C++实现高校人员信息管理系统

高校人员信息管理系统设计，供大家参考，具体内容如下

一、问题描述及功能要求

1、问题描述

某高校有四类员工：教师、实验员、行政人员，教师兼行政人员；共有的信息包括：编号、姓名、性别、年龄等。其中，教师还包含的信息有：所在系部、专业、职称；实验员还包含的信息由：所在实验室、职务；行政人员还包含的信息有：政治面貌、职称等。

2、功能要求

（1）添加功能：程序能够任意添加上述四类人员的记录，可提供选择界面供用户选择所要添加的人员类别，要求员工的编号要唯一，如果添加了重复编号的记录时，则提示数据添加重复并取消添加。
（2）查询功能：可根据编号、姓名等信息对已添加的记录进行查询，如果未找到，给出相应的提示信息，如果找到，则显示相应的记录信息。
（3）显示功能：可显示当前系统中所有记录，每条记录占据一行。
（4）编辑功能：可根据查询结果对相应的记录进行修改，修改时注意编号的唯一性。
（5）删除功能：主要实现对已添加的人员记录进行删除。如果当前系统中没有相应的人员记录，则提示“记录为空！”并返回操作；否则，输入要删除的人员的编号或姓名，根据所输入的信息删除该人员记录，如果没有找到该人员信息，则提示相应的记录不存。
（6）统计功能：能根据多种参数进行人员的统计。能统计四类人员数量以及总数，统计男、女员工的数量。
（7）保存功能：可将当前系统中各类人员记录存入文件中，存入方式任意。
（8）读取功能：可将保存在文件中的人员信息读入到当前系统中，供用户进行使用。

二、代码实现 带有注释

废话不说，直接代码，欢迎指正。
