Write a program that implements the game of Tic-Tac-Toe where you can play against the computer. Player 1 will be the user and player 2 will be the computer. Your program should go through the following steps:

1.Generate an empty Tic-Tac-Toe board (3x3 array)

2.Run a loop until one of the players places three in a row (a player has won) or the table is full (stalemate).

This loop should:

a.Display the current layout of the table

i.Blank spaces are displayed as an underscore

ii.O for player 1s moves (user)

iii.X for player 2s moves (computer)

iv.Put spaces between the squares

b.If it is player 1s turn (the user)

i.Ask the user to enter their selection (the location on the board where the O should be placed (row, col))

ii.Check to make sure that the row and column the user entered is valid

iii.If the row or column player 1 entered was invalid (outside the bounds of the board or a space that is already occupied) the program should ask the user to enter the option again.

c. If it is player 2s turn (the computer)

i. Randomly generate a move (row, col) in the board that is not currently occupied (if the

computer selects and occupied space generate a new move)

ii.To generate a random move: generate two random integers, one for the row and one for

the column, each between 0 and 2

iii.Print out player 2s move

iv.Update the board with player 2s move

3.If the above loop ends because one of the players has placed three in a row then the program should print

out a winning message of that player (see below). Else, it should print out the follow:

Game over, no player wins.

The program should function as follows (items underlined are to be entered by the user):

The current state of the game is:

_ _ _

_ _ _

_ _ _

Player 1 enter your selection [row, col]: 1,2

The current state of the game is:

_ O _

_ _ _

_ _ _

Player 2 has entered [row, col]: 1,3

The current state of the game is:

_ O X

_ _ _

_ _ _

Player 1 enter your selection [row, col]: 2,2

The current state of the game is:

_ O X

_ O _

_ _ _

Player 2 has entered [row, col]: 2,1

The current state of the game is:

_ O X

X O _

_ _ _

Player 1 enter your selection [row, col]: 3,2

The current state of the game is:

_ O X

X O _

_ O _

Congratulations, Player 1 wins!

Your program should implement and use the following functions:

?The board as a 3x3 array

Requirements:

?Prints out the following message:

The current state of the game is:

?Prints out the current status of the board (as shown above)

Print out an underscore _ for an empty cell

?Function name: clear_table

Return:

?Nothing

Parameters:

?The board as a 3x3 array

Return:

?Nothing

Parameters:

?The board as a 3x3 array

?The move (row and column)

Requirements:

?If the game is not over:

-Print out the generated move (as seen above)

-Print out the current state of the board

? Function name: check_three_in_a_row

Return:

? Zero if no one has three in a row

? One if player 1 has three in a row

? Two if player 2 has three in a row

Parameters:

?The board as a 3x3 array

Requirements:

?Returns the ID of the player that has three in a row or zero if no one has three in a row

?Function name: check_end_of_game

Return:

?True if the game has ended

?False if the game hasnt ended

Parameters:

?The board as a 3x3 array

?Returns true or false depending on if the game is over or not

?Function name: get_player1_move

Return:

? Nothing

Parameters:

? The board as a 3x3 array

? The move (row and column)

Requirements:

? If the game is not over:

-Get a possible move from the user (as seen above)

-If the given move is not valid get another move from the user until you have a valid move

-Update the board with the given, valid move

-Print out the current state of the board

? Function name: print_winner

Return:

?Nothing

Parameters:

?The board as 3x3 array

Requirements:

? If a player has won prints out the victory message (as seen above)

? If the game is a stalemate prints:

-Game over, no player wins.

This is the main function. Copy this into your code and write the ten functions from above in order to make the

program work.

int main ()

{

//Declare the tic-tac-toe board

char board[SIZE][SIZE];

//The row and column of the move for either player 1 or 2

int row, col;

//Clear the table

clear_table(board);

//Display the table

display_table(board);

do

{

//Have player 1 enter their move

get_player1_move(board, row, col);

//Generate player 2 move

generate_player2_move(board, row, col);

//Do this while the game hasn't ended

}while(check_end_of_game(board) == false);

//After the game is over, print who won

print_winner(board);

return 0;

}

Notes:

?You are NOT allowed to use global variables

?You cannot add parameters to any function

?SIZE is defined as 3 using a #define at the top of the program
