三子棋游戏实现

        相信许多小伙伴都玩过三子棋游戏，而这里将编辑代码进行人机对弈。不过这里小编的技术还不太成熟所以‘机’还不算很智能，欢迎大家来讨论。

这里我将代码分为三个文件，分别为头文件代码符号的定义game.h；代码中函数的实现game.c;代码的主体test.c。   

1.选择是否进行游戏

代码语言：javascript复制

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

2.游戏实现

(1)输出棋盘

 输出一个3*3的棋盘

这里更改数字可以控制棋盘的大小。

代码语言：javascript复制

//初始化棋盘
void DisplayBord(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  )
		{
			printf(" %c ", board[i][j]);
			if (j < col - 1)
				printf("|");
		}
		printf("n");//换行
		if (i < row - 1)
		{
			for (j = 0; j < col; j  )
			{
				printf("---");
				if (j < col - 1)
					printf("|");
			}
		}
		printf("n");
	}
}

（2）玩家下棋

代码语言：javascript复制

void PlarerMove(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，请输入其他坐标n");
			}
		}
		else
		{
			printf("坐标非法，请重新输入n");
		}
	}
}

（3）电脑下棋

代码语言：javascript复制

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;
		}
	}
}

(4)判断输赢

代码语言：javascript复制

static 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;
}

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][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[0][0];
	}
	if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
	{
		return board[1][1];
	}
	if (IsFull(board, row, col))
	{
		return 'Q';
	}
	return 'C';
}

3.头文件gaem.h

代码语言：javascript复制

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

#define ROW 3
#define COL 3

//初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col);
//输出棋盘
void DisplayBord(char board[ROW][COL], int row, int col);
//玩家下棋·
void PlarerMove(char board[ROW][COL], int row, int col);
//电脑下棋（随机下
void ComputerMove(char board[ROW][COL], int row, int col);
//判断输赢
char IsWin(char board[ROW][COL], int row, int col);

4.主函数test.c

代码语言：javascript复制

#include "game.h"  //调用头文件
void menu()
{
	printf("**************************n");
	printf("******* 1.plsy  **********n");
	printf("******* 0.exit  **********n");
	printf("**************************n");
}

void game()
{
	char ret = 0;
	char board[ROW][COL];//board 背景，板 
	//开始的时候内容应该都是空格
	InitBoard(board, ROW, COL);
	DisplayBord(board, ROW, COL);
	//下棋
	while (1)
	{
		PlarerMove(board, ROW, COL);
		DisplayBord(board, ROW, COL);
		ret=IsWin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
		ComputerMove(board,ROW,COL);
		DisplayBord(board, ROW, COL);
		ret = IsWin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
	}
	if (ret == '*')
	{
		printf("玩家赢n");
	}
	else if (ret == '#')
	{
		printf("电脑赢n");
	}
	else
	{
		printf("平局");
	}
}

int main()
{
	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");
			break;
		default:
			printf("选择错误，请重新选择:>");
			break;
		}
	} while (input);
	return 0;
}

5.函数的实现

代码语言：javascript复制

#include "game.h"

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] = ' ';
		}
	}
}
//初始化棋盘
void DisplayBord(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  )
		{
			printf(" %c ", board[i][j]);
			if (j < col - 1)
				printf("|");
		}
		printf("n");//换行
		if (i < row - 1)
		{
			for (j = 0; j < col; j  )
			{
				printf("---");
				if (j < col - 1)
					printf("|");
			}
		}
		printf("n");
	}
}

void PlarerMove(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，请输入其他坐标n");
			}
		}
		else
		{
			printf("坐标非法，请重新输入n");
		}
	}
}

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;
		}
	}
}

static 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;
}

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][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[0][0];
	}
	if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
	{
		return board[1][1];
	}
	if (IsFull(board, row, col))
	{
		return 'Q';
	}
	return 'C';
}

到这里就结束了，希望对大家有所收获。
