三子棋小游戏的实现

初次写这个小游戏，程序设计也比较简单，其中还有许多需要改进的地方。
这个三子棋程序我同样使用了三个文件，game.h、game.c、和test.c
game.h
#define _CRT_SECURE_NO_WARNINGS 1

#define ROWS 3//行数
#define COLS 3//列数

void InitBoard(char board[ROWS][COLS], int row, int col);//棋盘初始化
void Display_board(char board[ROWS][COLS], int row, int col);//打印棋盘
void Player_Move(char board[ROWS][COLS], int row, int col);//玩家走
void Computer_Move(char board[ROWS][COLS], int row, int col);//电脑走
char Is_Win(char board[ROWS][COLS], int row, int col);//判断输赢
#endif//__GAME_H__game.c
#include"game.h"

{
memset(board, ' ', row*col*sizeof(board[0][0]));

scanf("%d%d", &x, &y);
