Question

For this assignment, let the Tic Tac Toe game board be stored as a 3 × 3 character array called ‘board.’ For example, at a given point the board might look like the one shown below:

>> board = [ ’ - ’ , ’O ’ , ’X ’; ’ - ’ ,’ - ’ , ’O ’; ’X ’ , ’O ’ , ’ - ’]

board =

3 x3 char array

’ - OX ’

’ --O ’

’XO - ’

Write a Matlab script that displays the current game board to the command prompt. Your code should display whatever happens to be stored in the variable ‘board’ at the time the code is run. In other words, it should not simply display the particular game board shown above.

See sample output below:

>> board = [ ’O ’ , ’X ’ , ’ - ’; ’X ’ ,’O ’ , ’ - ’; ’ -’ , ’ - ’ , ’ - ’ ];

>> problem2

OX -

XO -

Explanation / Answer

Make the board variable global. Do code like this;

>> global board ;

>> board = [ ’O ’ , ’X ’ , ’ - ’; ’X ’ ,’O ’ , ’ - ’; ’ -’ , ’ - ’ , ’ - ’ ];

here the code for your problem2.m script file

%-----problem2.m--------------------

function problem2
global board ;
display(board);

%------------------------------

Now modifile the board

>>board = [ '-' , 'O' , 'X'; 'X' ,'O' , 'X'; 'X' , 'O' , 'M'];

>> problem2

board =

-OX
XOX
XOM
