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

题目：

设计一个虚基类Sta〒(员工)，包含编号、姓名和在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

SalesManager0

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、杳询数据、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删除标志的记录。)此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.分析二流程及编程思想：

首先定义•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

InputFromFilefistream&in)这一输入函数，此外每一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、瓷询、删除以及特定类别人员显示，特定类别人员数目显示的功能定

义addItemmodifyitem、find、removeitem以及display^findnumber函数。最后在主函数

定义Staff_Chart.Salesman_ChartxManagejChart和SalesManagejChart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：
