17. Tic-Tac-Toe Game
Write a program that allows two players to play a game of tic-tac-toe. Use a twovdimensional
char array with three rows and three columns as the game board. Each
element of the array should be initialized with an asterisk (':0). The program should run a
loop that
• Displays the contents of the board array
• Allows player 1 to select a location on the board for an X. The program should
ask the user to enter the row and column number.
• Allows player 2 to select a location on the board for an O. The program should
ask the user to enter the row and column number.
• Determines whether a player has won, or a tie has occurred. If a player has won,
the program should declare that player the winner and end. If a tie has occurred,
the program should say so and end.

Player 1 wins when there are three Xs in a row on the game board. The Xs can appear
in a row, in a column, or diagonally across the board. A tie occurs when all of the
locations on the board are full, but there is no winner.

Explanation / Answer

please rate - thanks

coordinates are 1-3 and entered separated by a comma.

top left hand corner you would enter as 1,1
