I can't seem to get input validation for my tic tac toe game

I have been trying for hours, but the game won't stop looping the player O. That and it won't keep one player from overwriting their mark on another player on the board. Please help. I'm very close to driving my head through my desk.

This makes no sense. switchPlayer function calls switchPlayer(player); forever and ever (with player always set to 1, I note - never with player set to 2, so it is always player 1 having a turn).
