描述：现有一名为detail.txt的文本文件，文件格式见detail.txt附件
1、文件以空行分割为不同的部分，每一部分开始于时间如：Fri Dec  5 17:46:15 2003，结束于空行
2、没部分可能包含但不限于：
        NAS-IP-Address（IP地址）
        User-Name（用户名）
        Called-Station-Id（被叫号码）
        Calling-Station-Id（主叫号码）
        Acct-Status-Type（计费状态类型：取值范围：Start,Stop）
        Connection_ID(唯一标识)
        Connect_Time(连接时间)
        Acct-Input-Octets(流入字节数)
        Acct-Output-Octets(流出字节数)
        Acct-Session-Time(时长)
        Timestamp(时间戳)
要求:
0、用UNIX下的C语言编写程序
1、提取Acct-Status-Type取值为Stop的部分
2、按用户名User-Name统计每个用户的时长Acct-Session-Time
3、按用户名User-Name统计每个用户的流量Acct-Input-Octets和Acct-Output-Octets
4、将统计结果存入文件,文件格式要求清除的表示每个用户的总时长,流入量总计,流出量总计,总流量
5、文件要有所有用户的总时长,流入量总计,流出量总计,总流量

不会没有人会吧！

要不楼主先说说你自己的想法

黑暗哭泣

每一段的最后其实是个回车的字符'\n'那个空行就是两个回车。其他自己努力吧。

这样的数据，最好用个数据库管理比较简单效率也比较高
