定义一个包含图书信息（书号、书名、价格）的链表，读入相应的图书数据来完成图书信息表的创建。然后，统计图书表中的个数，同时逐行输出每本图书的信息。 完整代码

我会尽力回答您的问题，以下是一个 C++ 实现的包含图书信息的链表：

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

struct Book {
    string book_id;
    string book_name;
    double book_price;
    Book* next;
};

Book* create_book_list(int n) {
    Book* head = new Book;
    head->next = nullptr;
    Book* p = head;

    for (int i = 1; i <= n; ++i) {
        Book* q = new Book;
        cout << "Please enter book id, book name, book price for book " << i << ":" << endl;
        cin >> q->book_id >> q->book_name >> q->book_price;
        q->next = nullptr;
        p->next = q;
        p = q;
    }

    return head;
}

void print_book_list(Book* head) {
    Book* p = head->next;
    while (p) {
        cout << p->book_id << " " << p->book_name << " " << p->book_price << endl;
        p = p->next;
    }
}

int count_book_list(Book* head) {
    int count = 0;
    Book* p = head->next;
    while (p) {
        ++count;
        p = p->next;
    }

    return count;
}

int main() {
    cout << "Please enter the number of books:" << endl;
    int n;
    cin >> n;
    Book* head = create_book_list(n);

    int book_count = count_book_list(head);
    cout << "There are " << book_count << " books in the book list." << endl;

    cout << "The book list is:" << endl;
    print_book_list(head);
    return 0;
}

以上代码可以创建一个包含图书信息的链表，并输出每本图书的信息。
