这篇文章主要为大家详细介绍了C++实现公司人事管理系统，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文实例为大家分享了C++实现公司人事管理系统的具体代码，供大家参考，具体内容如下
一．问题描述
一个小公司包含四类人员：经理，技术人员，销售人员和销售经理，各类人员的工资计算方法如下：经理：固定月薪（8000）；技术人员：月薪按技术等级（1~8）（1600+等级*300）；销售人员：按提成（4%*销售额）；销售经理：底薪+提成（1500+0.2%*总销售额）；设计一个管理程序，实现对各类人员的信息输入，修改和显示。
二 .基本要求
（1）使用面向对象编程思想编写开发过程中需要用到的类，比如：设计Person类：编号，姓名，岗位，工资，成员函数可设一个计算月薪的纯虚函数；另外再设计四个针对四类人员的类均继承 Person；添加相应的派生类数据成员和函数，经理和销售经理可以没有新的数据成员，计算月薪即可； 技术人员添加技术等级数据成员，销售人员添加数据成员：销售额。还需设计一个Manage 类来完成各种操作。人员数组 vector，数据类型为基类指针。
（2）需要使用菜单功能显示添加人员（输入），修改信息，浏览信息，按姓名查找，月薪排序。
（3）为了设计简洁，假定经理和销售经理都只能有一个；用文本编辑器编辑一个文本文件（总数 20 人以上）包含各类人员的信息；并且在程序中能修改保存。
