1、- .仪器仪表管理1.题目要求.【要求】 系统功能的根本要求：（1） 新的仪器仪表信息的录入；（2） 在借出、归还、维修时对仪器仪表信息的修改；（3） 对报废仪器仪表信息的删除；（4） 按照一定的条件查询符合条件的仪器仪表信息；查询功能至少应该包括仪器仪表根本信息如仪器仪表名字、仪器仪表编等的查询、按时间点借入时间、借出时间、归还时间查询等（5） 对查询结果的输出。 【提示】 数据构造采用构造体。仪器仪表信息包括仪器仪表名、仪器仪表编号、购置时间、借入时间、借出时间、归还时间、维修时间、状态信息0代表可借出，1代表已借出，2代表正在维修等。.需求分析根据题目要求，需要把仪器仪表信息的的数据存储

2、在文件里，所以需要提供文件的输入输出等操作；在程序中要提供修改，删除，查找等操作；另外还应该提供键盘式选择菜单实现功能选择。2.功能实现设计2.1总体设计仪器仪表管理系统添加查询修改删除退出系统功能模块图2.2详细设计1. 主函数主函数一般设计得比拟简洁，只提供输入输出和功能处理的函数调用。其各功能模块用菜单方式选择。此题将main函数体的界面选择局部语句单独抽取出来作为一独立函数，目的在于系统执行完每局部功能模块后能够方便返回到系统界面。【程序】main()menu();菜单局部设计如下：【流程图】显示一系列功能选项输入n，判断n是否是17 N Y根据n的值调用各功能模块函数 主函数的菜单流

3、程图【程序】main()system(cls);/*清屏*/menu();void menu()int w,n;dosystem(cls);printf(tt WELE TO THE EQUIPMENT MANAGEMENT SYSTEMnnn);printf(nntt=*=nnn);printf(ttt1:Add message of new equipmennn);printf(ttt2:Load the message of all equipmentnn);printf(ttt3:Correct the message of equipmentnn);printf(ttt4:Ddlet

6、操作时发现只有字符型的数据可以在文件中成功被保存，所以此题所有数据一律采用字符型。struct equipchar number4;char name11;char b_time11;char bin_time11;char bout_time11;char giveb_time11;char repair_time11; /*time为下面程序中按时间查找和修改时记录输入的时间*/int state;equM;【注意】equM中的M是仪表仪器个数，程序中采用宏定义的方式，可以随时在源程序宏定义中改，本程序宏定义#define M 50。输入用户要输入仪器的个数n 【流程图】i从0到n1调用输

11、显示所有仪器仪表信息，考虑到记录较多，建议采用分屏显示。显示完所有记录后，用户输入要修改的仪器仪表编号，根据编号查找仪器仪表记录，并提示用户修改该记录的哪局部信息，是仪器仪表的借出时间、归还时间、修理时间还是状态，根据用户选择修改相应信息。让用户选择查询方式number or name流程图输入number or name是否找到此记录 Y N显示找到的记录，调用修改函数提示没有找到返回主菜单询问用户是否继续修改修改模块流程图程序/*修改模块*/void modify()struct equip mod;int t,i,m,w,addr=-1;char number4= , name11= ;
