Question

Need C++ code for following with a document describing the code as well:

Write a program to implement the game of Tic Tac Toe Four.

The game is played on a 4 × 4 chessboard, within 2 players. The player who is playing "X" always goes first. Players alternate placing Xs and Os on the board until either one player has four in a row, horizontally, vertically, or diagonally; or all 16 squares are filled(which is a draw).

The program should be able to:

1) keep receiving the input from two players in turn.

E.g. receive both row index and column index from keyboard input

2) print the current chessboard pattern for every turn. Below is an example of chessboard printing, with ‘-’ for empty squares. You can use any other pattern you like to visualize the chessboard.

- - - - - - - - - - - - - - - - game start

- - - - - - x - - o - - - - - - during game

- - - - - x x - - o - - - - o - during game

o o o o - x x - - o - x x - o x “o” wins

3) determine if any player wins the game, or the game comes to a draw. Print out the final game result.

E.g. “Player1 wins” or “Draw”

Please submit all your source codes together with a document describing your code and ideas
