设计一个书类，能够保存书名、定价、所有书本数和总价

类的头文件：

#pragma once

class bookstore
{
public:
    bookstore(void);
    ~bookstore(void);
    char book_name[10];
    int book_price;
    static int book_num;
    int get_book_sum_price();
    void save_info(char con_name[],int con_price);
    void dis_info();
private:
    static int totle_price;
};

cpp：

#include "stdafx.h"
#include "bookstore.h"
#include <iostream>
#include <string>

using namespace std;

int bookstore::book_num=0;

int bookstore::totle_price=0;

bookstore::bookstore(void)
{
}
bookstore::~bookstore(void)
{
}
void bookstore::save_info(char con_name[10],int con_price)
{
    strcpy_s(book_name,10,con_name);

    book_price=con_price;

    book_num++;

    totle_price=totle_price+con_price;
}

int bookstore::get_book_sum_price()
{
    return totle_price;
}

void bookstore::dis_info()
{
    cout<<"书名："<<book_name<<endl;
    cout<<"书价："<<book_price<<endl;
    cout<<"总数："<<book_num<<endl;
    cout<<"总价："<<bookstore::get_book_sum_price()<<endl;
}

主文件：

#include "stdafx.h"
#include<iostream>
#include"bookstore.h"
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
    bookstore a;
    int key=0;
    for(int i=0;i<100;i++)
    {
        cout<<"请输入书名和书价"<<endl;
        cin>>a.book_name>>a.book_price;
        a.save_info(a.book_name,a.book_price);
        a.dis_info();
        cout<<"按“1”继续录入"<<endl;
        while (1)
        {
            cin>>key;
            if(key==1)
                break;
        }
    }
    return 0;
}
