图书馆借阅管理系统C++代码

图书馆借阅管理系统的C++代码通常包含几个关键组件，如图书实体、会员实体、借阅记录等。以下是一个简单的例子，展示了如何用C++实现基本的功能：

#include <iostream>
#include <string>
#include <vector>

// 图书类
class Book {
public:
    std::string title;
    int id;

    // 构造函数
    Book(int id, const std::string& title) : id(id), title(title) {}
};

// 会员类
class Member {
private:
    std::string name;
    int membership_id;

public:
    Member(const std::string& name, int membership_id)
        : name(name), membership_id(membership_id) {}

    // 借书和还书方法
    void borrow(Book& book) {
        if (book.isAvailable()) {
            book.setAvailable(false);
            // 添加借书记录
            std::cout << "Member " << name << " borrowed book with ID: " << book.id << "\n";
        } else {
            std::cout << "Book is not available.\n";
        }
    }

    void returnBook(Book& book) {
        if (!book.isAvailable()) {
            book.setAvailable(true);
            std::cout << "Member " << name << " returned book with ID: " << book.id << "\n";
        } else {
            std::cout << "Book was already returned.\n";
        }
    }
};

// 图书馆类
class Library {
private:
    std::vector<Book> books;
    std::vector<Member> members;

public:
    void addBook(Book book) { books.push_back(book); }
    void addMember(Member member) { members.push_back(member); }

    // 其他方法，比如搜索书籍，更新库存等
};

int main() {
    // 创建并添加书籍和会员
    Book book1(1, "The Catcher in the Rye");
    Book book2(2, "To Kill a Mockingbird");

    Member member1("Alice", 1001);
    Member member2("Bob", 1002);

    Library lib;
    lib.addBook(book1);
    lib.addBook(book2);
    lib.addMember(member1);
    lib.addMember(member2);

    // 成员借阅书籍
    member1.borrow(book1);
    member2.borrow(book2);

    return 0;
}

这个示例包含了基本的图书（Book）类、会员（Member）类以及图书馆（Library）类。成员可以在图书馆里借阅和归还书籍。实际应用可能还会包括数据库操作、错误处理和其他复杂功能。
