用C++写高校员工信息管理系统，人员包括教师，实验员，行政人员，教师兼行政人员，功能包括添加，查询，显示，编辑，删除，统计，保存，读取

好的，这个高校员工信息管理系统可以分为以下几个模块：

1. 员工类（Teacher、LabStaff、Admin、TeacherAdmin）：这些类都是继承于基类Employee，每个员工类都包含一些特定属性（如教师类包含授课科目等），以及一些公共属性（如姓名、性别、年龄等）和方法（如获取员工信息、修改员工信息等）。

2. 员工管理类（EmployeeManager）：这个类用于实现对员工信息的添加、查询、显示、编辑、删除、统计、保存、读取等功能。其中，添加和编辑功能需要根据用户选择的员工类型创建相应的对象，并向对象中添加员工信息。查询和删除功能需要根据用户输入的员工ID进行查找。统计功能用于计算各类员工的数量和平均年龄等信息。保存和读取功能用于将员工信息存储到文件中或从文件中读取员工信息。

3. 界面类（Interface）：这个类用于实现与用户交互的界面，包括菜单、输入输出等。

下面是一个简单的示例代码：

#include <iostream>
#include <vector>
#include <fstream>
