c語言實現(xiàn)注冊登陸功能(兩個模塊)

1、精選優(yōu)質(zhì)文檔-傾情為你奉上typedef structchar user20;char code20;USER;void write() /*用戶信息寫入*/if(fp=fopen(pe.user,"w")=NULL)printf("ntt文件打開失敗");if(fwrite(&pe,sizeof(USER),1,fp)!=1)printf("ntt寫入文件錯誤");fclose(fp);void zhuce()char temp20,txt100,cha;int i=0;do printf("tttt用戶注冊&qu

2、ot;);printf("ntt1.直接注冊 2.閱讀用戶手冊");cha=getch();if(cha='2')if(fp=fopen("使用說明.txt","r")=NULL)printf("ntt打開失敗");exit(0);fread(txt,2,20,fp);printf("ntt%s",txt);/*txt=fgets(txt,100,fp);printf("%s",txt);*/printf("ntt按任意鍵繼續(xù)");getc

3、h();system("cls");printf("tttt用戶注冊");printf("ntt用戶名:"); scanf("%s",pe.user);printf("ntt密 碼:"); scanf("%s",pe.code);printf("ntt確認密碼:");scanf("%s",temp);if(strcmp(pe.code,temp)!=0)printf("ntt兩次密碼不一致,請重新輸入"); whil

4、e(strcmp(pe.code,temp)!=0); fp=fopen(pe.user,"r"); if(fp=NULL) fp=fopen(pe.user,"w"); if(fp=NULL) printf("nt注冊失敗n"); exit(0); else system("cls"); printf("nt注冊成功");write();judge = false;denglu(); else printf("nt該用戶名已存在"); fclose(fp); printf(

5、"nt繼續(xù)注冊?(Y/N)"); if(getch()='Y') return zhuce(); else return denglu(); void write()if(fwrite(&pe,sizeof(User),1,fp)!=1) printf("ntt寫入文件錯誤"); exit(0); /寫入錯誤則退出程序 void denglu() char u20,c20,temp20; printf("ntttt用戶登錄"); printf("ntt用戶名:"); scanf("

6、%s",u); fp=fopen(u,"r+"); temp0='0' if(fp=NULL) printf("ntt用戶不存在,請注冊"); printf("ntt1.注冊 2.重新登陸"); temp0=getch(); if(temp0='1')system("cls");zhuce(); else return denglu(); do if(judge=true) fread(&pe,sizeof(USER),1,fp);printf("tt密 碼:"); scanf("%s",c); if(strcmp(pe.code,c)!=0) printf("ntt密碼錯誤(1.退出 2.重新輸入)"); temp0=getch(); printf("n"); if(temp0=&
