Explanation: Class Definition (ConnectFour): The ConnectFour class manages the game, including the game board, player moves, and win condition checks. Board Initialization: The board is initialized as a 6×7 grid filled with dots (‘.’), representing empty slots. The currentPlayer is set to ‘X’, meaning player X starts the game. Board Printing (printBoard): The printBoard …
