【三子棋游戏】———C语言实现

void menu()
{
	printf("**********************************\n");
	printf("***** 1.开始游戏  0.退出游戏 *****\n");
	printf("**********************************\n");
}

void game()
{
	char ret = 0;
	char board[ROW][COL] = { 0 };
	//初始化棋盘
	InitBoard(board,ROW,COL);
	//打印棋盘
	DisplayBoard(board, ROW, COL);

	while (1)
	{
		//玩家走棋
		PlayerMove(board, ROW, COL);
		ret = IsWin(board, ROW, COL);
		if (ret != 'g')
		{
			break;
		}
		DisplayBoard(board, ROW, COL);
		//电脑走棋
		ComputerMove(board, ROW, COL);
		ret = IsWin(board, ROW, COL);
		if (ret != 'g')
		{
			break;
		}
		DisplayBoard(board, ROW, COL);
	}
	if (ret == '*')
	{
		printf("玩家赢了！！！\n");
	}
	else if (ret == '#')
	{
		printf("电脑赢了！！！\n");
	}
	else
	{
		printf("平局！！！\n");
	}
	DisplayBoard(board, ROW, COL);
}

int main()
{
	srand((unsigned int)time(NULL));
	int input = 0;
	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("输入有误，请重新选择\n");
			break;
		}
	} 
	while (input);
}

2.初始化棋盘

//初始化棋盘
void InitBoard(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++)
		{
			board[i][j] = ' ';
		}
	}
}

3.打印棋盘

//打印棋盘
void DisplayBoard(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)
		{
			int j = 0;
			for (j = 0; j < col; j++)
			{
				printf("---");
				if (j < col - 1)
				{
					printf("|");
				}
			}
		}
		printf("\n");
	}
}

4.玩家走棋

//玩家走棋
void PlayerMove(char board[ROW][COL], int row, int col)
{
	while (1)
	{
		int x = 0;
		int y = 0;
		printf("玩家走棋:->");
		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("此坐标已经被占用，请重新输入\n");
			}
		}
		else
		{
			printf("坐标非法，请重新输入\n");
		}
	}
}

5.电脑走棋

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

6.判断输赢

//判断输赢
//玩家赢- *
//电脑赢-#
//平局-e
//继续-g

//判断是否满盘
int IsFull(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++)
		{
			if (board[i][j] == ' ')
			{
				return 0;
			}
		}
	}
	return 1;
}

char IsWin(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][1] != ' ')
		{
			return board[i][1];
		}
	}

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

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

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

	if (IsFull(board, ROW, COL))
	{
		return 'e';
	}
	else
	{
		return 'g';
	}
}

7.细节

函数声明放在game.h文件中

函数定义以及游戏代码实现放在game.c文件中

#include<stdio.h>

#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);

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

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

//判断输赢
char IsWin(char board[ROW][COL], int row, int col);

//判断是否满盘
int IsFull(char board[ROW][COL], int row, int col);

全局定义行和列数，方便后期可以随时增加行和列
