You'll want to use the opendir() and readdir() functions to read

Despite what you may be told, C's printf is still, in my opinion, the
easiest way to produce neatly-formatted output in C++.

^L (\f, if I remember correctly) is a formfeed character.  The printed 
page is 66 lines; the screen is 24 lines.

Watch out with arrays; if you get more data than you expect, your
program will crash.  You may want to use a linked list instead.  Or,
better yet, read in one item at a time and output the results as you
read them in.
