C语言课设之建筑工地信息管理系统.doc

C 语 言 课 程 实 习 报 告建筑工地信息管理系统一. 题目要求建筑工地信息管理系统要求要建立与建筑相关的四个文件信息：1)项目2）工地3）配件 4）商家；建立文件以后，根据项目、工地或商家完成各项工作的追加、删除、修改和更新查询操作。二. 需求分析 要求整个系统设计为建筑工地的信息输入、追加、删除、修改、浏览、查询模块。三. 总体设计如示意图：开始菜单输入追加删除修改退出浏览项目工地配件商家查找 插入四. 详细设计1.主函数main()menu();2.菜单menu()int n,w1;doputs(ntt*MENU*n);puts(tt 建筑工地信息系统 nn);puts(tttt1.Enter data);puts(tttt2.Addition data);puts(tttt3.Delete data);puts(tttt4.Modify data);puts(tttt5.Insert data);puts(tttt6.Browse all);puts(tttt7.Browse project);
