写的一个图书管理系统 希望大家来改进下
程序代码：
#ifndef BOOK_H
#define BOOK_H
#include <string>
#include <iostream>
#include <vector>
using std::ostream;
using std::istream;
using std::string;

class Book{                 //书类
    public:
    friend void  output_book(std::vector<Book>::iterator &a);
    friend ostream& operator<<(ostream& os,std::vector<Book>::iterator &a);
    Book():Inventory(0),Intended(0){};
    Book(string title,string category,string press,string responsible,string isbn,string seriesname,string keywords,int inventory,int intended=0);
    bool Compare_title(const string& isbn)const;
    bool Compare_isbn(const string& title)const;
    friend istream& operator>>(istream& os,Book &a);
    void edit_Title(string title);
    void edit_Category(string category);
    void edit_Press(string press);
    void edit_Responsible(string responsible);
    void edit_ISBN(string isbn);
    void edit_SeriesName(string seriesname);
    void edit_Keywords(string keyword);
    void edit_Inventory(int inventory);
    string get_Title();
    string get_Category();
    string get_Press();
    string get_Responsible();
    string get_ISBN();
    string get_SeriesName();
    string get_Keywords();
    int get_Inventory();
    int get_Intended();
    void add_Intended();
    void less_Intended();
    void add_Inventory();
    void less_Inventory();
    private:
    string Title;           //题名
    string Category;        //分类
    string Press;           //出版社
    string Responsible;     //责任者
    string ISBN;            //ISBN
    string SeriesName;      //丛书名
    string Keywords;        //主题词
    int Inventory;          //库存
    int Intended;           //预定量
    };
#endif
代码写的有点凌乱  大家将就着看吧。。
希望大家对这个程序提些意见，好下次改进。
