我用下面的语句读取文件内容，文件内容如下：
01001
C语言程序设计
1
C语言程序的基本单位是
A 程序行 B 语句 C 函数 D 字符
C
0


为什么第五行的A读不出来，是不是我下面的程序行有问题呢？

        fscanf( fp1, "%s", question.order );
        fscanf( fp1, "%s", question.tip );
        fscanf( fp1, "%d", &question.level );

        i = 0;
        fgetc( fp1 );
        while( ( c = fgetc( fp1 ) ) !='\n' )
            question.content[i++] = c;
        question.content[i] = '\0';
        
        i = 0;
        fgetc( fp1 );
        while( ( c = fgetc( fp1 ) ) !='\n' )
            question.choices[i++] = c;
        question.choices[i] = '\0';

        fscanf( fp1, "%c", &question.answer );
        fscanf( fp1, "%d", &question.times );
