学生计算机机房管理系统设计

功能：该计算机房共有100台计算机，分为20排，每排5台。管理系统应包含每台计算机一周内的使用全部信息，包括计算机序号、配置、位置、状态、使用情况的历史记录（包括使用者姓名、学号、使用时间段）等。本系统可以模拟学生上机和离开的登记过程，查询机房计算机的使用情况。

分步实施：

1、初步完成总体设计，搭好框架，确定人机对话的界面，确定函数个数；
2、建立一个文件，将相关的信息写入文件中并能显示于屏幕上；
3、能实现学生上机的登记过程模拟；
4、进一步要求：查询机房计算机的使用情况。
5、应用C++面向对象程序设计理念，将功能函数封装到类中。
键

系统还有bug，可以继续扩展。

学生

登陆菜单

登陆

退出

学生菜单

本机信息

查询空机位

退出登陆

各模块之间的调用关系如上图，各模块之间相互调用。在登陆时调用Land_show()函数展示登陆的菜单选择功能，在选择注册功能时，通过文件操作打开student.dat以追加的方式写入。在登陆时调用Land()函数，同样通过文件操作方式打开student.dat，把输入的姓名学号进行对比，同时把登陆者的信息写到Historical.dat中。成功登陆后调用Student_show()函数展示菜单，查看本机信息就调用Show_infomation()函数，在通过文件操作打开configure.dat读取信息，查看空机位就调用see()函数，查看历史纪录就调用Historical()函数，通过文件操作打开Historical.dat读取信息。所有的退出都调用Out_land()函数和Sign_out()函数，Out_land()函数把退出时的时间写到Historical.dat中，调用Sign_out()函数时是登陆不成功退出。

数据结构
本程序中数据结构由结构体数组存储信息，各个功能函数放在function类中。有个别特殊函数需要作为普通函数放在类外面。

struct Pc_Information
{int Pc_numb;//计算机序号string configure;//计算机配置string state;//计算机状态string User_name;//姓名string User_numb;//学号char starte_time[32];char end_time[32];int hang;int lie;
}PC_Information[100];//结构体数组class function  //功能类
{public:int land();//登陆函数int Register();//注册函数int Show_infomation();//本机信息int Find();//查找函数int Historical(string name,string numb);//历史纪录int Out_land();//退出登陆函数int HA, LE;
};
