VC++建筑工地信息管理系统设计

1、建筑工地信息管理系统一题目要求建立如下四个文件（括号为文件中每条记录得字段容）：（1） 销售商一配件一建筑工地（建筑商，配件号，工地号，数量）（2）建筑工地（工地号，名字，城市）（3）配件（配件号，配件名，颜色，重量，产地）（4）销售商（，名字，状态，城市）功能：（1）首先建立文件，然后插入数据，并进行删除，更新操作，最后进行查询操作。（2）查询与供应商所在城市相同的零件一供应商，项目一供应商记录对。二需求分析根据题目要求，由于销售商一配件一建筑工地，建筑工地，配件，销售商的各种信息要求以文本文件的方式存放在四个文件中，所以应提供文件的输入， 输出等操作；在程序中要浏览销售商一配件一建筑工地，

2、建筑工地，配件，销售商的各种信息，应提供显示，查找， 增加，更新等操作；另外还应提供键盘式选择菜单实现功能选择。三总体设计我们来分析一下整个系统，根据上面的需求分析，可以将这个系统的设计分为如下五大 模块：输入，修改，删除，查询，退出。其中输入，修改，删除，查询是四个主要功能。 四详细设计1 定义结构体#in clude<stdio.h> #in clude<stdlib.h> #in clude<stri ng.h> struct total char b_num20;/* 销售商 */char p_num20;/* 配件号 */char num20;/*
