C++数据封装和虚函数的探讨

C++Data Encapsulation & Virtual Function Research

本文以某大型图书馆媒介管理系统为背景,探讨了 C++数据封装和继承性在该系统设计方案中的应用特点,并分析了在某些情况下利用虚函数实现多态时效率不高的原因。

The thesis researches into the using characters of C++ data encapsulation and in heritance for the designed system,which is a library management information system.Moreover,it analyses how to utilize virtual function to improve efficiency for implementation polymorphism.
