GNU C++ Regex

HELP!

Can anyone help me? I am relatively new to C++ programming on Linux and I need to know the easiest way to use Regular Expressions.

If anyone can help me and possibley supply some examples, that would be great

Cheers

I think that you better look into perl or python if you have to work exclusively on regular expressions. As for C++, you can look for bruce eckel's book Thinking in C++ in www.mindview.net for some info, if I remember correctly.

Nah, that too easy, I canm allready code Perl, Python, PHP and JAVA.....just need C++

thanks for the links though....haven't found any references to Regex yet but will keep looking

I would not know if there were standard classes for C++ for handling regular expressions, but for C there are. As you probably know, you can use C-functions in C++ without problems.

In C you need too "compile" a regexp using the function regcomp().
The "compiled" regexp can then be used to match strings with regexec().

See:
$ info -f libc "regular expressions"
and/or:
$ man regcomp
$ man regexec

there are couple of regular expression libs.
http://ourworld.compuserve.com/homep...ck/regexpp.htm
and there is one from gnu software check their page but as usual it is written in c not c++ but you can still use it

The C++ Boost library has a regex stuff. Have a look at http://www.boost.org/libs/regex/index.htm.

C++ Boost is a good thing to be familiar with if you're a C++ programmer.
