用C＋＋设计多态的显示方式

用面向对象设计（ＯＯＰ）的方法设计一个符合ＣＥＳＡ标准的用于显示的对象类。该类封装了多态的操作方式，用以对图像进行显示和保存。它能根据当时任务要求及环境自动地选择最佳存贮空间（常规内存、扩展内存或磁盘），是一种智能多态显示方法，实现了方便程序设计、缩短开发周期、提高系统重用性、减少后继阶段错误、提高可维护性等Ｃ＋＋的优点。由于本实现的智能型多态显示方法还能根据函数中参数值的大小不同来选择多态的操

Applying OOP to Design a Polymorphism Screen-show Function

A class for VESA showing function was designed by using Object OrientedProgramming methods. This class is provided with some Artificial Intelligence. It willautochoose the best storing-room (normal memory, expand memory and disk). Thismethod can carry into convenient effect, short developing period, advance re-using ofsoftware, reduce bugs, enhance maintain etc. advantages. Specially, the ArtificialIntelligence Polymorphism is different from usual C++ according different parameter,then widen use of C++ is applied.
