数据结构课程设计c++宿舍管理系统

以下是一个简单的C++宿舍管理系统的示例，使用了链表来存储学生信息和宿舍信息：

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

// 学生信息结构体
struct Student {
    string name; // 姓名
    int age; // 年龄
    string gender; // 性别
    string dorm; // 宿舍号
    Student* next; // 指向下一个学生的指针
};

// 宿舍信息结构体
struct Dorm {
    string dorm; // 宿舍号
    int capacity; // 容纳人数
    int count; // 当前人数
    Dorm* next; // 指向下一个宿舍的指针
};

// 添加学生信息
void addStudent(Student*& head) {
    Student* p = new Student;
    cout << "请输入学生姓名：";
    cin >> p->name;
    cout << "请输入学生年龄：";
    cin >> p->age;
    cout << "请输入学生性别：";
    cin >> p->gender;
    cout << "请输入学生宿舍号：";
    cin >> p->dorm;
    p->next = head;
    head = p;
}

// 添加宿舍信息
void addDorm(Dorm*& head) {
    Dorm* p = new Dorm;
    cout << "请输入宿舍号：";
    cin >> p->dorm;
    cout << "请输入宿舍容纳人数：";
    cin >> p->capacity;
    p->count = 0;
    p->next = head;
    head = p;
}

// 显示学生信息
void showStudent(Student* head) {
    cout << "姓名\t年龄\t性别\t宿舍号" << endl;
    while (head != NULL) {
        cout << head->name << "\t" << head->age << "\t" << head->gender << "\t" << head->dorm << endl;
        head = head->next;
    }
}

// 显示宿舍信息
void showDorm(Dorm* head) {
    cout << "宿舍号\t容纳人数\t当前人数" << endl;
    while (head != NULL) {
        cout << head->dorm << "\t" << head->capacity << "\t" << head->count << endl;
        head = head->next;
    }
}

// 保存学生信息到文件
void saveStudent(Student* head) {
    ofstream outfile("student.txt");
    while (head != NULL) {
        outfile << head->name << " " << head->age << " " << head->gender << " " << head->dorm << endl;
        head = head->next;
    }
    outfile.close();
}

// 保存宿舍信息到文件
void saveDorm(Dorm* head) {
    ofstream outfile("dorm.txt");
    while (head != NULL) {
        outfile << head->dorm << " " << head->capacity << " " << head->count << endl;
        head = head->next;
    }
    outfile.close();
}

// 从文件中读取学生信息
void loadStudent(Student*& head) {
    ifstream infile("student.txt");
    while (!infile.eof()) {
        Student* p = new Student;
        infile >> p->name >> p->age >> p->gender >> p->dorm;
        p->next = head;
        head = p;
    }
    infile.close();
}

// 从文件中读取宿舍信息
void loadDorm(Dorm*& head) {
    ifstream infile("dorm.txt");
    while (!infile.eof()) {
        Dorm* p = new Dorm;
        infile >> p->dorm >> p->capacity >> p->count;
        p->next = head;
        head = p;
    }
    infile.close();
}

int main() {
    Student* studentHead = NULL;
    Dorm* dormHead = NULL;
    loadStudent(studentHead);
    loadDorm(dormHead);
    int choice;
    do {
        cout << "请选择操作：" << endl;
        cout << "1. 添加学生信息" << endl;
        cout << "2. 添加宿舍信息" << endl;
        cout << "3. 显示学生信息" << endl;
        cout << "4. 显示宿舍信息" << endl;
        cout << "5. 保存信息到文件" << endl;
        cout << "6. 退出" << endl;
        cin >> choice;
        switch (choice) {
            case 1:
                addStudent(studentHead);
                break;
            case 2:
                addDorm(dormHead);

                break;
            case 5:
                saveStudent(studentHead);
                saveDorm(dormHead);                break;
            case 6:
                break;
            default:
                cout << "无效的选择，请重新输入！" << endl;
                break;
        }
    } while (choice != 6);
    return 0;
