I have added the header "#include <conio.h>" and also "_getch();" at the end of the code. I am just learning C++, but I have been using this in all of my programs and it seems to work.

(Also, I have received a lot of help from people at D.I.C., that I was hoping I would be able to give back -- even if it's just a little.)

Hope this works for you.
