面试题:一个面试题！！！！

CHANGES.txt包含了我公司开发人员对一个代码库的修改历史。请用C#（或者java）来编写一个词法分
析(Parse)程序来提取以下要求的字段组成的修改纪录，并将结果写入一个或多个文件中。字段之间(field)用'
&brvbar'分隔。具体分析的结果要求如下：
面试题参考：[http://www.aub.org.cn/]
a) 每个纪录应包含下列字段：
Change ID: 给每项修改记录分配一个唯一的序号。
Changed Date: 提取原始修改记录中的MM/DD/YYYY格式的日期。
Changed By:提取原始修改记录中紧跟在日期之后的开发人员名字。
Summary: 提取原始修改记录中由'*)'给出的修改摘要。
Description: 提取原始修改记录中由'Description:'给出的修改说明。
Purpose: 提取原始修改记录中由'Purpose:'给出的修改目的说明。
Changed Files: 提取原始修改记录中由'Changed Files:'给出的修改文件列表。
Added Files: 提取原始修改记录中由'Added Files:'给出的新增文件列表。
b) 请用'*)'作为一项修改的标示（而不是日期）。因为一个开发人员在同一天可以做多项修改。在同一日期下
的多个'*)'应被分割成多个修改纪录。
c) 在"Description:"下可能会有多项由"-"给出的说明项。
CHANGES.txt内容如下：
Change History:
11/12/2004, Simon
*) Added this file.
11/16/2004, Johnason
*) Support saving TDF file
Changed Files: SystemConfig.cpp/h
Added files: TDF.cpp/h
Description:
- Add NIST_SUPPORT in cls_cls.cfg
- Add cls_nist.cfg. A sample and explaination is put in misc
- Add a new class CTDF, which calls some functions of lscvt.lib
and tdf.lib.
Comments:
- CTDF need to be enhanced. The basic idea is to use a base class for
initing, reading existing TDF file and saving repacked TDF file. No
binding data (a virtual function) in base class. Three new class will
be derived from the base class to bind three kinds of data: from
WinCtrlSet, cls_nist.cfg, images. Then ClsMain and ClsDataEntry can
call different class as they required.

大虾们帮帮忙啊。。。没人会的吗？？感觉这个txt文件没什么好的规律 关注中。。。。 面试题很葛... 该回复
于2008-03-29 06:37:22被版主删除我大概想了下还是有一些规律的:排列的顺序,每个字段的数据格式,Tag标志
都是固定的
Change ID: 给每项修改记录分配一个唯一的序号。
Changed Date: 提取原始修改记录中的MM/DD/YYYY格式的日期。
Changed By: 提取原始修改记录中紧跟在日期之后的开发人员名字。
Summary: 提取原始修改记录中由'*)'给出的修改摘要。 是每条记录固有的 顺序也是固定的

Changed Files: 提取原始修改记录中由'Changed Files:'给出的修改文件列表。
