仪器仪表管理系统—语言课程设计

1、C语言课程设计报告仪器仪表管理1.题目要求I.【要求】系统功能的基本要求：(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基本信息(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】数据结构采用结构体。仪器仪表信息包括仪器仪表名、仪器仪表编号、购买时间、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。H.需求分析根据题目要求，需要把仪器仪表信息

2、的的数据存储在文件里，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较简洁，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。本题将main()函数体内的界面选择部分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部分功能模块后能够方便返回到系统界面。【程序】main()menu();菜单部分设计如下:【流程图】menu();voidmenu()intw,n;dosystem("cls");print
