师兄用VC写的由湿地DEM生成的三维模型，赋有纹理，可以动态漫游，地理分析。希望对搞GIS开发的朋友有所帮助。包含DEM和纹理数据，所以有点大，请耐心下载。(senior VC written by DEM wetlands generated 3D model, endowed with texture, dynamic roaming, geographic analysis. Hope to engage in the development of the GIS friends help. DEM contains data and texture, a bit, please download patience.)

RDA5815 datasheet V2.0

NSpecify is a Behavior-Driven Development Framework developed in C#.NET.

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.)
