学生图书管理系统c++

好的，下面是一个简单的学生图书管理系统的C++代码示例，仅供参考：

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

const int MAXSIZE = 1000;  // 最大记录数

// 书籍信息结构体
struct Book {
    string id;          // 书籍编号
    string name;        // 书籍名称
    string author;      // 作者姓名
    string publisher;   // 出版社
    int total;          // 馆藏数量
    int remain;         // 剩余数量
};

// 学生信息结构体
struct Student {
    string id;          // 学生编号
    string name;        // 学生姓名
    string department;  // 学生所在院系
    int borrowed;       // 借阅数量
};

// 数据库类
class Library {
private:
    Book bookList[MAXSIZE];     // 书籍列表
    Student studentList[MAXSIZE];// 学生列表
    int bookCount;              // 书籍数量
    int studentCount;           // 学生数量
public:
    Library() { bookCount = studentCount = 0; } // 构造函数，初始化数量为0
    void addBook(Book book);                    // 添加书籍
    void addStudent(Student student);           // 添加学生
    void borrowBook(string bookId, string studentId);   // 借阅书籍
    void returnBook(string bookId, string studentId);   // 归还书籍
    void displayBooks();                        // 显示书籍列表

};

这是一个比较简单的代码示例，包括了添加书籍、添加学生、借阅书籍、归还书籍、显示书籍列表和显示学生列表等操作。如果需要扩展功能，可以在此基础上进行修改和完善。
