c语言文件读写遇到的问题

Question

#include <stdio.h>
#include <stdlib.h>

int main()
{
    FILE *fp;FILE *fp2;
    fp=fopen(".//file.txt","w");
    fprintf(fp,"???????????????");
    fclose(fp);
    fp2=fopen(".//file.txt","r");
    printf("0");
    while(!feof(fp2))
    {
        printf("1");
    }
    fclose(fp2);
    return 0;
}

该程序一运行就一直输出1，我在另一个程序也遇到这个问题，需要尽快解决，谢谢各位

Answer 1

#include
#include

int main()
{
char ch;
FILE *fp;FILE *fp2;
fp=fopen(".//file.txt","w");
fprintf(fp,"???????????????");
fclose(fp);
fp2=fopen(".//file.txt","r");
printf("0");
while(!feof(fp2))
{
fread(&ch,1,1,fp2);
printf("%c",ch);
}
fclose(fp2);
return 0;
}

改好了，每次读一个字符，然后打印
