数释放相应存储单元，输出函数输出其数据成员的值，其它成员函数根据需要添加，在主函数中进行测试。3. 设计一个人员类person和一个日期类date，由人员类派生出学生类student和教师类professor，学生类和教师类的数据成员birthday为日期类。在主函数中进行测试。三、实验源程序和运行结果实验（一）源程序：#include#includeusing namespace std;class Documentpublic:Document();Document();Document(char*name);char *Name;voi
