雇员工资发放系统-2

2019年6月18日 2.63k次阅读 共8036个字   0条评论 0人点赞 SAGIRI

第四次上机：在雇员基本信息中增加雇员的生日（birthDate），并设计日期类（Date）来表示生日。在主函数中创建一个容器用来管理公司各种雇员对象，多态地计算并输出每个雇员的工资。如果雇员的生日在本月，就奖给该雇员100元。同时，在本次工资发放阶段，公司决定奖励带薪佣金雇员，把他们的基本工资提高10%。

设计提示：

  1. 使用抽象类。
  2. 如果一个类的全部成员和另一个类的部分成员相同，逻辑上是is-a的关系，考虑将两个类设计成继承关系。
  3. 实现“本次工资发放奖励带薪佣金雇员”时，可考虑采用动态类型转换。

例如：Base* pb;Derived *pd=dynamic_cast<Derived *>(pb); 若pd!=0则pd指向的是Derived 对象。

第一次编写日期类定义时编写了日期类的构造函数，但是这样的话就会出现输入雇员信息时要求先输入雇员生日信息的问题，虽然能够运行，但是对于正常使用的程序来讲一本书如人员信息都是先输入姓名，于是将日期类的成员都改为公有成员，并删除构造函数，改为在雇员类的构造函数直接输入生日信息

当设置目前时间时出现问题后，长时间无法解决，最终直接在构造函数中声明

生日判断函数最开始无法获取目前时间信息，发现目前时间的日期类声明位置错误，遂改正
