销售公司人员管理

1、销售公司人员管理C+大作业报告班级：031013 学号:姓名:销售公司员工管理一. 题目：设计一个虚基类Staff （员工），包含编号、 姓名和年龄保护数据成员以及相关的成员函数； 由Staff派生出销售员类Salesman,包含销售额 保护数据成员以及相关的成员函数；再由Staff派生出经理类 Manager;然后由Salesman和 Manager类派生出销售经理类SalesManager。设计一个利用文件处理方式实现对公司人 员（包括销售员、经理和销售经理）进行管理， 具有增加数据、更新数据、查询数据、删除数据 以及重组文件的功能。（删除数据在记录中做删 除标志，重组文件指在物理上删除有

2、删除标志的 记录。）另外要求分别统计这三类员工的人数以 及所有员工的总数。二. 分析，流程及编程思想：首先定义一个虚基类Staff类，然后通过虚 拟继承生成Salesman类和Manager类，最后由 Salesman和 Manager 派生出销售经理类 SalesManager 。 这四个类中定义 lnputFromFile（istream &in）这一输入函数，另外 每个类还定义输入信息和输出信息的成员函数 ， 之后定义 StaffChart、SalesmanChart、 ManagerChart 和 SalesManagerChart 四个类 来，为实现增加、更新、查询、删除以及

3、特定类 别人员显示，特定类别人员数目显示的功能定义 addItem、modifyitem、find、removeitem 以及 display、findnumber函数。最后在主函数定义 Staff_Chart、Salesman_Chart、Manager_Chart 和SalesManager_Chart四个对象，通过循环执 行并用switch函数选择功能，然后调用相关的 函数来实现各种功能。三. 实验代码：#in clude"iostream"#in clude"fstream" using n amespace std; class Staff p
