c++实现控制台图书管理系统

好的，下面是一个简单的控制台图书管理系统的C++实现：

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

const int MAX_BOOKS = 100;

class Book {
private:
    string title;
    string author;
    int year;
public:
    Book(string title = "", string author = "", int year = 0) {
        this->title = title;
        this->author = author;
        this->year = year;
    }
    string getTitle() {
        return title;
    }
    string getAuthor() {
        return author;
    }
    int getYear() {
        return year;
    }
};

class Library {
private:
    Book books[MAX_BOOKS];
    int numBooks;
public:
    Library() {
        numBooks = 0;
    }
    void addBook(string title, string author, int year) {
        if (numBooks < MAX_BOOKS) {
            books[numBooks++] = Book(title, author, year);
            cout << "Book added successfully!" << endl;
        }
        else {
            cout << "Library is full!" << endl;
        }
    }
    void listBooks() {
        if (numBooks == 0) {
            cout << "Library is empty!" << endl;
        }
        else {
            cout << "Library contents:" << endl;
            for (int i = 0; i < numBooks; i++) {
                cout << books[i].getTitle() << " by " << books[i].getAuthor() << " (" << books[i].getYear() << ")" << endl;
            }
        }
    }
};

int main() {
    Library library;
    int choice;
    string title, author;
    int year;
    do {
        cout << "Select an option:" << endl;
        cout << "1. Add book" << endl;
        cout << "2. List books" << endl;
        cout << "3. Quit" << endl;
        cin >> choice;
        switch (choice) {
            case 1:
                cout << "Enter title, author, and year:" << endl;
                cin >> title >> author >> year;
                library.addBook(title, author, year);
                break;
            case 2:
                library.listBooks();
                break;
            case 3:
                break;
            default:
                cout << "Invalid option!" << endl;
                break;
        }
    } while (choice != 3);
    return 0;
}

这个系统包含两个类：`Book`和`Library`。`Book`类表示一本书，包含标题、作者和年份等信息；`Library`类表示整个图书馆，包含一个`Book`类型的数组和一些基本的操作，如添加书籍和列出所有书籍。

在主函数中，我们使用一个循环来不断读取用户输入的选项，并执行相应的操作。用户可以选择添加一本书籍、列出所有书籍或退出系统。
