VC++建筑工地信息管理系統(tǒng)

1、精選優(yōu)質(zhì)文檔-傾情為你奉上建筑工地信息管理系統(tǒng)一 題目要求 建立如下四個文件（括號內(nèi)為文件中每條記錄得字段內(nèi)容）：（1） 銷售商配件建筑工地（建筑商號碼，配件號，工地號，數(shù)量）（2） 建筑工地（工地號，名字，城市）（3） 配件（配件號，配件名，顏色，重量，產(chǎn)地）（4） 銷售商（號碼，名字，狀態(tài)，城市） 功能：（1） 首先建立文件，然后插入數(shù)據(jù)，并進(jìn)行刪除，更新操作，最后進(jìn)行查詢操作。（2） 查詢與供應(yīng)商所在城市相同的零件供應(yīng)商，項目供應(yīng)商記錄對。二 需求分析 根據(jù)題目要求，由于銷售商配件建筑工地，建筑工地，配件，銷售商的各種信息要求以文本文件的方式存放在四個文件中，所以應(yīng)提供文件的輸入，輸出等

2、操作；在程序中要瀏覽銷售商配件建筑工地，建筑工地，配件，銷售商的各種信息，應(yīng)提供顯示，查找，增加，更新等操作；另外還應(yīng)提供鍵盤式選擇菜單實現(xiàn)功能選擇。三 總體設(shè)計 我們來分析一下整個系統(tǒng)，根據(jù)上面的需求分析，可以將這個系統(tǒng)的設(shè)計分為如下五大模塊：輸入，修改，刪除，查詢，退出。其中輸入，修改，刪除，查詢是四個主要功能。四 詳細(xì)設(shè)計1定義結(jié)構(gòu)體#include<stdio.h> #include<stdlib.h> #include<string.h> struct total char b_num20;/*銷售商號碼*/ char p_num20;/*配件號*
