C# To C++

This is nothing big, but i dont understand anything from C++

Could you translate this code to C++ please?
File.WriteAllText(@"test.txt", Regex.Replace(Regex.Replace(File.ReadAllText(@"test.txt"), @"-?(?<!,|\d)(?>\d+)(?!,)", "($&)"), @"-?\d+,\d+", "\"$&\""));

The rough overview is that it's reading in a file, doing a regular expression find and replace, then writing that data back to the file. It really should be broken into a few different lines to be more understandable. I don't know what version of VS you're using, but if you have 2008 or above, you can use TR1 regular expressions for that. And you can always use good old fopen, fread and fwrite for the File IO. (There's plenty of libraries to use though. I'm pretty sure MFC has a CFile class or something.)

I suggest acquainting yourself with C++ first. And not asking people to just 'translate' code for you. We're here to help, not to do the work for you.

You don't understand C++, but you assume it's "nothing big". Also, if you don't understand any C++, what were you going to do with the C++ code (if it were to be translated)?

That one line requires knowledge of C++ file I/O and proper usage of a regular expression library, whether it is <regex> or some other third-party library. To discuss this further in detail is too much for a simple forum response.

Yes, i know what to do with code, but could you please give it to me?

Regular expressions

What's the problem? You were given a link to C++ code that processes a regular expression. As a matter of fact, it is a full example of usage of the class.

Did you think that one line of code in C# means one line of code in C++?
