销售公司人员管理

1、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删除标志的记录。

2、)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 InputFrom &n) 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、 删除以及特定类别人员显示, 特定类别人员数目显示的功能定义addItem、

3、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：#includeiostream #includefstream using namespace std;class Staffprotected:char num10;char name10;int age;public:Staff
