定义一个Book类，包括书名、书号、出版社、定价等数据成员，为其添加构造函数、修改书名、定价的set函数、获取书号的get函数，以及显示图书信息的showBook()成员函数。

在testBook.cpp中，创建一个mian函数，在mian函数中创建两个Book类型的对象，并对各对象初始化，调用showBook()成员函数输出各对象的信息，通过相应的set函数，修改各本书的名称和价格，再输出书的相关信息。。

// Book.h代码：
    #ifndef BOOK_H
    #define BOOK_H
    #include<iostream>
    #include<string>
    class Book
    {
    	public:
    		explicit Book(std::string name, int price, int number, std::string publishing);
    		void setBook(std::string name, int price);
    		int getBook();
    		void ShowBook();
    	private:
    		std::string BookName;
    		double BookPrice;
    		int BookNumber;
    		std::string PubliShing;
    };
    
    #endif
    //Book.cpp代码：
    #include "Book.h"
    #include<iostream>
    #include<string>
    using namespace std;
    Book::Book(string name, int price, int number, string publishing)
    	:BookName(name), BookPrice(price), BookNumber(number), PubliShing(publishing)
    	{
    		//BookName=name;
    	}
    	void Book::setBook(string name, int price)
    	{
    		BookName=name;
    		BookPrice=price;
    	}
    	int Book::getBook()
    	{
    		return BookNumber;
    	}
    	void Book::ShowBook()
    	{
    		cout << "hello,welcome to Book!\n" << BookName <<"   " << BookPrice << "   " << BookNumber << "   "<< PubliShing << endl;
    	}
    
    //testBook.cpp代码：
    #include <iostream>
    #include"Book.h"
    #include<string>
    using namespace std;
    int main()
    {
    	string name;
    	int price;
    	Book Book1("三国演义",25.2,0001,"中华出版社");
    	Book Book2("红楼梦",30.4,0002,"中华出版社");
    	Book1.ShowBook();
    	cout << "请输入你所要修改的书的名字以及价格\n"; 
    	getline(cin,name);
    	cin >> price;
    	Book1.setBook(name, price);
    	cout << "get the name and price of the book" << Book1.getBook() << Book2.getBook() << endl;
    	cout << "intformation about the book\n";
    	Book1.ShowBook();
    	Book2.ShowBook(); 
    }
