三子棋

三子棋游戲
一、分析

1.創建一個進入游戲讓玩家選擇的框架
2.創建一個三子棋的棋盤，棋盤內部存放玩家和電腦下的棋子，所以總的來說棋盤是由一個二維數組和棋盤框架構成的
3.對棋盤進行操作
4.判斷棋局並做出調整

二、代碼

game.h

#define _CRT_SECURE_NO_WARNINGS 1
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <time.h>

#define ROW 3
#define COL 3

//初始化數組
void Init(char board[ROW][COL], int row, int col);
//列印棋盤
void Display(char board[ROW][COL], int row, int col);
//玩家下棋
void PlayerMove(char board[ROW][COL], int row, int col);
//電腦下棋
void ComputerMove(char board[ROW][COL], int row, int col);
//判斷輸贏
char Is_Win(char board[ROW][COL], int row, int col);
