用c++写一个学生学籍管理系统

好的，我可以为您提供一个简单的学生学籍管理系统的C++代码框架，您可以根据自己的需求进行修改和完善。

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

// 学生类
class Student {
public:
    string name; // 姓名
    int age; // 年龄
    string gender; // 性别
    string id; // 学号

    // 构造函数
    Student(string n, int a, string g, string i) {
        name = n;
        age = a;
        gender = g;
        id = i;
    }

    // 显示学生信息
    void display() {
        cout << "姓名：" << name << endl;
        cout << "年龄：" << age << endl;
        cout << "性别：" << gender << endl;
        cout << "学号：" << id << endl;
    }
};

// 学生管理系统类
class StudentManager {
private:
    Student* students; // 学生数组
    int count; // 学生数量

public:
    // 构造函数
    StudentManager() {
        students = new Student[100];
        count = 0;
    }

    // 添加学生
    void addStudent() {
        string name, gender, id;
        int age;

        cout << "请输入学生姓名：";
        cin >> name;
        cout << "请输入学生年龄：";
        cin >> age;
        cout << "请输入学生性别：";
        cin >> gender;
        cout << "请输入学生学号：";
        cin >> id;

        Student student(name, age, gender, id);
        students[count] = student;
        count++;

        cout << "添加成功！" << endl;
    }

    // 显示所有学生信息
    void displayAll() {
        for (int i = 0; i < count; i++) {
            students[i].display();
            cout << endl;
        }
    }

    // 查找学生
    Student* findStudent(string id) {
        for (int i = 0; i < count; i++) {
            if (students[i].id == id) {
                return &students[i];
            }
        }

        return NULL;
    }

    // 删除学生
    void deleteStudent(string id) {
        for (int i = 0; i < count; i++) {
            if (students[i].id == id) {
                for (int j = i; j < count - 1; j++) {
                    students[j] = students[j + 1];
                }

                count--;
                cout << "删除成功！" << endl;
                return;
            }
        }

        cout << "未找到该学生！" << endl;
    }

    // 修改学生信息
    void modifyStudent(string id) {
        Student* student = findStudent(id);

        if (student != NULL) {
            string name, gender;
            int age;

            cout << "请输入学生姓名：";
            cin >> name;
            cout << "请输入学生年龄：";
            cin >> age;
            cout << "请输入学生性别：";
            cin >> gender;

            student->name = name;
            student->age = age;
            student->gender = gender;

            cout << "修改成功！" << endl;
        }
        else {
            cout << "未找到该学生！" << endl;
        }
    }
};

// 主函数
int main() {
    StudentManager manager;
    int choice;
    string id;

    do {
        cout << "请选择操作：" << endl;
        cout << "1.添加学生" << endl;
        cout << "2.显示所有学生" << endl;
        cout << "3.查找学生" << endl;
        cout << "4.删除学生" << endl;
        cout << "5.修改学生信息" << endl;
        cout << "0.退出" << endl;
        cout << "请选择：";
        cin >> choice;

        switch (choice) {
        case 1:
            manager.addStudent();
            break;
        case 2:
            manager.displayAll();
            break;
        case 3:
            cout << "请输入学生学号：";
            cin >> id;
            manager.findStudent(id)->display();
            break;
        case 4:
            cout << "请输入学生学号：";
            cin >> id;
            manager.deleteStudent(id);
            break;
        case 5:
            cout << "请输入学生学号：";
            cin >> id;
            manager.modifyStudent(id);
            break;
        case 0:
            break;
        default:
            cout << "输入错误，请重新输入！" << endl;
            break;
        }

        cout << endl;
    } while (choice != 0);

    return 0;
}

这个代码框架包含了基本的学生信息的添加、显示、查找、删除和修改等功能。您可以根据自己的需求进行修改和完善。
