My problem is this... in a simple C++ game, one can move the aeroplane with the left and right CURSOr keys of the keyboard. In the code, the left key is given a number 19200 and the right key is given a number 19712. I do not know what or where these numbers came from. I plan to improvise on this game by giving the airplane the ability to move up and down as well. However, I do not know the corresponding codes for the up and down keys. Do you know them? Appreciate the help. Thank you.
