VC建筑工地信息管理系統(tǒng)

/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）：銷售商—配件—建筑工地（建筑商號碼，配件號，工地號，數(shù)量）建筑工地（工地號，名字，城市）配件（配件號，配件名，顏色，重量，產(chǎn)地）銷售商（號碼，名字，狀態(tài)，城市）功能：首先建立文件，然后插入數(shù)據(jù)，并進行刪除，更新操作，最終進行查詢操作。查詢和供應商所在城市相同的零件—供應商，項目—供應商記錄對。二需求分析依據(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，所以應供應文件的輸入，輸出等操作；在程序中要閱讀銷售商—配件—建筑工地，建筑工地，配件，銷售商的各種信息，應供應顯示，查找，增加，更新等操作；另外還應供應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)，依據(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。四具體設(shè)計1．定義結(jié)構(gòu)體#include<stdio.h>#include<stdlib.h>#include<string.h>structtotal{charb_num[20];/*銷售商號碼*/charp_num[20];/*配件號*/charnum[20];/*工地號*/charnum2[20];/*銷售商為工地供應配件數(shù)量*/};structbuilding{charname[20];/*工地名稱*/charnum[20];/*工地號*/charcity[20];/*工地所在城市*/};structpeijian{charp_name[20];/*配件名稱*/charp_num[20];/*配件號碼*/charp_colour[20];/*配件顏色*/charp_weight[20];/*配件重量*/charp_area[20];/*配件產(chǎn)地*/};structbusiness{charb_name[20];/*銷售商名字*/charb_num[20];/*銷售商號碼*/charb_state[20];/*銷售狀態(tài)*/charb_city[20];/*所在城市*/};2.各功能模塊設(shè)計（1）輸入模塊voidadd1();voidadd2();voidadd3();voidadd4();voidfind1();voidfind2();voidfind3();voidfind4();voiddel1();voiddel2();voiddel3();voiddel4();voidseek1();voidseek2();charflag='y';intn;voidadd1(){charflag='y';structbuildingbuild;FILE*fp;if((fp=fopen("c.txt","a+b"))==NULL){exit(0);}while(flag=='y'){printf("請輸入建筑工地名稱:");scanf("%s",);printf("請輸入建筑工地編號:");scanf("%s",build.num);printf("請輸入工地所在城市:");scanf("%s",build.city);fwrite(&build,sizeof(structbuilding),1,fp);printf("是否接著y/n:\n");scanf("%c",&flag);}fclose(fp);}voidadd2(){charflag='y';structpeijianpj;FILE*fp;if((fp=fopen("d.txt","a+b"))==NULL){exit(0);}while(flag=='y'){printf("請輸入配件名稱:");scanf("%s",pj.p_name);printf("請輸入配件編號:");scanf("%s",pj.p_num);printf("請輸入配件顏色:");scanf("%s",pj.p_colour);printf("請輸入配件重量:");scanf("%s",pj.p_weight);printf("請輸入配件產(chǎn)地:");scanf("%s",pj.p_area);fwrite(&pj,sizeof(structpeijian),1,fp);printf("是否接著y/n:\n");scanf("%c",&flag);}fclose(fp);}voidadd3(){charflag='y';structbusinessbus;FILE*fp;if((fp=fopen("e.txt","a+b"))==NULL){exit(0);}while(flag=='y'){printf("請輸入銷售商名稱:");scanf("%s",bus.b_name);printf("請輸入銷售商編號:");scanf("%s",bus.b_num);printf("請輸入銷售商狀態(tài):");scanf("%s",bus.b_state);printf("請輸入銷售商所在城市:");scanf("%s",bus.b_city);fwrite(&bus,sizeof(structbusiness),1,fp);printf("是否接著y/n:\n");scanf("%c",&flag);}fclose(fp);}voidadd4(){charflag='y';structtotalbpb;FILE*fp;if((fp=fopen("f.txt","a+b"))==NULL){exit(0);}while(flag=='y'){printf("請輸入銷售商號碼:");scanf("%s",bpb.b_