How to use C to write a simple student dormitory management system?

The student dormitory management system is a software system that can conveniently manage student dormitory information. Using C to write a simple student dormitory management system can not only exercise your programming skills, but also improve your understanding and grasp of the student dormitory management process. This article will introduce how to use C to write a simple student dormitory management system.

First of all, we need to define the basic information of the student dormitory, including student name, student number, gender, contact information, etc. We can use a structure to store this information, as shown below:

struct Student {
    string name;
    int id;
    string gender;
    string contact;
};

Next, we need to define the basic information of the dormitory building, including the dormitory building number, number of floors, number of dormitory rooms on each floor, etc. We can use a class to represent the dormitory building, as shown below:

class Dormitory {
    private:
        int number;
        int floors;
        int roomsPerFloor;
        vector<vector<Student>> rooms;
    public:
        // 构造函数
        Dormitory(int n, int f, int r) {
            number = n;
            floors = f;
            roomsPerFloor = r;
            rooms.resize(floors, vector<Student>(roomsPerFloor));
        }
        // 获取宿舍楼号
        int getNumber() {
            return number;
        }
        // 获取楼层数
        int getFloors() {
            return floors;
        }
        // 获取每层宿舍房间数
        int getRoomsPerFloor() {
            return roomsPerFloor;
        }
        // 获取指定房间的学生信息
        Student getStudent(int floor, int room) {
            return rooms[floor][room];
        }
        // 更新指定房间的学生信息
        void updateStudent(int floor, int room, Student student) {
            rooms[floor][room] = student;
        }
};

Then, we can define a student dormitory management system class that contains the management functions of the student dormitory building. We can use a vector to store different dormitory buildings, as shown below:

class DormitoryManagementSystem {
    private:
        vector<Dormitory> dormitories;
    public:
        // 添加宿舍楼
        void addDormitory(int number, int floors, int roomsPerFloor) {
            dormitories.push_back(Dormitory(number, floors, roomsPerFloor));
        }
        // 获取宿舍楼个数
        int getDormitoryCount() {
            return dormitories.size();
        }
        // 获取指定宿舍楼对象
        Dormitory getDormitory(int index) {
            return dormitories[index];
        }
        // 获取指定宿舍楼的房间数
        int getRoomCount(int index) {
            return dormitories[index].getFloors() * dormitories[index].getRoomsPerFloor();
        }
        // 获取指定宿舍楼指定房间的学生信息
        Student getStudent(int index, int floor, int room) {
            return dormitories[index].getStudent(floor, room);
        }
        // 更新指定宿舍楼指定房间的学生信息
        void updateStudent(int index, int floor, int room, Student student) {
            dormitories[index].updateStudent(floor, room, student);
        }
};

Finally, we can write a main program to demonstrate the use of the student dormitory management system. The main program can provide menu functions, including adding dormitory buildings, viewing dormitory building information, adding student information, viewing student information, etc. The following is a simple main program example:

int main() {
    DormitoryManagementSystem system;
    int choice;
    do {
        cout << "1. 添加宿舍楼" << endl;
        cout << "2. 查看宿舍楼信息" << endl;
        cout << "3. 添加学生信息" << endl;
        cout << "4. 查看学生信息" << endl;
        cout << "0. 退出" << endl;
        cout << "请输入选项：";
        cin >> choice;
        switch (choice) {
            case 1:
                int number, floors, roomsPerFloor;
                cout << "请输入宿舍楼号：";
                cin >> number;
                cout << "请输入楼层数：";
                cin >> floors;
                cout << "请输入每层宿舍房间数：";
                cin >> roomsPerFloor;
                system.addDormitory(number, floors, roomsPerFloor);
                cout << "成功添加宿舍楼！" << endl;
                break;
            case 2:
                int index;
                cout << "请输入要查看的宿舍楼索引：";
                cin >> index;
                if (index >= 0 && index < system.getDormitoryCount()) {
                    Dormitory dorm = system.getDormitory(index);
                    cout << "宿舍楼号：" << dorm.getNumber() << endl;
                    cout << "楼层数：" << dorm.getFloors() << endl;
                    cout << "每层宿舍房间数：" << dorm.getRoomsPerFloor() << endl;
                    cout << "总房间数：" << system.getRoomCount(index) << endl;
                } else {
                    cout << "宿舍楼索引无效！" << endl;
                }
                break;
            case 3:
                int dormIndex, floor, room;
                string name, gender, contact;
                cout << "请输入要添加学生的宿舍楼索引：";
                cin >> dormIndex;
                if (dormIndex >= 0 && dormIndex < system.getDormitoryCount()) {
                    cout << "请输入学生所在楼层：";
                    cin >> floor;
                    cout << "请输入学生所在房间：";
                    cin >> room;
                    cout << "请输入学生姓名：";
                    cin >> name;
                    cout << "请输入学生性别：";
                    cin >> gender;
                    cout << "请输入学生联系方式：";
                    cin >> contact;
                    system.updateStudent(dormIndex, floor, room, {name, 0, gender, contact});
                    cout << "成功添加学生信息！" << endl;
                } else {
                    cout << "宿舍楼索引无效！" << endl;
                }
                break;
            case 4:
                int dormIndex, floor, room;
                cout << "请输入要查看学生的宿舍楼索引：";
                cin >> dormIndex;
                if (dormIndex >= 0 && dormIndex < system.getDormitoryCount()) {
                    cout << "请输入要查看学生的楼层：";
                    cin >> floor;
                    cout << "请输入要查看学生的房间：";
                    cin >> room;
                    Student student = system.getStudent(dormIndex, floor, room);
                    cout << "学生姓名：" << student.name << endl;
                    cout << "学生学号：" << student.id << endl;
                    cout << "学生性别：" << student.gender << endl;
                    cout << "学生联系方式：" << student.contact << endl;
                } else {
                    cout << "宿舍楼索引无效！" << endl;
                }
                break;
            case 0:
                break;
            default:
                cout << "无效选项，请重新输入！" << endl;
                break;
        }
        cout << endl;
    } while (choice != 0);
    return 0;
}

Through the above code, we can implement a simple student dormitory management system. Users can add dormitory buildings, view dormitory building information, add student information, and view student information according to the menu options, thereby conveniently managing student dormitory information.

To sum up, the key steps to write a simple student dormitory management system using C include defining the basic information of students and dormitory buildings, writing relevant classes and functions, and designing the main program to demonstrate the use of the system. By writing a student dormitory management system, we can improve our understanding and practical ability of C programming, and at the same time improve our mastery and application ability of student dormitory management processes.
