C语言实现三子棋

实现三子棋的思路

创建游戏的初始化界面

创建一个名为board的二维数组并且初始化

将棋盘进行搭建并且打印出来

玩家进行下棋并且打印

电脑下棋并且打印

判断结果

还需要注意的是，我们创建游戏的过程中需要用到两个源文件（game.c test.c）和一个头文件（game.h)，在头文件中包含了程序所需的各种头文件并且实现对各种函数的声明，而源文件test.c用于引用函数，game.c实现函数。这样做的目的是为了各个文件可以处理各自模块的功能，增强逻辑性和代码的清晰度，使得可读性更高。

实现游戏的初始。

代码语言：javascript复制

int main()
{
	int input = 0;
	srand((unsigned int)time(NULL));
	do
	{
		menu();
		printf("请选择：>");
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			game();
			break;
		case 0:
			printf("退出游戏n");
			break;
		default:
			printf("选择错误，请重新选择：n");
			break;
			
		}
	} while (input);
	return 0;
}

首先打印菜单让玩家选择，1进入游戏，0退出游戏。

代码语言：javascript复制

void menu()
{
	printf("#########################n");
	printf("#####   1.Play     ######n");
	printf("#####   0.Exit     ######n");
	printf("#########################n");
}

如果玩家进入游戏，则进入game（）。

代码语言：javascript复制

void game()
{
	char ret = 0;
	char board[ROW][COL];
	//打印棋盘
	InitBoard(board, ROW, COL);
	DisplayBoard(board, ROW, COL);
	//下棋
	while (1)
	{   
		//玩家下棋
		PlayerMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		//判断输赢
		ret = is_win(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
		//电脑下棋
		ComputerMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		ret = is_win(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
	}
	if (ret == '*')
	{
		printf("玩家赢n");
	}
	else if (ret == '#')
	{
		printf("电脑赢n");
	}
	else if (ret == 'Q')
	{
		printf("平局n");
	}
}

进入游戏后我们将棋盘进行搭建并打印让玩家看到。

代码语言：javascript复制

#define ROW 3
#define COL 3

//初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col);
//打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col);

void InitBoard(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 DisplayBoard(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i  )
	{
		//先打印数据
		for (j = 0; j < col; j  )
		{
			printf(" %c ", board[i][j]);
			if (j < col - 1)
				printf("|");
		}
		printf("n");
		//在打印分隔行
		if (i < row - 1)
		{
			for (j = 0; j < col; j  )
			{
				printf("---");
				if (j < col - 1)
					printf("|");
			}
		}
		printf("n");
	}
}

玩家下棋并打印棋盘

代码语言：javascript复制

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

//玩家下棋为*
//电脑下棋为#
void PlayerMove(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	printf("玩家下棋n");
	//开始下棋
	while (1)
	{
		printf("请输入要下棋的坐标:>");
		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，请重新输入坐标n");
			}
		}
		else
		{
			printf("坐标错误，请重新输入:n");
		}
	}
}

电脑下棋并打印，通过rand（）函数产生随机值，用%限制范围。

代码语言：javascript复制

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

//电脑下棋
void ComputerMove(char board[ROW][COL], int row, int col)
{
	printf("电脑下棋:n");
	int x = 0;
	int y = 0;
	while (1)
	{
		x = rand() % row;
		y = rand() % col;
		if (board[x][y] == ' ')
		{
			board[x][y] = '#';
			break;
		}
	}
}

判断结果，如果棋盘被占满则平局，创建IsFull函数判断棋盘是否被占满。

代码语言：javascript复制

//判断平局函数
int IsFull(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  )
		{
			if (board[i][j] == ' ')
				return 0;
		}
	}
	return 1;
}

//1.玩家赢-'*'
//2.电脑赢-'#'
//3.平局-'Q'
//4.继续--'C'
	
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];
	}
	//判断平局
	if (IsFull(board, row, col))
	{
		return 'Q';
	}
	return 'C';
}
