area
定义一个基类MyGraph,要求有一个纯虚函数double Area()=0。从基类派生一个圆类Circle和矩形类Rectangle,再由Rectangle类派生出Square类,分别给出Area()实现。
重载“>>”,实现对图形信息的输入。在主函数中计算三种形状的面积,并显示输出。 (Define a base class MyGraph, requires a pure virtual function double Area () = 0. Derive a circle and a rectangle class Rectangle Circle class from the base class, and then by Square Rectangle class derived class, are given Area () implementation. Reload " > > " to achieve the input of graphical information. Calculate the shape of the three main functions in the area, and display output.)

1. 定义一个抽象学生类CStudent,它具有公有成员函数Average(),该函数用于计算学生的平均分,函数为虚函数;定义一个文科学生类CStudentLiberalArts,它是类CStudent的派生类,并以公有方式派生,它具有的成员有:
1) 保存英语、政治、数学、地理和历史、美术成绩的整形成员变量;
2) 设置上述变量的公有成员函数;
3) 输出上述变量的公有成员函数;
4) 公有的成员函数Average()用于计算学生的平均分;
定义一个理科学生类CStudentScience,它是类CStudent的派生类,并以公有方式派生,它具有的成员为:
1) 保存英语、物理、数学、化学和计算机、程序设计成绩的整形成员变量;
2) 设置上述变量的公有成员函数;
3) 输出上述变量的公有成员函数;
4) 公有的成员函数Average()用于计算学生的平均分;
编写主函数,并测试以下内容:
1) 定义一个CStudent的指针数组pStu,数组长度为4;
2) 动态创建2个文科学生的对象,地址存于pStu数组的0-1个元素内;
3) 动态创建2个理科学生的对象,地址存于pStu数组的2-3个元素内;
4) 利用while循环调用数组里每个元素的计算平均成绩操作;
释放动态分配的空间,确保必要的析构函数能被调用。
