This program is one designed to allow two users to play the classic game of Tic Tac Toe from the command line.
The game of Tic Tac Toe consists of a 3-by-3 grid, two players, and two sets
of tokens, one set for each player (typically 'X's, and 'O's). The players take
turns placing one of their assigned tokens in an unoccupied cell (in the grid)
of their choice. The first player to place 3 of their tokens in a row
(vertically, horizontally, or diagonally) wins the game. If the grid fills up
before either player can place 3 in a row, the game is tied, and is called a
cat game.
The grid is displayed to the console via ASCII characters. Each cell is labeled by a coordinate between 1 and 9. The console prompts the user to enter the coordinate of a cell in which they would like to place their token, and the grid is updated. The winner is then announced when either player wins the game, or announces a 'cat game' if the game is a tie.
If the user would like to quit the game, they may enter a lowercase q when
prompted for their next move. This will quit the game.
- Each token must be placed in a single cell on a grid, defined by a coordinate 1-9.
- A token may not be placed on a cell occupied by another token.
- Any input outside the set of single integers between
1and9will cause an error, and will prompt the user again. - The user may also enter a lowercase
qto end the game.
Below is the initial grid shown at the beginning of each game. Each number represents the coordinate assigned to that cell in the grid.

X - Which square? [1-9] :
================================================================================
The player who's turn it is, is represented at the beginning of the prompt by
an X or O (in this case, it is player Xs turn).
If player 'X' were to enter a 5 to the console when prompted, the board would
be updated, and an 'X' would appear in cell 5. Player 'O' would then be prompted
for his turn.
