CRC源代码，C语言编写，希望各位同学下载斧正交流(CRC ABBBABFABBFABFBDABFABDBFABFA)

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.)

说明：  这是用Visual Basic写的读取SGI文件的样例程序(This is written in Visual Basic reader SGI document of the sample program)
