前言

想必大家都玩过三子棋吧，

三子棋又叫九宫棋、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。

今天Menon-chao就带你们一起用C语言来编写一个简单的三子棋小游戏吧。

一、首先，我们需要创建新的项目，分别有以下三个空项目：

1.game1.c

用来测试三子棋游戏

2.game2.c

用来实现三子棋函数

3.game.h

三子棋的函数声明

二、三子棋游戏的代码实现

1.简单菜单的创建：

void menu()
{
	printf("*****************************\n");
	printf("*********   1.play   ********\n");
	printf("*********   0.exit   ********\n");
	printf("*****************************\n");
}

完成后的菜单展示：

 2.棋盘的初始化及棋盘的打印：

void init_board(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (i = 0;i < row;i++)
	{
		for (j = 0;j < col;j++)
		{
			board[i][j] = ' ';
		}
	}
}

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

}

 棋盘初始化和打印后的棋盘：

 3.玩家下棋的实现：

void player_move(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	printf("玩家下棋:\n");
	while (1)
	{
		printf("请输入要下的坐标:");
		scanf("%d %d", &x, &y);
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
			if (board[x - 1][y - 1]== ' ')
			{
				board[x - 1][y - 1]= '*';
				break;
			}
			else
			{
				printf("该坐标被占用，请重新输入\n");
			}
		}
		else
		{
			printf("坐标非法，重新输入\n");
		}
	}

	
}

4.电脑下棋的实现：

void computer_move(char board[ROW][COL], int row, int col)
{
	printf("电脑下棋:\n");
	while (1)
	{
		int x = rand() % row;
		int y = rand() % col;
		if (board[x][y]==' ')
		{
			board[x][y]='#';
			break;


		}
	}
		
}

电脑下棋：

5.游戏状态的判断：

char is_win(char board[ROW][COL], int row, int col)
{
	int i = 0;
	for (i = 0; i < row; i++)
	{
		if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][0] != ' ')
		{
			return board[i][0];
		}
	}

	for (i = 0; i < col; i++)
	{
		if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] != ' ')
		{
			return board[0][i];
		}
	}

	if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ')
	{
		return board[1][1];
	}

	if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
	{
		return board[1][1];
	}

以上为三子棋游戏的主要代码和思路。

三、总代码：

game.h:

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


#define ROW 3
#define COL 3

//初始化棋盘
void init_board(char board[ROW][COL], int row, int col);

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

//玩家下棋
void player_move(char board[ROW][COL], int row, int col);

//电脑下棋
void computer_move(char board[ROW][COL], int row, int col);


//判断游戏状态
char is_win(char board[ROW][COL], int row, int col);

//电脑随机下棋
void computer_move(char board[ROW][COL], int row, int col)
{
	printf("电脑下棋:\n");
	while (1)
	{
		int x = rand() % row;

//如果棋盘满了，返回1

static int is_full(char board[ROW][COL], int row, int col)
