Hello, I hope that I wraped the code correctly. I am trying to get this TTT game to work. I fixed all errors accept it says on lines
32, 34,42-45 "expected primary-expression before ']' token "
Help, hanks, VERMUNDr

Did you try using passing matrix as matrix[3][3] instead of matrix[][3]? I don't know if it would help or not, but it's worth a shot as I remember possibly encountering the same problem.

Yeah, now it says "initializing argument 2 of `void checkPlayerWin(bool&, char (*)[3])' "and"invalid conversion from `char' to `char (*)[3]' "

Simply pass the array in as matrix each time without any of the brackets. You've already designated that the function is taking an argument that's a matrix with 2 dimensions in the prototype and definition. When it comes to the definition of the function, the array being passed into a function degrades to a pointer. Passing in matrix[][N] gives a pointer to the array that holds each of the rows of the 2D matrix, not the entire thing.

Thanks much. I knew it was something silly & simple.

The matrix works now. The board does not update and the computer can't play......

The matrix works now. The board does not update and the computer can't play......

shows move now, but still can't get it to go on to the computer's turn....... due soooon

update the code -,-? i tried it 5 minutes ago and it still has those compile errors
