本文实例为大家分享了C++实现职工管理系统的具体代码，供大家参考，具体内容如下
1、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>
我们创建以下多个头文件和与其对应的 .cpp文件：
