用C语言实现三子棋游戏

1.头文件部分
#ifndef _THREE_CHESSH
#define _THREE_CHESSH

#include<stdio.h>
#include<windows.h>
#include<string.h>
#include<time.h>
#pragma warning(disable:4996)

#define ROW 3
#define COL 3

void ShowUI();
void Game();
void ComputerMove(char board[ROW][COL], int row, int col);
void PlayerMove(char board[][COL], int row, int col);
void ShowBoard(char board[][COL], int row, int col);
char Judge(char board[][COL], int row, int col);

#endif

2.主函数部分
#include"Three_Chess.h"

int main()
{
int select = 0;
int quit = 0;
while (!quit)
{
ShowUI(); //打印游戏菜单
scanf("%d", &select); //用户进行选择
