一、问题描述
用C语言实现三子棋

二、基本步骤
1.添加game.c和test.c源文件，game.h头文件
2.创建菜单，玩家选择开始游戏或退出游戏
3.初始化棋盘
4.打印出棋盘
5.玩家下棋
6.电脑下棋
7.判断胜负

三、主要函数
1.菜单界面

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

2.初始化棋盘

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

3.打印棋盘

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

4.玩家下棋

void PlayerMove(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	while(1)
	{ 
		printf("请输入坐标:<");
		scanf("%d,%d", &x, &y);
		if (x <= row && y <= col && board[x - 1][y - 1] == ' ')
		{
			board[x - 1][y - 1] = '*';
			break;
		}
		else
		{
			printf("输入坐标非法，请重新输入");
		}
	}

}

5.电脑下棋

void ComputerMove(char board[ROW][COL], int row, int col)
{
	while(1)
	{
		int x = rand() % row;
		int y = rand() % col;
		if (board[x][y] == ' ')
		{
			board[x][y] = '#';
			break;
		}
	}
}

6.判断平局

int Is_full(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 1;
		}
	}
	return 0;
}

7.判断胜负

int Is_win(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	//判断行
	for (i = 0;i < row; i++)
	{
		if (board[i][0] == '*' && board[i][1] == '*' && board[i][2] == '*')
		{
			return 1;
		}
		else if (board[i][0] == '#' && board[i][1] == '#' && board[i][2] == '#')
		{
			return 0;
		}
	}
	//判断列
	for (i = 0;i < row; i++)
	{
		if (board[0][i] == '*' && board[1][i] == '*' && board[2][i] == '*')
		{
			return 1;
		}
		else if (board[0][i] == '#' && board[1][i] == '#' && board[2][i] == '#')
		{
			return 0;
		}
	}
	//判断对角线
	if ((board[0][0] == '*' && board[1][1] == '*' && board[2][2] == '*')
		|| (board[0][2] == '*' && board[1][1] == '*' && board[2][0] == '*'))
	{
		return 1;
	}
	else if ((board[0][0] == '#' && board[1][1] == '#' && board[2][2] == '#')
		|| (board[0][2] == '#' && board[1][1] == '#' && board[2][0] == '#'))
	{
		return 0;
	}
	//判断是否平局
	int ret = Is_full(board, row, col);
	if (ret == 0)
	{
		return 2;
	}

	return 3;
}

int main()
{
	srand((unsigned int)time(NULL));
	int input = 0;
	do

		menu();
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			game();
			break;
		case 0:
			break;
		default:

}

1.使用宏定义:提高代码可读性，也便于修改

#define ROW 3
#define COL 3

2.电脑随机生成落子坐标在主函数中使用

srand((unsigned int)time(NULL));
