编写一个学生和教师数据输入和显示程序，学生数据有编号、姓名、班号和成绩教师数据有编号、姓名、职称和部门。要求将编号、姓名的输入和显示设计成

函数，班号、成绩、职称、部门可以直接在主函数中输入和显示。

以下是示例代码：

#include <iostream>
#include <string>

using namespace std;

struct Student {
    int id;
    string name;
    int classNum;
    double score;
};

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

void inputIdAndName(int& id, string& name) {
    cout << "请输入编号：";
    cin >> id;
    cout << "请输入姓名：";
    cin >> name;
}

void displayIdAndName(int id, string name) {
    cout << "编号：" << id << endl;
    cout << "姓名：" << name << endl;
}

int main() {
    Student stu;
    Teacher tea;

    // 输入学生数据
    cout << "请输入学生数据：" << endl;
    inputIdAndName(stu.id, stu.name);
    cout << "请输入班号：";
    cin >> stu.classNum;
    cout << "请输入成绩：";
    cin >> stu.score;

    // 显示学生数据
    cout << "学生数据：" << endl;
    displayIdAndName(stu.id, stu.name);
    cout << "班号：" << stu.classNum << endl;
    cout << "成绩：" << stu.score << endl;

    // 输入教师数据
    cout << "请输入教师数据：" << endl;
    inputIdAndName(tea.id, tea.name);
    cout << "请输入职称：";
    cin >> tea.title;
    cout << "请输入部门：";
    cin >> tea.department;

    // 显示教师数据
    cout << "教师数据：" << endl;
    displayIdAndName(tea.id, tea.name);
    cout << "职称：" << tea.title << endl;
    cout << "部门：" << tea.department << endl;

    return 0;
}
