用c ++进行文件比较 [英] File comparison in c++
问题描述
大家好，
我每次构建程序时都必须对生成的文件进行二进制比较。
例如我的第一个构建我生成一个头文件和数据文件，并将它们存储在引用目录中。下次当我再次构建程序时，我将生成相同的文件，如果它们相同，我必须比较参考目录中的文件。我见过不同的实用程序在命令行上执行文件比较。但是我必须在我的程序中包含这个比较并生成一个文件，如果文件中有任何差异。
有谁可以帮我这个？
PS：我正在研究Visual 2005，它是控制台应用程序。
谢谢。
Hi all,
I have to perform binary comparison of the generated files each time I build my program.
For example in my first build I generate a header file and data file and store them in reference directory. Next time when I build the program again I will be generating the same files and I have to compare the ones in my reference directory if they are same. I have seen different utility programs that performs file comparison on the command line. But I have to include this comparison in my program and generate a file if there are any differences in the files.
Could anyone please help me with this?
P.S: I am working on Visual 2005 and it is console application.
Thanks.

您的程序如何构建文件？
是逐行还是char的char？

And how is ur programm building files?
Is it line by line or char by char?

我的程序为例如，通过系统命令的头文件，它就像带有字符和数字的文本文件。另一方面，创建一个包含ASCII字符的数据文件。每次我构建我的程序时，我运行这些系统命令，并创建新版本的文件。
我想回答你的问题，我的程序是逐行构建的。
我不太明白这个问题。
如果您需要更多信息，请告诉我。
谢谢。
My program generates for example the header file through a system commandand it is like text file with characters and numbers.On the other hand a data file is created containing ASCII characters.Each time I build my program I run these system commands and new version of files are created.
I guess answer to your question, my program is building line by line.
I did not exactly understand the question.
Please let me know if you need more information.
Thanks.

好的，它是逐行的，这意味着你可以创建一个简单的while循环，它将循环直到达到eof并且文件没有更新.In循环你必须测试那些线是否公平，如果新行与文件中的行不同，请将其替换为你的文件。
Savage
Ok so it''s line by line which means that u can create a simple while loop which will loop until eof is reached and files are not updated.In loop body u must test those lines for equlaity and if new line is different from line in file replace it in ur file.
