C++ open multiple files one by one?

C++ open multiple files to read from in?
I didn't ask the question the way I should have asked it earlier
here is original http://answers.yahoo.com/question/index;_ylt=AjNoITYaimqYoPaJ_KqICwrsy6IX;_ylv=3?qid=20080525213222AAR6dsY

Anyway, so I have blah1.txt, myname.txt somestuff.txt and so on. How do
I open them one by one, and believe me I googled to find a working
script on this and tried many concepts. What I do now is that I can't
pass a string into the () as you'll see on link which is why I'm
clueless and the BOOST method doesn't work for me because I don't have
boost.

I looked all over on net and couldn't find any sample code to do this,
2 days now and still don't get it and I found two that lets me list the
directories, in my opinion really close.

but nothing to open them 1 by 1. I really don't think there is a standard on this but it sounds so simple. Appreciate any help.
