Add the additional functionality described

below:

This week you will create a game board array that will save player moves. Start by

declaring this array as a 2D-array of integers with size BOARD_SIZE (at this time make

sure BOARD_SIZE is equal to 8). Create a set of macros that will define whether a space

on the game board is an EMPTY_SPACE, P1_SPACE, or P2_SPACE. An example of the

#define directives is as follows:

//Board Size Constant

#define BOARD_SIZE 8

//Board Space Constants

#define EMPTY_SPACE 0

#define P1_SPACE 1

#define P2_SPACE 2

//Player Constants

#define PLAYER1 1

#define PLAYER2 2

You will use these macros as values in your game board array. Set every cell in the game

board array to EMPTY_SPACE. Then set indices [3][3] and [4][4] to P1_SPACE and indices

[3][4] and [4][3] to P2_SPACE.

Now modify your printBoard function to take the game board array as the only

parameter. Modify the function to print out 'B' (for P1_SPACE), 'W' (for P2_SPACE), and

'.' (for EMPTY_SPACE) using your macros defined earlier. Finally, modify the code in your

program where you call the printBoard function to now take the 2D game board array as a

parameter.

Next, you may delete the code in your game loop that asks for a second coordinate, as

well as the print statements that print the alignment of the coordinates. You will only be

asking for one coordinate from now on (See sample output for example).

Finally create a function called playMove, which takes the x and y coordinates, the

current player’s turn variable, and the 2D game board array as parameters and returns an

integer. The function should set the board space at index [x][y] to the appropriate space

macro defined from earlier (P1_SPACE or P2_SPACE) depending on the player variable

passed in. This function should return 1 for now. We will modify this function more in the

coming weeks (as of right now, players will be able to overwrite previous moves. We will

change this later).

The prototypes of the functions are as follows:

int getAlignment(int, int, int, int);//Returns Alignment Constant

void printBoard(int[BOARD_SIZE][BOARD_SIZE])//Prints Game Board

int validateInput();

int playMove(int, int, int, int [BOARD_SIZE][BOARD_SIZE]);

The output has been given below.....

Sample output: Enter Player 1's First Name: John Enter Player 1's Last Name: Smith Enter Player 2's First Name: Jill Enter Player 2's Last Name: Tucker 1 2 3 4 5 6 7 8 BW W B John Smith's Score (B): 2.0 Jill Tucker's Score (W): 2.0 John Smith, it is your turn Enter X coordinate -1 Invalid Input Enter again 9 Invalid Input Enter again 0 Invalid Input Enter again 1 Enter Y coordinate: 3 1 2 3 4 5 6 7 8 3 B BW W B Enter an integer to continue (q to exit): 10 John Smith's Score (B): 2.0 Jill Tucker's Score (W) 2.0 Jill Tucker, it is your turn Enter X coordinate: 4.5 Enter Y coordinate: 2 1 2 3 4 5 6 7 8 3 B BW W B Enter an integer to continue (q to exit): q
