3/24    newbie programming question: If I try and create an ofstream
        object and it fails, how do I find out why?  Can I use errno
        or do I have to do something different?  Basically I want
        to know how to fill in the fragment below:

        ofstream outf(fileName);
        if (! outf) {
                // print an error message indicating why we failed
                // for fopen I could use perror("open failed because:");
        } // thanks
        \_ ofstream::error()

        \_  which class is this for?

1/18    I own a bunch of NFLX stocks bought at several different periods
        (from high $200 all the way down to $80). I dumped a few and
        still have a few. Why the hell is Reid Hastings still making
        $500,000/year? How do I join the pending NFLX Class Action
        Lawsuit?
