e.g.3x3 tic tac toe we'll number them 1,2,3,4,...
could have chosen a 3x3 array but we'll just do 1-9.

also have to take care of x and o
human and computer also.

                     x  or o       goes first
human
computer

we have to allow either to be x or o, and also allow human and computer to be the thing that goes first.


board( ) = 0 for blank
 	1 for human move, this is more fundamental. want to evaluate the best move for the computer
	2 for computer move

so if x in 2 and o in 6


board(2) = 1
board(6) = 2


board =   0 1 0
	  0 0 2
	  0 0 0

to write a subroutine

printboard that will just print out the current state of the board.
contents of board array, etc. what should print to the screen

hint: if you define a character array, x is character not a number...you define a character array cboard(9) and assign elements of it to blank, x, or o and depends on contents of WHAT

subroutine has to have two arguments
1: board
2: player x who determines who is x and who is o
