C++ Tic-Tac-Toe (2 parts)

Write a program that allows two players (player X and player O) to play a game of tic-tac-toe. Use

a two- dimensional char array with three rows and three columns as the game board.

Each element of the array should be initialized with an asterisk (*). The players take turns

making moves and the program keeps track of whose turn it is. Player X moves first.

The program should run a loop that:

Displays the contents of the board array (see prompts and output , below).

Prompts and allows the player whose turn it is to select a location on the board for an X in

the case of player X or an O in the case of player O. The program should ask the player to

enter the row and column number. Valid row or column numbers are 1, 2, or 3.

The loop terminates when 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 X (O) wins when there are three Xs (three Os) in a row on the game board. The Xs (Os) 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.

Input Validation: The program should check the validity of the row and column numbers entered

by the players. To be valid, the row and column number must refer to an unoccupied position in

the game board. When an invalid entry is made, the program simply redisplays its most recent

prompt and attempts to reread the value .

Prompts And Output Labels: The board is displayed as a sequence of three rows, each with

three characters . The characters are "X" or "O" or "." depending on whether player X or player O

has chosen that position or whether the position is still unselected. Thus the following:

. . X

O . X

. . .

represents the board when it's O's turn and when X has moved twice (to row1/column3 and

row2/column3) and O has moved once (to row2/column1).

Players are prompted as "Player X, row and column:" or "Player O, row and column:". The game's

end is announced either by "Player X wins", or "Player O wins" or "The cat wins" (in the case of

no winner).

Extend the feature of your Tic-Tac-Toe program to have the computer play against the user.

The computer will always start as the first move. The computer should never lose the game, no matter

what the user enters. So the computer can win or draw the game.
