tic tac toe Class, printing a 2D Array board issue

rogermaris (2)
I'm not sure what I'm doing. Any suggestions will be greatly appreciated.

I have to make a tic tac toe class. First obstacle, print a 2D array. I’m trying to get this set up one function at a time.

Main hindrance:I keep getting this wicked compiling error

printtest.cpp: In function ‘int main()’:
printtest.cpp:20: error: expected primary-expression before ‘char’


This makes it so I can't verify if I am on the right track to finish the rest of my class. If I can figure out how to do this, I think I'll be able to finish the rest of tic tac toe class.

heres all 3 files TTT.h TTT.cpp printtest.cpp

On line 62: You can't pass parameters to a function like that. You need to create the board, then pass it:

char board[3][3]
TTT1.printboard(board);

thanks, it compiled! Unfortunately, This leds me into a different problem. this is the result:

-|-|-

-|-|-
K
-|-|-



not sure how to make it look like a standard tictactoe board given my code. It always turns out all scrambled like above.
Heres an update of my code:

updated with attempt to initialize. As you see I am new at OOP, I mean I don't even know if this is the proper way to input this initialization.

Did you initialize the array? If you didn't, it will (probably) be full of garbage data like K's and question marks.
