宿舍管理系统用c++写出来

好的，以下是一个简单的宿舍管理系统的C++代码，包含了学生、宿舍房间和宿舍楼类的设计和实现，以及一些基本的操作函数。这个代码仅供参考，您可以根据实际需求进行修改和优化。

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

// 宿舍房间类

// 宿舍管理系统类

private:

    // 根据学号查找学生
    Student* findStudentById(string id) {
        for (auto student : m_students) {
            if (student->getId() == id) {
                return student;
            }
        }
        return nullptr;
    }
};

int main() {
    DormitorySystem system;

    // 创建学生
    Student* s1 = new Student("Alice", "1001", "female", 18);
    Student* s2 = new Student("Bob", "1002", "male", 19);
    Student* s3 = new Student("Charlie", "1003", "male", 20);

    // 添加学生
    system.addStudent(s1);
    system.addStudent(s2);
    system.addStudent(s3);

    // 创建宿舍楼
    Building* building1 = new Building("Building 1", 5, 10, 2);
    Building* building2 = new Building("Building 2", 3, 8, 3);

    // 入住和退房
    system.checkIn("1001", 101, building1);
    system.checkIn("1002", 201, building1);
    system.checkIn("1003", 301, building1);
    system.checkOut("1002", 201, building1);
    system.checkIn("1002", 201, building1);

    system.checkIn("1001", 101, building2);
    system.checkIn("1002", 201, building2);
    system.checkIn("1003", 301, building2);
    system.checkOut("1001", 101, building2);
    system.checkOut("1002", 201, building2);

    // 查询学生信息
    system.findStudent("1001");
    system.findStudent("1002");
    system.findStudent("1003");

    // 释放内存
    delete s1;
    delete s2;
    delete s3;

    delete building1;
    delete building2;

    return 0;
}

这个代码实现了添加学生、查询学生信息、入住和退房等基本功能，同时使用了学生、宿舍房间和宿舍楼三个类来存储和管理信息。在实际应用中，您可能需要根据实际需求进行修改和优化。
