    Help with regular expression

    Hi!

    I have the following regular expression, that matches any word with
    number and letter:

    [[:alnum:]]+-?[[:alnum:]/@\\.#&]*'?

    Now I must modify it so that also the word with a "_" inside are
    accepted. For example:

    As_for
    From_now_on
    For_example

    Can you help me?
    Thanks in advance.

      This is really off-topic here, since there are no regex in (the current)
      C++ standard, you should ask these kinds of questions in a forum for the
      library you used for regexes. Having said that I think you can get it to
      do what you want with one of the following (I'm no expert at regex and I
      don't recognize the flavour so I give no guarantees):

      [[:alnum:]]+(-|_)?[[:alnum:]/@\\.#&]*'?

      [[:alnum:]]+[-_]?[[:alnum:]/@\\.#&]*'?

          TR1 does include include a regex library, and FAQ 5.9 says questions
          are on-topic if they can be answered by looking at the standard or
          "planned extensions and adjustments" to it. So I'd say both the
          question and your answer are on-topic.

              TR1 does include include a regex library,
              As does C++0x.
