    Regular Expressions

    If I want to search a string for a sequence that is followed by a "?" (ex. abc?), how could I do this? I was having trouble with it because that is used to signify types of regular expressions.

    we're talking about on unix? If I understand your question correctly you need to "escape" it.

    ex...

    *\?

    You could probably use regular expressions, but why not .Split( "?" ) the string ?

    When in doubt, read the FAQ.
    Then ask a smart question.

    Are you using '@' to preceed the string defining your regex pattern?

    you could use a finite state machine.
    Code:
    bool fun(bool value)
    {
        return std::pow(std::exp(1), std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1)*(1 << (value + 2))))
        .real() > 0;
    }
