用c++写一个高校师生信息管理系统，功能包括添加，查询，显示，编辑，删除，统计，保存，读取

好的，以下是一个简单的高校师生信息管理系统的代码示例：

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

using namespace std;

struct Student {
    string name;
    int age;
    string major;
    int id;
};

struct Teacher {
    string name;
    int age;
    string department;
    int id;
};

// 添加学生信息
void add_student(vector<Student>& students) {
    Student s;
    cout << "请输入学生姓名：";
    cin >> s.name;
    cout << "请输入学生年龄：";
    cin >> s.age;
    cout << "请输入学生专业：";
    cin >> s.major;
    cout << "请输入学生学号：";
    cin >> s.id;
    students.push_back(s);
    cout << "添加成功！" << endl;
}

// 添加教师信息
void add_teacher(vector<Teacher>& teachers) {
    Teacher t;
    cout << "请输入教师姓名：";
    cin >> t.name;
    cout << "请输入教师年龄：";
    cin >> t.age;
    cout << "请输入教师所在院系：";
    cin >> t.department;
    cout << "请输入教师工号：";
    cin >> t.id;
    teachers.push_back(t);
    cout << "添加成功！" << endl;
}

// 查询学生信息
void search_student(const vector<Student>& students) {
    int id;

            return;
        }

void count(const vector<Student>& students, const vector<Teacher>& teachers) {
    cout << "学生人数：" << students.size() << endl;

这个代码示例实现了一个简单的高校师生信息管理系统，包括添加、查询、显示、编辑、删除、统计、保存和读取等功能。用户可以通过命令行菜单进行操作，所有信息都保存在内存中，并可以保存到文件中。注意，这个示例代码还有很多可以改进的地方，如增加输入检查、优化文件读写等。
