C语言小游戏：三字棋

    根据最近一段时间的学习，对C语言也有了一些入门，进而进而编写了一个用C语言实现的小游戏：三字棋。
    这个程序的大致思路为，先打印一个3*3的棋盘来展示，然后考虑到两方对下，放置于3*3的棋盘当中去，进而想到用一个二维数组来实现。然后进行编程。然后就是人机之间的相互轮转下棋。程序如下：

#ifndef __GAME_H__
#define __GAME_H__

#include <stdlib.h>
#include <stdio.h>
#include <time.h>
#include <windows.h>

#define ROW 3
#define COL 3

void InitBoard(char board[ROW][COL], int row, int col);
void Printf_Board(char board[ROW][COL], int row, int col);
void PlayerMove(char board[ROW][COL], int row, int col);
void RobotMove(char board[ROW][COL], int row, int col);
char CheckWin(char board[ROW][COL], int row, int col);

#endif      //__GAME_H__

#include "game.h"

void Printf_Board(char board[ROW][COL], int row, int col)

    {
        for (j = 0; j < col; j++)
        {
            printf(" %c ",board[i][j]);
            if (j < col - 1)
                printf("|");
        }
        printf("\n");
        if (i < row - 1)
            printf("---|---|---\n");
    }
    printf("\n");
}

{
    int i = 0;
    int j = 0;
    for (i = 0; i < row; i++)
    {
        for (j = 0; j < col; j++)
        {
            board[i][j] = ' ';
        }
    }
}

void PlayerMove(char board[ROW][COL], int row, int col)
{
    int x = 0;
    int y = 0;
    printf("玩家走\n");
    while (1)
    {
        printf("请输入坐标:>");
        scanf("%d%d", &x, &y);

            break;
