这段代码有一些问题，比如在类的成员函数中使用了字符指针而不是字符串，还有构造函数和成员函数的参数顺序不一致。下面是修改后的代码：

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

class Book {
private:
    string bookname;
    string authtors;
    string publishing_house;
    int pages;
    double price;

public:
    Book() {
        bookname = "";
        authtors = "";
        publishing_house = "";
        pages = 0;
        price = 0;
    }

    Book(string bk, string auth, int pag, string pub, double pri) {
        bookname = bk;
        authtors = auth;
        pages = pag;
        publishing_house = pub;
        price = pri;
    }

    ~Book() {}

    string getBookname() const {
        return bookname;
    }

    void setBookname(string name) {
        bookname = name;
    }

    string getAuthtors() const {
        return authtors;
    }

    void setAuthtors(string auth) {
        authtors = auth;
    }

    string getPublishing_house() const {
        return publishing_house;
    }

    void setPublishing_house(string pub) {
        publishing_house = pub;
    }

    int getPages() const {
        return pages;
    }

    void setPages(int pag) {
        pages = pag;
    }

    double getPrice() const {
        return price;
    }

    void setPrice(double pri) {
        price = pri;
    }
};

int main() {
    Book book1("《C++程序设计》", "谭浩强编著", 485, "清华大学出版社", 36.00);
    Book book2("《吹牛大王历险记》", "拉斯伯等编著", 149, "天津人民出版社", 12.80);

    cout << "书名：" << book1.getBookname() << endl;
    cout << "作者：" << book1.getAuthtors() << endl;
    cout << "页数：" << book1.getPages() <<"页"<< endl;
    cout << "出版社：" << book1.getPublishing_house() << endl;
    cout << "价格：" << book1.getPrice() <<"元"<< endl;
    cout << endl;
    cout << "书名：" << book2.getBookname() << endl;
    cout << "作者：" << book2.getAuthtors() << endl;
    cout << "页数：" << book2.getPages() << "页" << endl;
    cout << "出版社：" << book2.getPublishing_house() << endl;
    cout << "价格：" << book2.getPrice() << "元" << endl;

    return 0;
}

这个修改后的代码使用了字符串来代替字符指针，并将参数顺序保持一致。这样代码更加清晰易读，并且更符合 C++ 的编程风格。
