Gobang games

First, in the VC2013 Create project on , Create separate ：test.c、game.c、game.h Three sub files .

game.h：

#define ROW 3
#define COL 3
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

// Statement 
void InitBoard(char board[ROW][COL], int row, int col);
void DisplayBoard(char board[ROW][COL], int row, int col);
void PlayerMove(char board[ROW][COL], int row, int col);
void ComputerMove(char board[ROW][COL], int row, int col);
// Tell us the four states of the game : Game player wins 、 Computers win 、 It ends in a draw 、 Keep playing 
char IsWin(char board[ROW][COL], int row, int col);
int IsFull(char board[ROW][COL], int row, int col);
