c++小学期的实验二

  实验一是做一个猜单词的游戏，bug太多，所以就不贴出来了。。。

  实验二的题目是：

1.完成图形类及其派生类的定义

(1) 设计一个计算图形面积的类库。它的顶层是一个抽象类，并且提供三个纯虚函数：显示数据成员、返回面积和返回体积。

class Shape

{public:

virtual void showData()=0;

        virtualdouble reArea()=0;

        virtualdouble reVolume()=0;

};

    第二层有Shape类派生TwoDimShape（二维图形）和ThreeShape（三维图形）类。他们增加了有关的数据成员，但没有成员函数的实现。

第三层派生具体的图形类。TwoDimShape类派生Circle（圆）、Elipse（椭圆）、Rectangle（矩形）和Triangle（三角形）等类。ThreeShape类派生Ball（球体）、Cylider（圆柱体）和RectangularParallelepiped（长方体）等类。

(2) 设计一个测试程序，全面测试你的设计，要求使用基类指针引用派生类对象的三个函数。

2.用异质链表组织上述各类图形对象。

(1) 实现单链表：将结点数据域定义为int，链表具有插入结点、删除结点、反转、遍历等功能，并测试其正确性。

(2) 将结点数据域定义修改为Shape *，用链表中的每个结点表示一个具体的图形对象，创建图形对象链表，并测试其正确性。

(3) 将所建单链表中的内容写到一个文本文件中，反转单链表并再次将其内容追加到同一文本文件中，查阅其正确性。

 代码有点累赘,用了许多if，有需要的话可以改成switch。另外可以实现保存链表到txt文本，从txt文本导入链表。虽然质量不高，bug也很多，大家就多多担待吧

  另外代码在cfree上编译通过的，推荐大家用cfree或mingw运行。
