1번쨰땐 너무 아는게 없어 접고 다시 2차로 만들어봤습니다.
그런데 또 오류가 ㅠㅠ
아니 뭐가 문제인지 ㅠㅠ(책을 한번 대충 줄기만 봤더니 이런일이...)
아무튼 밑이 제가 짠 코드고요 비밀번호 프로그램입니다.
#include <stdio.h>
int main(void)
{
int password, repassword, key, first_password;
int secret;
int key1=1;
FILE *fp;
printf("비밀번호를 가지고 있다면 1을 입력하시오.\n");
scanf("%d", &key);
if (key==key1)
printf("비밀번호를 입력하세요.\n");
scanf("%d", &first_password);
fp = fopen("password1.txt", "r");
fscanf(fp, "%d%d%d", &secret, &password, %repassword);
do
{
if(first_password==password)
printf("비밀=%d", secret);
else;
}
while(first_password==password);
printf("프로그램을 끝내려면 1을 입력하세요.\n");
scanf("%d", &key);
else;
printf("비밀을 적으세요.\n");
scanf("%d", &secret);
fprintf(fp, "%d\n", secret);
do
{
fp = fopen("password1.txt","w");
printf("원하는 비밀번호를 적으세요.\n");
scanf("%d", &password);
printf("비밀번호를 재입력 하세요.\n");
scanf("%d", &repassword);
fprintf(fp, "%d%d\n", password, repassword);
fclose(fp);
}
while(password!=repassword);
do
{
printf("비밀번호를 입력하시오.\n");
scanf("%d", &first_password);
if(first_password==password)
printf("비밀=%d", secret);
else;
}
while(first_password!=password);
printf("프로그램을 끝내려면 1을 입력하세요.\n");
scanf("%d", &key);
return 0;
}
이건 오류에요
