Tic-Tac-Toe is a two player game where each player uses a signature. The player who successfully places three respective signatures in a vertical, horizontal or diagonal row is the winner.
Step 1: Use 3 X 3 matrix to get 9 cell tic tac toe board.
Step 2: Signature 'X' is used for player 1 and 'Y' for player 2. And the players play
alternatively.
Step 3: Get index as input from the players. And the index range is 1-9. i.e) from
cell 1 to cell 9.
Step 4: After each move, check whether that player has placed three respective
signatures in vertical, horizontal or diagonal row. If yes, declare that
particular player as winner.
Step 5: If no, give chance for other player.
Step 6: If all the cells in the Tic-Tac-Toe board got filled, then the game is drawn.

This is TicTacToe...otherwise known as Noughts and Crosses and should be played with the markers "X" & "O", not "Y"!
ReplyDeleteTo fix this change..sign = 'Y'; to sign = 'O'; and (data[index - 1] == 'X' || data[index - 1] == 'Y') to (data[index - 1] == 'X' || data[index - 1] == 'O')...Thanks for the code and happy tictactoe playing :-)
