Tic Tac Toe in C++

By Hritwick Manna

Designing a tic-tac-toe player (CPU) that never loses, and wins whenever possible. This programme has used basic concepts like conditionals, loops, jumps, functions.

Description:

Our program first asks whether the user chooses to be Player 1 or Player 2. The symbols in the grid for players 1 and 2 will be X and O respectively. As a move, the player will be expected to input a number from 1 to 9, considering the cells in the top, middle, and bottom rows to be numbered 1-3, 4-6, and 7-9 from left to right, respectively.  After each move, Our program displays the tic-tac-toe grid in the terminal. For example, a typical state of the game could look like this:

   | O | X
------------
   |   | 
------------
 X |   |

 

The game concludes when a player wins, or all the cells are filled if it is a draw. After the conclusion of a game, the program asks the user whether he wants to play another game or not, and proceed accordingly.
