C++职工管理系统
鎃龘䰢 人气:01、管理系统需求
职工管理系统可以用来管理公司内所有员工的信息
利用C++来实现一个基于多态的职工管理系统
公司中职工分为三类：普通员工、经理、老板，显示信息时，需要显示职工编号、职工姓名、职工岗位、以及职责
普通员工职责：完成经理交给的任务
经理职责：完成老板交给的任务，并下发任务给员工
老板职责：管理公司所有事务
管理系统中需要实现的功能如下：
- 退出管理程序：退出当前管理系统
- 增加职工信息：实现批量添加职工功能，将信息录入到文件中，职工信息为：职工编号、姓名、部门编号
- 显示职工信息：显示公司内部所有职工的信息
- 删除离职职工：按照编号删除指定的职工
- 修改职工信息：按照编号修改职工个人信息
- 查找职工信息：按照职工的编号或者职工的姓名进行查找相关的人员信息
- 按照编号排序：按照职工编号，进行排序，排序规则由用户指定
- 清空所有文档：清空文件中记录的所有职工信息 （清空前需要再次确认，防止误删）
我们创建以下多个头文件和与其对应的 .cpp文件：
