一.问题描述

用c语言实现三子棋游戏

二.基本流程及步骤

写三子棋游戏前的逻辑构建

步骤

1.菜单界面

开始游戏1，退出游戏0

void menu()
{
	printf("**** 三子棋游戏 **\n");
	printf("****** 1.play ****\n");
	printf("****** 0.eixt ****\n");
	printf("******************\n");
}

2.创建棋盘

使用二维数组3x3矩阵

#define ROW 3
#define COL 3

char ret = 0;
char board[ROW][COL] = { 0 };

3.棋盘初始化

//初始化棋盘功能实现
void InitBoard(char board[ROW][COL], int row, int col)
{
	int i, j;
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col; j++)
		{
			board[i][j] = ' ';
		}
	}

4.打印棋盘

//打印棋盘功能的实现
void DisplayBoard(char board[ROW][COL], int row, int col)
{
	int i = 0;
	//int j = 0;
	for (i = 0; i < row; i++)
	{
		//打印数据
		int j = 0;
		for (j = 0; j < col; j++)
		{
			printf(" %c ", board[i][j]);
			if (j < col - 1)
				printf("|");
		}
		printf("\n");
		//打印分割信息
		if (i < row - 1)
		{
			int j = 0;
			for (j = 0; j < col; j++)
			{
				printf("___");
				if (j < col - 1  )
					printf("|");
			}
			printf("\n");
		}
	}
	printf("\n");
}

5.玩家下棋

玩家下棋需要在棋盘范围内

玩家需要在棋盘上的口地方下棋

如果输入坐标非法需要重新输入

//玩家下棋功能的实现
void PlayMove(char board[ROW][COL], int row, int col)
{
	printf("玩家下棋:\n");
	int x = 0;
	int y = 0;
	int flag = 1;
	while (flag)
	{
		printf("请输入下棋的位置:>");
		scanf_s("%d%d", &x, &y);
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
			if (board[x - 1][y - 1] == ' ')
			{
				board[x - 1][y - 1] = 'O';
				break;
			}
			else
			{
				printf("坐标已被占用，请重新选择位置!\n");
			}
		}
		else
		{
			printf("输入的坐标非法，请重新输入!\n");
		}
	}
}

6电脑下棋

电脑下棋需要调用随机数srand((unsigned int)time(NULL));//设置随机数的位置

游戏规则与玩家下棋同理

//电脑下棋功能的实现
void ComputerMove(char board[ROW][COL], int row, int col)
{
	printf("电脑下棋:\n");
	int x = 0;
	int y = 0;
	int flag = 1;
	while (flag)
	{
		x = rand() % row;
		y = rand() % col;
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
			if (board[x][y] == ' ')
			{
				board[x][y] = 'X';
				break;
			}
			else
			{
				printf("坐标已被占用，请重新选择坐标位置!\n");
			}
			//printf("\n");
		}
		else
		{
			printf("坐标非法,请重新输入!\n");
		}
		//printf("\n");
	}
}

7.判断输赢

其中判断棋盘是否下满需要调用到IsFull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;
}

//判断输赢功能的实现
char IsWin(char board[ROW][COL], int row, int col)
{
	int i = 0;
	//判断行
	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];
		}
	}
	//判断列
	for (i = 0; i < col; i++)
	{
		if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ')
		{
			return board[1][i];
		}
	}
	//判断对角线
	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
	//棋盘满了返回1，棋盘未满返回0
	int ret = IsFull(board, row, col);
	if (ret == 1)
	{
		return 'Q';
	}
	//继续
		return 'C';
}

三.代码实现

test.c

#define _CRT_SECURE_NO_WARNIGNS 1
#include "game.h"

void menu()
{
	printf("**** 三子棋游戏 **\n");
	printf("****** 1.play ****\n");
	printf("****** 0.eixt ****\n");
	printf("******************\n");
}
void game()
{
	char ret = 0;
	char board[ROW][COL] = { 0 };
	//初始化棋盘
	InitBoard(board, ROW, COL);
	//打印棋牌
	DisplayBoard(board, ROW, COL);
	int flag = 1;
	while (flag)
	{
		PlayMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		//判断输赢
		ret = IsWin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
		
		ComputerMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		ret = IsWin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
		
	}
	if (ret == 'O')
	{
		printf("玩家赢!\n");
	}
	else if (ret == 'X')
	{
		printf("电脑赢!\n");
	}
	else
	{
		printf("平局!\n");
	}
	DisplayBoard(board, ROW, COL);
}
void test()
{
	srand((unsigned int)time(NULL));//设置随机数的位置
	int input = 0;
	do
	{
		menu();//打印游戏菜单
		printf("输入选择的数字:>");
		scanf_s("%d", &input);
		switch (input)
		{
		case 1:
			printf("开始游戏:\n");
			game();
			break;
		case 0:
			printf("退出游戏!\n");
			break;
		default:
			printf("选择错误!\n");
			break;
		}
	} while (input);
}
int main(void)
{
	test();
	return 0;
}
