ok i know this is really dumb but im trying to make a tic tac toe game (using matrices, which work, so thats not the problem) and i need to use a string or two here and there, and it doesnt wanna let me use em =/, here is the code for the game itself (even though i prolly dont need to include it in this case...) and below that are the errors i get when building
