批判 [英] Critique
问题描述
大家好，
哇，自从我向这个
组发布任何东西以来，已经很久了。我不再像过去那样保持现状;当我有空闲时，我只会潜伏在
。
我正在尝试编写程序来打开文件并处理它
根据命令行参数。我只需要两个简单的搜索
和替换操作。我用一个代表一个
站点代码的int和一个表示日期的长调用程序，我的程序应该用int替换
文件中的一些硬编码文本字符串我已经过了很长时间。我可能已经了解了为什么现在不能正常工作，但我会像这里的建设性批评一样。我试图遵循标准
（据我所知），但是，好吧，让我们看看它是怎么回事......感谢阅读！

Hello all,
Wow, has it ever been a long time since I posted anything to this
group. I don''t keep as current as I used to anymore; I only lurk from
time to time when I have a spare moment.
I am trying to write a program to open a file and process it
according to command line parameters. All I need are two simple search
and replace operations. I invoke the program with an int representing a
site code and a long representing a date and my program should replace
some hard-coded text strings in the file with the int and the long I pass
in. I may have some insight as to why this is not working now, but I''d
like some constructive criticism here. I tried to conform to the standard
(as I know it), but, well, let''s see how it goes... Thanks for reading!

从根本上说，你试图把太多的东西塞进一个例行程序中，主要是。
如果你打破行动，情况会更清楚。你的
getline是朝着正确的方向迈出的一步。
但是有可用的代码几乎完全按照你想要的b $ b想要的。看看我的网站上的ggets和id2id-20。 id2id将
如果你写一个两行配置文件来提供你的工作
替换xxx和yyyyyyyy，但这可能不太好
适合。无论如何，便携式信号源都在那里，您可以轻松地将其更改为命令行参数。请参阅：

Fundamentally you try to cram too much into one routine, main.
Things will be much clearer if you break operations up. Your
getline is a step in the right direction.
However there is available code to do almost exactly what you
want. Take a look on my site for ggets and id2id-20. id2id will
do your job if you write a two line configuration file to supply
the replacements for xxx and yyyyyyyy, but this may not be quite
suitable. At any rate the portable source is there, and you can
easily change it to work from command line parameters. See:

有人同意这个观点吗？在

实施的负担;更具体地说，它允许我
总是将main（）作为第一个函数。为此，我愿意以小而无害的冗余形式支付

Does anyone agree with this notion? Having separate prototypes at the top of
a file relieves me of the burden of having to arrange my function
implementations in a specific order; more specifically, it allows me to
always have main() as the first function. For that, I am willing to pay a
price in the form of a small, innocuous redundancy.
