EXTRA CREDIT 1: Tic Tac Toe

(Please use c++ code) also please verify it works because I've received wrong answers in the past. Thank You

99 17 30 12 EXTRA CREDIT 1: Tic Tac Toe (10 points) Write a console program that plays Tic Tac Toe with the user. The program displays a 3 by 3 grid, which is initially blank. When the player takes a turn, an X is added to the grid. When the computer takes a turn, a O is added to the grid. After each turn, simply print out the grid. As a result, old states of the grid will scroll up in the console window. After each turn, your code needs to check for a win or a tie. If either of these conditions are met, then the program displays the result and terminates.

Answer: Hi, here I have given some code for play tic tac toe game with against either player 2 or computer. This is very simple and I have explained well below with screen shots of output through console form. Source code: # include #include #include ios <string> <stdlib.h> tream> using namespace std struct TicTacToe i char Board [3] [3]; char playerl; char p char com; void initalize board (char Board [3] [3]) for (int x = 0; x < 3; x++) { for (int y = 0, y 〈 3; y++) { Board [ x1Ly] = '.