num);printf("請輸入配件編號:");scanf("%s",bpb.b_num);printf("請輸入建筑工地編號:");scanf("%s",bpb.num);printf("請輸入銷售商為工地供應配件數(shù)量:");scanf("%s",bpb.num2);fwrite(&bpb,sizeof(structtotal),1,fp);printf("是否接著y/n:\n");scanf("%c",&flag);}fclose(fp);}voidfind1(){FILE*fp;structbuildingbuild;charflag='y',find;charname[20];if((fp=fopen("c.txt","r+w"))==NULL)printf("\n\tThesystemcan'topenthefile!!");while(flag=='y'){printf("請輸入您要修改的建筑工地名稱:");scanf("%s",name);find='n';rewind(fp);while((fread(&build,sizeof(build),1,fp))==1&&find=='n'){if(strcmp(name,)==0){find='y';break;}}if(find=='y'){printf("建筑工地名稱:%s\n",);printf("建筑工地編號:%s\n",build.num);printf("建筑工地所在城市:%s\n",build.city);printf("請輸入建筑工地名稱:");scanf("%s",);printf("請輸入建筑工地編號:");scanf("%s",build.num);printf("請輸入建筑工地所在城市:");scanf("%s",build.city);fseek(fp,-(long)(sizeof(structbuilding)),1);/*文件標記向下*/fwrite(&build,sizeof(build),1,fp);}printf("是否接著:");/*提示是否接著修改另一建筑工地信息*/scanf("%c",&flag);}fclose(fp);/*關(guān)閉文件*/}（2）修改模塊voidfind2(){FILE*fp;structpeijianpj;charflag='y',find;charname[20];if((fp=fopen("d.txt","r+w"))==NULL)printf("\n\tThesystemcan'topenthefile!!");while(flag=='y'){printf("請輸入您要修改的配件名稱:");scanf("%s",name);find='n';rewind(fp);while((fread(&pj,sizeof(pj),1,fp))==1&&find=='n'){if(strcmp(pj.p_name,name)==0){find='y';break;}}if(find=='y'){printf("配件名稱:%s\n",pj.p_name);printf("配件編號:%s\n",pj.p_num);printf("配件顏色:%s\n",pj.p_colour);printf("配件重量:%s\n",pj.p_weight);printf("配件產(chǎn)地:%s\n",pj.p_area);printf("請輸入配件名稱:");scanf("%s",pj.p_name);printf("請輸入配件編號:");scanf("%s",pj.p_name);printf("請輸入配件顏色:");scanf("%s",pj.p_colour);printf("請輸入配件重量:");scanf("%s",pj.p_weight);printf("請輸入配件產(chǎn)地:");scanf("%s",pj.p_name);fseek(fp,-(long)(sizeof(structpeijian)),1);/*文件標記向下*/fwrite(&pj,sizeof(pj),1,fp);}printf("是否接著:");/*提示是否接著修改另一配件信息*/scanf("%c",&flag);}fclose(fp);/*關(guān)閉文件*/}voidfind3(){FILE*fp;structbusinessbus;charflag='y',find;charname[20];if((fp=fopen("e.txt","r+w"))==NULL)printf("\n\tThesystemcan'topenthefile!!");while(flag=='y'){printf("請輸入您要修改的銷售商名稱");scanf("%s",name);find='n';rewind(fp);while((fread(&bus,sizeof(bus),1,fp))==1&&find=='n'){if(strcmp(bus.b_name,name)==0){find='y';break;}}if(find=='y'){printf("銷售商名稱:%s\n",bus.b_name);printf("銷售商編號:%s\n",bus.b_name);printf("銷售商狀態(tài):%s\n",bus.b_state);printf("所在城市:%s\n",bus.b_city);printf("請輸入名稱:");scanf("%s",bus.b_name);printf("請輸入編號:");scanf("%s",bus.b_num);printf("請輸入狀態(tài):");scanf("%s",bus.b_state);printf("請輸入所在城市名:");scanf("%s",bus.b_city);fseek(fp,-(long)(sizeof(structbusin
