G Write a Tic-Tac-Toe game, which will be played and drawn with text characters on the console. This assignment is based on exercise 8.19, but the specifications here will be more specific.

Hi, you haven't provided a programing language, therefore, we will make the game using python and you can extend it to any programming language using the explanation provided.  

class TicTacToe():

   def __init__(self):

       self.board = '  1 2 3\nA|_|_|_|\nB|_|_|_|\nC|_|_|_|'

       self.position = [0,0,0,0,0,0,0,0,0]

       self.representation = (('A1','A2','A3','B1','B2','B3','C1','C2','C3'),\

                                                 (10,12,14,19,21,23,28,30,32))

       print(self.board)

   def check(self, movement):

       try:

           self.index = self.representation[0].index(movement)

           self.value = self.representation[1][self.index]

           if self.position[self.index] != 0:  

               print('Occupied Position')

               return False # No free space to play

           else:

               return True

       except ValueError:

           print('Invalid Input')

           return False # Input error  

   def printBoard(self, simbol):

       self.simbol = simbol  

       self.board = self.board[:(self.value)]+simbol+self.board[(self.value+1)::]

       print(self.board)

       self.position[self.index] = simbol

game = TicTacToe()

f = 0

while True:

   if f == 0:

       p1 = input("Player1: ").upper()

       status = game.check(p1)

       if status:

           game.printBoard('x')

           f = 1

           victory = input("Player one won? y/n: ").lower()

           if victory == 'y':

               print("Player one wins !!!\nEnd of he game")

               break

   elif f == 1:  

       p2 = input("Player2: ").upper()

       status = game.check(p2)

       if status:

           game.printBoard('o')

           f = 0

           victory = input("Player two won? y/n: ").lower()

           if victory == 'y':

               print("Player two wins !!!\nEnd of he game")

               break

   if not(0 in game.position): #no more possible movments  

       print('End of the game')

       break  

Explanation:

With the init method we define our basic text-board, a position array that stores the movements and a tuple for storing the possible movements and the places in the text-board where the x and o are going to be located. In the check method, we verify that a given movement is possible by checking if the player inputs a valid and free position, finally the print method uses 'symbol' to locate the x or o in the corresponding position. This game doesn't implement an automatic victory checking method instead the players decide whether a player won or not.
