I have a .C program that can play TicTacToe (human vs computer) the program is working , what I need help is with adding a do/while loop to the program or some kind of function that ask the player if it wanna play again? yes or no, if yes repeat the game if no terminate the program.

Full Code, please modify to adjust or leave steps to fallow: #include #include #define _CRT_SECURE_NO_WARNINGS
