文件操作练习。注意B题的读取不能用struct。
D和谐词汇的题,输入是若干字符串,不以空行结束. 所以 gets(line);    while (line[0]){... gets(line);}就会导致时间超限,代码在等空行,但in数据没有。应改为while(gets(line))。
/*文件练习B题. 读取一个包含7类数据的二进制文件,找到指定部分内容,并正确解释输出。
思路分析:主体框架是读取二进制文件,   while (fread(buffer, buffLen, 1, infile) > 0){...}
因为二进制文件的记录长度是固定的,所以可以计算每条记录的长度,使用fseek直接定位到指定段;
所以用fseek的话,实际只需要读一次就可以。
但是这道题的特殊之处在于,一条记录内是顺序包含7种类型数据,是分多次写入,因此带来的麻烦是
虽然每段内容结构相同,但不能用struct进行整块读取。
因为struct的成员之间有内存空隙;除非源文件本身是用struct格式写入才行。
经测试,struct {含7种变量和数组}的长度为200, 但实际7种变量和数组的总长要小一些.
因此,可以直接定位,但必须分别读取,写出的代码冗长,且容易在变量名和输出格式上出错。
一种办法是:按总长度整块读取到字节数组中,然后再逐个定义对应类型的指针,按间接访问就可格式化解释输出。
例: char buffer[LEN];
int i=0; printf("%c\n", buffer[i]); i++;
short * hdPtr=&buffer[i];  printf("%hd\n", *hdPtr); i+=sizeof(short);
