C语言课设之建筑工地信息管理系统

C语言课设题目：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：四.详细设计1.主函数main(){menu();}2.菜单menu(){int n,w1;doputs("\n\t\t********************MENU********************\n");puts("\t\t 建筑工地信息系统 \n\n");puts("\t\t\t\t1.Enter data");puts("\t\t\t\t2.Addition
