闲来无事，用C++做了一个图书管理系统，主要有借书、还书、图书管理、用户管理等功能，主要用到的技术有容器和文件，以及类的封装

#include #include #include #include #include #include  using namespace std;class Mybook;class Book; class Book{public: int id;              //书号 char book_name[20];        //书名 int state;            //图书状态 char place[20];          //图书所在位置 char stu_number[20];       //学号 char stu_name[20];        //学生姓名public: Book(); friend class Mybook;}; class User{public: char stu_number[20];        //学号 char stu_name[20];         //学生姓名public: User() {  strcpy(stu_number,"000");  strcpy(stu_name,"0"); } friend class Mybook;}; class Mybook{private: list link_book;       //保存书本信息 list link_user;       //保存用户信息public: int main_menu();          //主菜单 void getmenu();          //获取菜单  int menu();
