Question

Write a program that allows two players to play a game of tic-tac-toe. Use a twodimensional char array with three rows and three columns as the game board. Each element in the array should be initialized with an asterisk (*). 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. At game end, show the menu to Play the Game, Display the Game Stats, or Quit. 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. Player 2 wins with the same conditions. A tie occurs when all of the locations on the board are full, but there is no winner.

• The user is allowed to play the game multiple times. Use a menu to allow the player to choose to Play the Game, Display the Game Stats, or Quit. • Track game stats as follows - total number of games played, how many times Player 1 wins, how many times Player 2 wins, and how many tie games.

utilize a 2D array for the gameboard, and to utilize structs, functions, parameters, loops, branching and good design.

do not use pointers
