三子棋的实现

Posted 2021-07-18 正义的伙伴啊

三子棋的游戏规则：

是黑白棋的一种。三子棋是一种民间传统游戏，又叫九宫棋、圈圈叉叉、一条龙、井字棋等。将正方形对角线连起来，相对两边依次摆上三个双方棋子，只要将自己的三个棋子走成一条线，对方就算输了。但是，有很多时候会出现和棋的情况。

实现三子棋我们还是分为三个文件：test.c game.c game.h 来实现函数

我直接就放代码了，思路和扫雷差不多：
test.c

#define _CRT_SECURE_NO_WARNINGS 1
#include<stdio.h>
#include"game.h"
#include<stdlib.h>
#include<time.h>
void game()
{
	char board[ROW][COL];
	initboard(board, COL, ROW);
	displayboard(board, COL, ROW);
	while (1)
	{
		char ret;
		playermove(board, COL, ROW);
		displayboard(board, COL, ROW);
		ret = check(board, COL, ROW);
		if (ret == '*')
		{
			printf("玩家获胜！！");
			break;
		}
		else if (ret == '#')
		{
			printf("电脑获胜！！！");
			break;
		}
		else if (ret == 'p')
		{
			printf("平局！！！");
			break;
		}

		computermove(board, COL, ROW);
		displayboard(board, COL, ROW);
		ret = check(board, COL, ROW);
		if (ret == '*')
		{
			printf("玩家获胜！！");
			break;
		}
		else if (ret == '#')
		{
			printf("电脑获胜！！！");
			break;
		}
		else if (ret == 'p')
		{
			printf("平局！！！");
			break;
		}
	}

}
void manu()
{
	printf("**********************************\\n");
	printf("***********1. play     ***********\\n");
	printf("***********2. exite    ***********\\n");
	printf("**********************************\\n");
	printf("**********************************\\n");
}
int main()
{
	srand((unsigned int)time(NULL));
	do
	{
		int n;
		manu();
		scanf("%d", &n);
		if (1 == n)
		{
			game();
		}
		else
			break;
	} while (1);
}

game.h

#pragma once
#define COL 3
#define ROW 3

void initboard(char board[][COL], int col, int row);                      //将棋盘初始化


void displayboard(char board[][COL], int col, int row);                   // 打印棋盘

void playermove(char board[][COL], int col, int row);                     //玩家移动

void computermove(char board[][COL], int col, int row);                    //电脑移动

char check(char board[][COL], int col, int row);

int isfull(char board[][COL], int col, int row);
//判断输赢： 1 玩家赢
//           2 电脑赢 
//           3 平局
//           4 以上都没有发生继续游戏，
