实验报告4：群体类和群体数据

学校代码： 10128学 号： 0 面向对象程序设计实验报告（题 目：群体类和群体数据学生姓名：燕飞学 院：理学院系 别：数学系专 业：信息与计算科学班 级：信计12-2任课教师：侯睿 二 一 五 年 十 一 月1、 实验目的1、了解节点类的声明和实现，学习其使用方法2、了解链表类的声明和实现，学习其使用方法3、了解栈类的声明和实现，学习其使用方法4、了解队列类的声明和实现，学习其使用方法5、掌握对数组元素排序的方法6、掌握对数组元素查找的方法2、 实验内容1、编写程序Node.h实现例9-5的节点类，并编写测试程序lab9_1.cpp，实现链表的基本操作。2、编写程序link.h实现例9-6的链表类，在测试程序lab_2.cpp中声明两个整型链表A和B，分别插入5元素，然后把B中的元素加入A的尾部。3、编写程序queue.h，用链表实现队列（或栈），在测试程序lab9_3.cpp中声明一个整型队列（或栈）对象，插入5个整数，压入队列（或栈），再依次取出并显示出来。4、（选做）声明course（课程）类，有属性：课程名char name21、成绩short score；在实验七的student类中增加属性；所修课程course，为课程类对象的链表。在测试程序中测试这个类，学生类与课程类关系如图5、将直接插入排序、直接选择排序、冒泡排序、顺序查找函数封装到第九章的数组类中，作为成员函数，实现并测试这个类。3、 实验程序1、#ifndef NODE_CLASS#define NODE_CLASStemplate class Node private: Node *next;
