簡易水電費管理系統(tǒng)源程序代碼

1、精心打造簡易水電費管理系統(tǒng)源程序代碼法一：#include<stdio.h>#include<string.h>#include<stdlib.h>struct memberchar no100;char name20;char password20;float wfee;float efee;memb;void newadd(int n) int t,i;fseek(fp,0,SEEK_END);printf(">>新添人數(shù)：");scanf("%d",&t);for(i=0;i<t;i+)

2、 printf("新添第d個成員：")；scanf("%s %s %s %f %f",memb.no,,memb.password,memb.wfee,memb.efee);fwrite(&memb,sizeof(struct member),1,fp);void look(int n) char a100;printf(">>輸入卡號：");scanf("%s",a);int i=0;rewind(fp);while(1) fread(&memb,sizeof(str

3、uct member),1,fp);if(feof(fp)|memb.no=a) break;i+;if(!feof(fp) printf(">> 卡號：")；printf("%sn",memb.no);printf(">> 姓名:");printf("%sn",");printf(">> 水費：");printf("%fn",memb.wfee);printf(">> 電費：")

4、；printf("%fn",memb.efee);elseprintf(">>查無此人 n");；void delete(int n) char c100;printf(">>刪除的卡號:");scanf("%s," c);if(fp1=fopen("temp.bin","wb")=NULL)printf(">>不能建立臨時文件，無法刪除n");rewind(fp);while(1) fread(&memb,si

5、zeof(struct member),1,fp);if(feof(fp) break;if(memb.no!=c)fwrite(&memb,sizeof(struct member),1,fp1);fclose(fp1);fclose(fp);remove("member.bin");rename("temp.bin","member.bin");fp=fopen("member.bin","rb+");main() char a100; char b20;FILE *fp;print

6、f("歡迎進入水電費管理系統(tǒng)n")int i=0,sel=1;if(fp=fopen("member.bin","wb+")=NULL) printf(">> 不能建立 member.bin 文件n");return(0);while(sel!=0) printf("| 1|2|3|4|n");printf("|n");printf("|新添成員|查找個人信息|刪除成員 |退出|n);fseek(fp,0,SEEK_END);scanf("%d

7、”,&sel);switch(sel) case 1:newadd(sel); break;clscr(); exit(0);case 2:printf("請輸入您的卡號：");printf("%s",a);printf("請輸入您的密碼：");puts(b)；while(strcmp(a,memb.no)=0&&strcmp(b,memb.password)=0) look(sel);printf("您的輸入有誤 n"); break;clscr();exit(0);case 3:dele

8、te(sel); break;clscr();exit(0);法二：#include<stdio.h>#include<string.h>#include<stdlib.h>#include<windows.h>#include<conio.h>struct memberchar no100;char name20;char password20;float wfee;float efee;memb;void newadd(int n) int t,i;FILE *fp;fp=fopen("e:member.bin"

10、e(fp);void look(int n) char a100,b20; FILE *fp;int i;fp=fopen("e:member.bin","rb");if(fp=NULL) printf("*");printf(">>輸入卡號：");scanf("%s",a);i=0;rewind(fp);while(1) fread(&memb,sizeof(struct member),1,fp);if(feof(fp)|strcmp(memb.no,a)=0) brea

11、k;i+；if(!feof(fp) printf(">> 卡號：")；printf("%sn",memb.no);printf(">> 姓名:");printf("%sn",);printf(">> 水費：");printf("%fn",memb.wfee);printf(">> 電費：")；printf("%fn",memb.efee);elseprintf("

12、;>>查無此人 n");getch();fclose(fp);void dele(int n) char c100;FILE *fp,*fp1;fp=fopen("e:member.bin","rb");printf(">> 刪除的卡號:");scanf("%s" ,c);if(fp1=fopen("temp.bin","wb")=NULL)printf(">>不能建立臨時文件，無法刪除n");rewind(f

13、p);while(1) fread(&memb,sizeof(struct member),1,fp);if(feof(fp) break;if(strcmp(memb.no,c)!=0)fwrite(&memb,sizeof(struct member),1,fp1);fclose(fp1);fclose(fp);remove("member.bin");rename("temp.bin","member.bin");fp=fopen("member.bin","rb+");m

14、ain() char a100; char b20;int i=0,sel=1;FILE *fp;printf("歡迎進入水電費管理系統(tǒng)n");if(fp=fopen("e:member.bin","wb")=NULL) printf(">> 不能建立 member.bin 文件n");return(0);while(sel!=0) printf("| 1|2|3|4|'n");|n");printf("|n");printf("|新添成員|查找個人信息|刪除成員 |退出fseek(fp,0,SEEK_E
