设计一个图书管理系统 C++

好的，下面是一个简单的图书管理系统的 C++ 代码实现：

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

//定义一个图书类
class Book {
private:
    string name; //书名
    string author; //作者
    string publisher; //出版社
    double price; //价格
    int stock; //库存
public:
    Book() {}
    Book(string name, string author, string publisher, double price, int stock) {
        this->name = name;
        this->author = author;
        this->publisher = publisher;
        this->price = price;
        this->stock = stock;
    }

    //获取图书信息
    string getName() {
        return name;
    }
    string getAuthor() {
        return author;
    }
    string getPublisher() {
        return publisher;
    }
    double getPrice() {
        return price;
    }
    int getStock() {
        return stock;
    }

    //修改图书信息
    void setName(string name) {
        this->name = name;
    }
    void setAuthor(string author) {
        this->author = author;
    }
    void setPublisher(string publisher) {
        this->publisher = publisher;
    }
    void setPrice(double price) {
        this->price = price;
    }
    void setStock(int stock) {
        this->stock = stock;
    }
};

//定义一个图书管理系统类
class BookManager {
private:
    Book books[100]; //图书数组
    int count; //图书数量
public:
    BookManager() {
        count = 0;
    }

    //添加图书
    void addBook(Book book) {
        books[count++] = book;
    }

    //删除图书
    void deleteBook(string name) {
        for (int i = 0; i < count; i++) {
            if (books[i].getName() == name) {
                for (int j = i; j < count - 1; j++) {
                    books[j] = books[j + 1];
                }
                count--;
                break;
            }
        }
    }

    //修改图书信息
    void modifyBook(string name, Book book) {
        for (int i = 0; i < count; i++) {
            if (books[i].getName() == name) {
                books[i] = book;
                break;
            }
        }
    }

    //查找图书
    Book* findBook(string name) {
        for (int i = 0; i < count; i++) {
            if (books[i].getName() == name) {
                return &books[i];
            }
        }
        return NULL;
    }

    //展示图书信息
    void showBooks() {
        for (int i = 0; i < count; i++) {
            cout << "书名：" << books[i].getName() << " 作者：" << books[i].getAuthor() << " 出版社：" << books[i].getPublisher() << " 价格：" << books[i].getPrice() << " 库存：" << books[i].getStock() << endl;
        }
    }
};

int main() {
    BookManager bm;
    bm.addBook(Book("C++程序设计", "谭浩强", "清华大学出版社", 68.0, 10));
    bm.addBook(Book("Java编程思想", "Bruce Eckel", "机械工业出版社", 98.0, 5));
    bm.showBooks();
    bm.modifyBook("Java编程思想", Book("Java编程思想", "Bruce Eckel", "机械工业出版社", 108.0, 5));
    bm.showBooks();
    bm.deleteBook("C++程序设计");
    bm.showBooks();
    return 0;
}

这个系统实现了基本的添加、删除、修改、查找和展示图书信息等功能，你可以根据实际需求进行扩展。
