Write the main, ReadBoard, Show_GameState, Winner, PlayerMarks Write the C++ CODE. Purpose: Write a C++ program to accept a string that encodes the markings on a 3x3 tic-tac-toe board. The program must display the 2-dimensional tic-tac-toe board. The program must also announce the state of the game: NEW GAME -- when the board is empty. WINNER IS X -- when player X is the winner. WINNER IS O -- when player O is the winner. IN PROGRESS -- when no player has won and game not completed. DRAW -- when no player has won, and game is completed. Specification: +--------------+ | | | program | board_markings | |--------> game_status ------------->| tictactoeA | | |--------> tictactoeBoard | | +--------------+ Examples (Test Cases): Board Markings: BBBBBBBBB GAME STATUS: NEW GAME GAME BOARD: ---+---+--- | | ---+---+--- | | ---+---+--- | | ---+---+--- Board Markings: XBXBOOOBX GAME STATUS: IN PROGRESS GAME BOARD: ---+---+--- X | | X ---+---+--- | O | O ---+---+--- O | | X ---+---+--- Board Markings: XXXBOOOBX GAME STATUS: WINNER IS X GAME BOARD: ---+---+--- X | X | X ---+---+--- | O | O ---+---+--- O | | X ---+---+--- Board Markings: XXOOOXXOX GAME STATUS: DRAW GAME BOARD: ---+---+--- X | X | O ---+---+--- O | O | X ---+---+--- X | O | X ---+---+---
