pretty much where i have many of my comments are where i need to call the functions from the player and cell class in the tictactoe class? anyone have any ideas on how to do this?

#include <iostream>

			if (gameEnded)
			{
				myTicTacToe.displayBoard();// problem need to change something in the displayboard function

			} else

Create a new variable of type Player class, make sure the function for solving your problems are PUBLIC methods, and then do var.MethodName(params);

So in Player class, if you had a function like this:

public int PlayerTurn()
{
return playerTurn;
}

in TicTacToe, you would do this:

Player myPlayer = new Player();
myPlayer.PlayerTurn();

cool. just some questions. is there any way to do this by referencing and second do i need to state new before Player():

Out of curiosity, why do you create another tic-tac-toe object within the tic-tac-toe class?

To call the methods of the other class just instantiate it:

MyOtherClass myinstance;
myinstance.methodNeeded();

(since you don't need pointers in this case you can put that on hold for a while)

Player myPlayer = new Player();

If you are going to do it that way it would be Player * myPlayer = new Player(); myPlayer->PlayerTurn();

thats it? really? dam so simple lol. that would work with no compiler errors?

If you are going to do it that way it would be Player * myPlayer = new Player(); myPlayer->PlayerTurn();

so in that sense thats how you use the pointer with class to reference to the functions?

that would work with no compiler errors?

Only one way to find out. Yes, it should. It's the same thing you did with TicTacToe within its own class (which you should still look into btw).

With a pointer to a class, yes, that's how you would access its methods.

ok cool. im gonna run it through the compiler right now

im gettin some errors maybe i did somethin wrong...
i put the errors i get at the end

In between lines 3-5 at the top, forward declare Cell and Player with

class Cell;
class Player;

or move their information up above TicTacToe but this is probably neater.

that still didnt work. i get the same errors

Actually it did take care of some of the problems. However you have an interesting problem on your hands. Because your board is an array of Cells you need to have an overloaded == operator in your Cell class to be able to compare the spots on the board. It doesn't seem like you're to that point yet so you may have to redesign a little bit.

ok im gonna try that

You need the != one too but that's just the NOT of the ==

You need the != one too but that's just the NOT of the ==

can u elaborate a little more about what u mean overloading the == operators in the cell class

Flip ahead a few chapters in your text and it should be there. I'm concerned that your instructor may not want you to use it yet. Basically you use the operator keyword to redefine what == means for your class (essentially your example breaks down to comparing two characters).
I think your best bet would be to just make your board an array of char instead of an array of cells.

ok no problem. im just gonna meet with my instructor tomorrow cause im, to put it simply, stuck lol. thanks for your help tho. i appreciate it

No problem, I mean I would take you through it all but you're probably not quite that far in the material yet. I looked around for a good straightforward tutorial on just the == operator and couldn't find one. It's always best to see what the instructor wants.

Well , for a good portion of those errors, you must INCLUDE the player class's header file, #include "Player.h" I presume, that would fix some errors I THINK. For the other errors, what up with the circumflex accent, and a few questions, did you get this code off of somewhere, because if you made this, then you should know how to use classes :D.

you must INCLUDE the player class's header file, #include "Player.h"

Agreed but I think he has them all laid out in one file.

what up with the circumflex accent

I've seen that on here before. I think if your compiler gives output with the word processor style angled quotes it's a character above 127 so the encoding gets messed up. Not sure where in the process that occurs.

oh ok I see :D
