VC++建筑工地信息管理系统

VC++建筑工地信息管理系统VC++建筑工地信息管理系统VC++建筑工地信息管理系统VC++建筑工地信息管理系统编制仅供参考审核批准生效日期地址：电话：传真:邮编:建筑工地信息管理系统一题目要求建立如下四个文件（括号内为文件中每条记录得字段内容）：销售商—配件—建筑工地（建筑商号码，配件号，工地号，数量）建筑工地（工地号，名字，城市）配件（配件号，配件名，颜色，重量，产地）销售商（号码，名字，状态，城市）功能：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。查询与供应商所在城市相同的零件—供应商，项目—供应商记录对。二需求分析根据题目要求，由于销售商—配件—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—配件—建筑工地，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#include<>#include<>#include<>structtotal{charb_num[20];/*销售商号码*/charp_num[20];/*配件号*/charnum[20];/*工地号*/charnum2[20];/*销售商为工地提供配件数量*/};structbuilding{charname[20];/*工地名称*/charnum[20];/*工地号*/charcity[20];/*工地所在城市*/};structpeijian{charp_name[20];/*配件名称*/charp_num[20];/*配件号码*/charp_colour[20];/*配件颜色*/charp_weight[20];/*配件重量*/charp_area[20];/*配件产地*/};structbusiness{charb_name[20];/*销售商名字*/charb_num[20];/*销售商号码*/charb_state[20];/*销售状态*/charb_city[20];/*所在城市*/};2.各功能模块设计（1）输入模块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("","a+b"))==NULL){exit(0);}while(flag=='y'){printf("请输入建筑工地名称:");scanf("%s",;printf("请输入建筑工地编号:");scanf("%s",;printf("请输入工地所在城市:");scanf("%s",;fwrite(&build,sizeof(structbuilding),1,fp);printf("是否继续y/n:\n");scanf("%c",&flag);}fclose(fp);}voidadd2(){charflag='y';structpeijianpj;FILE*fp;if((fp=fopen("","a+b"))==NULL){exit(0);}while(flag=='y'){printf("请输入配件名称:");scanf("%s",;printf("请输入配件编号:");scanf("%s",;printf("请输入配件颜色:");scanf("%s",;printf("请输入配件重量:");scanf("%s",;printf("请输入配件产地:");scanf("%s",;fwrite(&pj,sizeof(structpeijian),1,fp);printf("是否继续y/n:\n");scanf("%c",&flag);}fclose(fp);}voidadd3(){charflag='y';structbusinessbus;FILE*fp;if((fp=fopen("","a+b"))==NULL){exit(0);}while(flag=='y'){printf("请输入销售商名称:");scanf("%s",;printf("请输入销售商编号:");scanf("%s",;printf("请输入销售商状态:");scanf("%s",;printf("请输入销售商所在城市:");scanf("%s",;fwrite(&bus,sizeof(structbusiness),1,fp);printf("是否继续y/n:\n");scanf("%c",&flag);}fclose(fp);}voidadd4(){charflag='y';structtotalbpb;FILE*fp;if((fp=fopen("","a+b"))==NULL){exit(0);}while(flag=='y'){printf("请输入销售商号码:");scanf("%s",;printf("请输入配件编号:");scanf("%s",;printf("请输入建筑工地编号:");scanf("%s",;printf("请输入销售商为工地提供配件数量:");scanf("%s",;fwrite(&bpb,sizeof(structtotal),1,fp);printf("是否继续y/n:\n");scanf("%c",&flag);}fclose(fp);}voidfind1(){FILE*fp;structbuildingbuild;charflag='y',find;charname[20];if((fp=fopen("","r+w"))==NULL)printf("\n\tThesystemcan'topenthefile!!");while(flag=='y'){printf("请输入您要修改的建筑工地名称:");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("建筑工地名称:%s\n",;printf("建筑工地编号:%s\n",;printf("建筑工地所在城市:%s\n",;printf("请输入建筑工地名称:");scanf("%s",;printf("请输入建筑工地编号:");scanf("%s",;printf("请输入建筑工地所在城市:");scanf("%s",;fseek(fp,-(long)(sizeof(structbuilding)),1);/*文件标记向下*/fwrite(&build,sizeof(build),1,fp);}printf("是否继续:");/*提示是否继续修改另一建筑工地信息*/scanf("%c",&flag);}fclose(fp);/*关闭文件*/}（2）修改模块voidfind2(){FILE*fp;structpeijianpj;charflag='y',find;charname[20];if((fp=fopen("","r+w"))==NULL)printf("\n\tThesystemcan'topenthefile!!");while(flag=='y'){printf("请输入您要修改的配件名称:");scanf("%s",name);find='n';rewind(fp);while((fread(&pj,sizeof(pj),1,fp))==1&&find=='n'){if(strcmp,name)==0){find='y';break;}}if(find=='y'){printf("配件名称:%s\n",;printf("配件编号:%s\n",;printf("配件颜色:%s\n",;printf("配件重量:%s\n",;printf("配件产地:%s\n",;printf("请输入配件名称:");scanf("%s",;printf("请输入配件编号:");scanf("%s",;printf("请输入配件颜色:");scanf("%s",;printf("请输入配件重量:");scanf("%s",;printf("请输入配件产地:");scanf("%s",;fseek(fp,-(long)(sizeof(structpeijian)),1);/*文件标记向下*/fwrite(&pj,sizeof(pj),1,fp);}printf("是否继续:");/*提示是否继续修改另一配件信息*/scanf("%c",&flag);}fclose(fp);/*关闭文件*/}voidfind3(){FILE*fp;structbusinessbus;charflag='y',find;charname[20];if((fp=fopen("","r+w"))==NULL)printf("\n\tThesystemcan'topenthefile!!");while(flag=='y'){printf("请输入您要修改的销售商名称");scanf("%s",name);find='n';rewind(fp);while((fread(&bus,sizeof(bus),1,fp))==1&&find=='n'){if(strcmp,name)==0){find='y';break;}}if(find=='y'){printf("销售商名称:%s\n",;printf("销售商编号:%s\n",;printf("销售商状态:%s\n",;printf("所在城市:%s\n",;printf("请输入名称:");scanf("%s",;printf("请输入编号:");scanf("%s",;printf("请输入状态:");scanf("%s",;printf("请输入所在城市名:");scanf("%s",;fseek(fp,-(long)(sizeof(structbusiness)),1);/*文件标记向下*/fwrite(&bus,sizeof(bus),1,fp);}printf("是否继续:");/*提示是否继续修改另一已存用户信息*/scanf("%c",&flag);}fclose(fp);/*关闭文件*/}voidfind4()/*按销售商号修改*/{FILE*fp;structtotalbpb;charflag='y',find;charnum[20];if((fp=fopen("d:/","r+w"))==NULL)printf("\n\tThesystemcan'topenthefile!!");while(flag=='y'){printf("请输入您要修改的对应对中销售商编号:");scanf("%s",num);find='n';rewind(fp);while((fread(&bpb,sizeof(bpb),1,fp))==1&&find=='n'){if(strcmp(num,==0){find='y';break;}}if(find=='y'){printf("销售商编号:%s\n",;printf("配件编号:%s\n",;printf("建筑工地编号:%s\n",;printf("提供配件数量:%s\n",;printf("请输入销售
