u语言 设计并实现一个图书信息管理系统。根据实验要求设计该系统的菜单和交互逻辑，并编码实现增删改查的各项功能。该系统至少包含以下功能:(1)根据指定图书个数，逐个输入图书信息;(2)逐个显示图书表中所有图书的相关信息;(3)将新图书插入到图书表中指定的位置:(4)将该图书从图书表中删除:(5)能统计表中图书总数; (6)使用排序算法按照图书价格降序排序:

以下是一个可能的设计和实现，可以根据具体需求和编程语言进行适当调整： ```python class Book: def __init__(self, title, author, price): self.title = title self.author = author self.price = price class BookInfoManagementSystem: def __init__(self): self.books = [] def add_book(self, book): self.books.append(book) def display_all_books(self): for book in self.books: print(f"Title: {book.title}, Author: {book.author}, Price: {book.price}") def insert_book(self, position, book): self.books.insert(position, book) def delete_book(self, book): self.books.remove(book) def count_books(self): print(f"Total number of books: {len(self.books)}") def sort_books_by_price(self): self.books.sort(key=lambda x: x.price, reverse=True) if __name__ == "__main__": book_management_system = BookInfoManagementSystem() num_of_books = int(input("Enter the number of books: ")) for _ in range(num_of_books): title = input("Enter book title: ") author = input("Enter author name: ") price = float(input("Enter book price: ")) new_book = Book(title, author, price) book_management_system.add_book(new_book) book_management_system.display_all_books() position = int(input("Enter the position to insert new book: ")) new_book = Book("New Book", "New Author", 10.99) # Example new book book_management_system.insert_book(position, new_book) book_management_system.display_all_books() book_management_system.delete_book(new_book) book_management_system.display_all_books() book_management_system.count_books() book_management_system.sort_books_by_price() book_management_system.display_all_books() ``` 在这个示例中，我们定义了一个 `Book` 类来存储图书信息，然后实现了一个 `BookInfoManagementSystem` 类来管理图书信息。该系统包含了增加、显示、插入、删除、统计和排序等功能。用户可以通过交互界面输入图书信息和操作命令来使用该系统。 [2024-07-01 00:40:26 | AI写代码神器 | 1374点数解答]
