【C语言】实现一个好玩的三子棋

想要用C语言写一个简单的三子棋游戏，首先要打印出三字棋的布局，对棋盘进行初始化；

在玩游戏时，玩家和电脑进行对完，因此要设计玩家和电脑两部分；

电脑和玩家下完一个棋之后，则要进行判断棋盘是否满，以及玩家和电脑哪一边赢。

首先是头文件

game.h:

#pragma once
    #define _CRT_SECURE_NO_WARNINGS 1
    #include<stdio.h>
    #include<stdlib.h>
    #include<time.h>
    #define rows 3
    #define cols 3
    
    int print_chessboard(char chessboard[rows][cols]);//打印棋盘
    int init(char chessboard[rows][cols]);// 初始化棋盘
    int menu();//菜单函数
    int ManPlay(char chessboard[rows][cols]);//玩家玩
    void CalPlay(char chessboard[rows][cols]);//电脑玩
    int chess_full(char chessboard[rows][cols]);//判断棋盘是否满 
    int Judge(char chessboard[rows][cols]);//判断输赢
    void Game(char chessboard[rows][cols]);//游戏

接下来是函数的实现，这一部分重要的是判断棋盘是否满和判断玩家和电脑哪一方赢

在电脑玩的时候要用到随机数产生1--3之间的随机数

game.c

#include"game.h"
    int count = 9;
    
    
    //打印棋盘
    int print_chessboard(char chessboard[rows][cols])
    {
    	int i = 0;
    	for (i = 0; i < rows - 1; i++)
    	{
    		printf(" %c | %c | %c \n", chessboard[i][0], chessboard[i][1], chessboard[i][2]);
    		printf("___|___|___\n");
    	}
    	printf(" %c | %c | %c \n", chessboard[2][0], chessboard[2][1], chessboard[2][2]);
    	printf("   |   |  \n");
    	return 0;
    }
    
    
    //初始化棋盘
    int init(char chessboard[rows][cols])
    {
    	int i = 0;
    	int j = 0;
    	for (i = 0; i < rows; i++)
    	{
    		for (j = 0; j < cols; j++)
    		{
    			chessboard[i][j] = ' ';
    		}
    	}
    	return 0;
    }
    
    //菜单函数
    int menu()
    {
    	printf("********************************************\n");
    	printf("********************************************\n");
    	printf("*************welcome to sanziqi*************\n");
    	printf("*************   1.      play   *************\n");
    	printf("*************   0.      exit   *************\n");
    	printf("********************************************\n");
    	printf("********************************************\n");
    	return 0;
    }
    
    //玩家玩
    int ManPlay(char chessboard[rows][cols])
    {
    	int x = 0, y = 0;
    	int ret = 0;
    	printf("请输入坐标：\n");
    	scanf("%d%d", &x, &y);
    	if (x<1 || x>3 || y<1 || y>3 || chessboard[x - 1][y - 1] != ' ')
    	{
    		printf("此处不能下棋！\n");
    		ManPlay(chessboard);
    	}
    	else
    	{
    		chessboard[x - 1][y - 1] = 'X';
    		count--;
    	}
    	return 0;
    }
    
    
    //电脑玩
    void CalPlay(char chessboard[rows][cols])
    {
    	printf("电脑下棋：\n");
    	int x = 0;
    	int y = 0;
    	srand((unsigned)time(NULL));
    	x = rand() % 3;
    	y = rand() % 3;
    	while (chessboard[x][y] != ' ')
    	{
    		x = rand() % 3;
    		y = rand() % 3;
    	}
    	chessboard[x][y] = 'O';
    	count--;
    }
    
    //判断棋盘是否满 
    int chess_full(char chessboard[rows][cols])
    {
    	if (count == 0)
    		return 1;
    	return 0;
    }
    
    //判断输赢
    int Judge(char chessboard[rows][cols])
    {
    	int ret = 2;
    	int i = 0;
    	if ((chessboard[0][0] == chessboard[1][1]) && (chessboard[1][1] == chessboard[2][2]))
    	{
    		if (chessboard[1][1] == 'X')
    		{
    			ret = 1;
    		}
    		if (chessboard[1][1] == 'O')
    		{
    			ret = 0;
    		}
    	}
    	if ((chessboard[0][2] == chessboard[1][1]) && (chessboard[1][1] == chessboard[2][0]))
    	{
    		if (chessboard[1][1] == 'X')
    		{
    			ret = 1;
    		}
    		if (chessboard[1][1] == 'O')
    		{
    			ret = 0;
    		}
    	}
    	for (i = 0; i < rows; i++)
    	{
    		if ((chessboard[i][0] == chessboard[i][1]) && (chessboard[i][1] == chessboard[i][2]))
    		{
    			if (chessboard[i][1] == 'X')
    			{
    				ret = 1;
    			}
    			if (chessboard[i][1] == 'O')
    			{
    				ret = 0;
    			}
    		}
    	}
    
    	for (i = 0; i < rows; i++)
    	{
    		if ((chessboard[0][i] == chessboard[1][i]) && (chessboard[1][i] == chessboard[2][i]))
    		{
    			if (chessboard[1][i] == 'X')
    			{
    				ret = 1;
    			}
    			if (chessboard[1][i] == 'O')
    			{
    				ret = 0;
    			}
    		}
    	}
    	return ret;
    }
    
    //游戏
    void Game(char chessboard[rows][cols])
    {
    	int i = 0;
    	int ret = 0;
    	//	char chessboard[rows][cols];
    	init(chessboard);
    	print_chessboard(chessboard);
    	while ((chess_full(chessboard) == 0))
    	{
    		ManPlay(chessboard);
    		ret = Judge(chessboard);
    		if (ret == 1)
    		{
    			printf("玩家赢了!\n");
    			break;
    		}
    		else if (ret == 0)
    		{
    			printf("电脑赢了!\n");
    			break;
    		}
    		CalPlay(chessboard);
    		print_chessboard(chessboard);
    		ret = Judge(chessboard);
    		if (ret == 1)
    		{
    			printf("玩家赢了!\n");
    			break;
    		}
    		else if (ret == 0)
    		{
    			printf("电脑赢了!\n");
    			break;
    		}
    	}
    }

最后是测试函数:

text.c

#include"game.h"
    
    int main()
    {
    	int input = 0;
    	char chessboard[rows][cols];
    	menu();
    	while (1)
    	{
    		printf("请选择:");
    		scanf("%d", &input);
    		if (input == 1)
    		{
    			printf("进入游戏\n");
    			Game(chessboard);
    			break;
    		}
    		else if (input == 0)
    		{
    			printf("退出游戏！\n");
    			exit(0);
    			break;
    		}
    		else
    		{
    			printf("输入有误！\n");
    		}
    	}
    	return 0;
    }

下来我们就可以玩三子棋了
