实现一个简单的图书资源管理系统,管理维护已有图书资源,图书资源有不同的类型,有一般图书,杂志,电子资源等。不同资源有不同的属性和操作。
(1) 掌握继承与派生逻辑关系,能够判断类之间的关系是继承派生;
(2) 掌握继承派生中基类,子类的设计方法;
(3) 掌握使用基类,子类对象的方法
本题的设计思路如下,建立图书资源基类,并派生出一般图书、杂志、电子资源等子类。根据需要定义父类和子类的成员变量和成员函数,其中包括图书或资源的显示信息等函数。若扩展实现可以将图书馆设计为一个组合类,包含图书资源的对象数组,根据自己的掌握情况选择是否扩展。该题目主要涉及到的知识点有:继承、派生。
根据需求分析父类和子类中是否存在一些功能操作可以设计成为虚函数,或者可以进行操作符重载的设计与实现(可选),如图书或资源的显示信息等虚函数。将图书馆设计为一个组合类,图书馆类包含各种资源对象,优化设计,图书馆类包含基类(资源类)对象指针数组或动态数组(vector),将多种子类的对象统一到基类指针数组的数据结构下进行统一处理,利用基类指针调用虚函数,各个子类对象不同的功能仍然能够发挥出来。该题目主要涉及到的知识点有:组合、继承、派生、虚函数多态,操作符重载多态。
