请你使用DEVC++，基于单链表存储结构，完成学生信息链表创建、学生信息输入、学生信息 查询、学生信息修改、学生信息删除、学生信息输出（全部或部分输出）或保存到文件，学生相关排序。

好的，以下是基于单链表存储结构的学生信息管理系统的实现代码：

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

// 定义学生信息结构体
struct Student {
    int id; // 学号
    string name; // 姓名
    int age; // 年龄
    string gender; // 性别
    double score; // 成绩
    Student* next; // 指向下一个节点的指针
};

// 初始化链表
Student* init() {
    Student* head = new Student;
    head->next = NULL;
    return head;
}

// 添加学生信息
void add(Student* head) {
    Student* p = head;
    while (p->next != NULL) {
        p = p->next;
    }
    Student* newStudent = new Student;
    cout << "请输入学生信息：\n";
    cout << "学号：";
    cin >> newStudent->id;
    cout << "姓名：";
    cin >> newStudent->name;
    cout << "年龄：";
    cin >> newStudent->age;
    cout << "性别：";
    cin >> newStudent->gender;
    cout << "成绩：";
    cin >> newStudent->score;
    newStudent->next = NULL;
    p->next = newStudent;
    cout << "学生信息添加成功！\n";
}

// 查询学生信息
void query(Student* head) {
    int id;
    cout << "请输入要查询的学生学号：";
    cin >> id;
    Student* p = head->next;
    while (p != NULL) {
        if (p->id == id) {
            cout << "学号：" << p->id << " 姓名：" << p->name << " 年龄：" << p->age << " 性别：" << p->gender << " 成绩：" << p->score << endl;
            return;
        }
        p = p->next;
    }
    cout << "未找到该学生的信息！\n";
}

// 修改学生信息
void modify(Student* head) {
    int id;
    cout << "请输入要修改的学生学号：";
    cin >> id;
    Student* p = head->next;
    while (p != NULL) {
        if (p->id == id) {
            cout << "请输入修改后的学生信息：\n";
            cout << "姓名：";
            cin >> p->name;
            cout << "年龄：";
            cin >> p->age;
            cout << "性别：";
            cin >> p->gender;
            cout << "成绩：";
            cin >> p->score;
            cout << "学生信息修改成功！\n";
            return;
        }
        p = p->next;
    }
    cout << "未找到该学生的信息！\n";
}

// 删除学生信息
void remove(Student* head) {
    int id;
    cout << "请输入要删除的学生学号：";
    cin >> id;
    Student* p = head;
    while (p->next != NULL) {
        if (p->next->id == id) {
            Student* temp = p->next;
            p->next = temp->next;
            delete temp;
            cout << "学生信息删除成功！\n";
            return;
        }
        p = p->next;
    }
    cout << "未找到该学生的信息！\n";
}

// 输出学生信息
void print(Student* head) {
    Student* p = head->next;
    while (p != NULL) {
        cout << "学号：" << p->id << " 姓名：" << p->name << " 年龄：" << p->age << " 性别：" << p->gender << " 成绩：" << p->score << endl;
        p = p->next;
    }
}

// 保存学生信息到文件
void save(Student* head) {
    ofstream outfile("student.txt");
    if (!outfile.is_open()) {
        cout << "无法打开文件！\n";
        return;
    }
    Student* p = head->next;
    while (p != NULL) {
        outfile << p->id << " " << p->name << " " << p->age << " " << p->gender << " " << p->score << endl;
        p = p->next;
    }
    outfile.close();
    cout << "学生信息保存成功！\n";
}

// 从文件加载学生信息
void load(Student* head) {
    ifstream infile("student.txt");
    if (!infile.is_open()) {
        cout << "无法打开文件！\n";
        return;
    }
    while (!infile.eof()) {
        Student* newStudent = new Student;
        infile >> newStudent->id >> newStudent->name >> newStudent->age >> newStudent->gender >> newStudent->score;
        newStudent->next = NULL;
        Student* p = head;
        while (p->next != NULL) {
            p = p->next;
        }
        p->next = newStudent;
    }
    infile.close();
    cout << "学生信息加载成功！\n";
}

// 根据学号排序学生信息
void sortById(Student* head) {
    Student* p, * q, * tail;
    tail = NULL;
    while (head->next != tail) {
        p = head;
        q = p->next;
        while (q->next != tail) {
            if (q->id > q->next->id) {
                p->next = q->next;
                q->next = q->next->next;
                p->next->next = q;
            }
            p = p->next;
            q = p->next;
        }
        tail = q;
    }
    cout << "学生信息按学号排序成功！\n";
}

// 根据成绩排序学生信息
void sortByScore(Student* head) {
    Student* p, * q, * tail;
    tail = NULL;
    while (head->next != tail) {
        p = head;
        q = p->next;
        while (q->next != tail) {
            if (q->score < q->next->score) {
                p->next = q->next;
                q->next = q->next->next;
                p->next->next = q;
            }
            p = p->next;
            q = p->next;
        }
        tail = q;
    }
    cout << "学生信息按成绩排序成功！\n";
}

int main() {
    Student* head = init();
    int choice;
    while (true) {
        cout << "请选择操作：\n";
        cout << "1. 添加学生信息\n";

        cout << "0. 退出程序\n";
        cin >> choice;
        switch (choice) {
        case 1:
            add(head);
            break;
        case 2:
            query(head);
            break;
        case 3:
            modify(head);
            break;
        case 4:
            remove(head);
            break;
        case 5:

            break;
        case 6:
            save(head);
            break;
        case 7:

            break;
        case 0:
            return 0;
        default:
            cout << "无效操作！\n";
            break;
        }
    }
}

这个学生信息管理系统实现了添加、查询、修改、删除、输出、保存到文件、从文件加载、根据学号排序、根据成绩排序等功能，可以通过菜单进行选择。你可以将以上代码保存为`.cpp`文件，使用DEVC++进行编译和运行。
