如何利用最简单的C语言实现AI五子棋

一.如何实现

1.说明：由于本文只是对初学C语言的人学习，所以将不会涉及任何算法，电脑将采用随机下子的方式。（后期会为大家介绍Alpha-Beta剪枝算法实现人工智能AI）

2.主要部分：

（1）菜单

（2）打印棋盘

（3）玩家下子

（4）电脑下子

（5）判断输赢

 

二.实现代码及分析

 

（1）菜单的制作

如何利用最简单的C语言实现AI五子棋

运用do…while循环调用菜单，根据用户选择实现玩游戏和退出游戏

 

（2）棋盘的初始化和打印

棋盘采用标准的15*15的格子，我们可以宏定义ROW和COL分别为15和15来表示行和列。

如何利用最简单的C语言实现AI五子棋

分别封装两个函数对棋盘进行初始化和打印

初始化：（这里将棋盘初始化为空格，可初始化为其他）

如何利用最简单的C语言实现AI五子棋

打印棋盘：

（3）玩家下子

void PlayerMove(char board[ROW][COL], int row, int col) {
	int x, y;
	while (1) {
		printf("玩家走：
");
		printf("请输入坐标：
");
		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] = "O";
				break;
			}
			else {
				printf("坐标被占用，请重新输入
");
			}
		}
		else {
			printf("坐标非法，请重新输入
");
		}
	}
}

玩家下子主要采用的思路是，判断棋盘上是否有子，已经输入的坐标是否合法。

 

（4）电脑下子

void ComputerMove(char board[ROW][COL], int row, int col) {
	int x, y;
	printf("电脑走
");
	while (1) {
		x = rand() % row;
		y = rand() % col;
		if (board[x][y] == " ") {
			board[x][y] = "X";
			break;
		}
	}
}

与玩家下子相同，此处采用的随机下子，后期可进行优化（比如：极大极小值算法、Alpha-Beta剪枝算法等）

 

（5）判断输赢

通过遍历整个棋盘，观察是否有连五子情况出现，代码如下：

char iswin(char board[ROW][COL], int row, int col) {
	//行
	int ren=0,dian=0,i,j;
	for (i = 0;i < row;i++) {
		ren = 0;
		for (j = 0;j < col;j++) {
			if (board[i][j] == "O")
				ren++;
			else
				ren = 0;
			if (ren >= 5)
				return "o";
		}
		
	}
	for (i = 0;i < row;i++) {
		dian = 0;
		for (j = 0;j < col;j++) {
			if (board[i][j] == "X")
				dian++;
			else
				dian = 0;
			if (dian >= 5)
				return "x";
		}
		
	}
	//列
	ren = dian = 0;
	for (i = 0;i < row;i++) {
		ren = 0;
		for (j = 0;j < col;j++) {
			if (board[j][i] == "O")
				ren++;
			else
				ren = 0;
			if (ren >= 5)
				return "o";
		}
		
	}
	for (i = 0;i < row;i++) {
		dian = 0;
		for (j = 0;j < col;j++) {
			if (board[j][i] == "X")
				dian++;
			else
				dian = 0;
			if (dian >= 5)
				return "x";
		}
		
	}
	//右下
	ren = dian =i=j= 0;
	for (int k = 0;k < row;k++) {
		i = k;
		j = 0;
		ren = 0;
		while (i < row && j < col) {
			if (board[i][j] == "O") {
				ren++;
			}
			else {
				ren = 0;
			}
			i++;
			j++;
			if (ren >= 5)
				return "o";
		}
		
	}
	i = j = 0;
	for (int k = 0;k < row;k++) {
		i = k;
		j = 0;
		dian = 0;
		while (i < row && j < col) {
			if (board[i][j] == "X") {
				dian++;
			}
			else
				dian = 0;
			i++;
			j++;
			if (dian >= 5)
				return "x";
		}
		
	}
	//右上
	for (int k = row;k >=0;k--) {
		j = col;
		i = k;
		ren = 0;
		while (i >=0 && j >=0) {
			if (board[i][j] == "O") {
				ren++;
			}
			else
				ren = 0;
			i--;
			j--;
			if (ren >= 5)
				return "o";
		}

	}
	
	for (int k = row;k >= 0;k--) {
		i = k;
		j = col;
		dian = 0;
		while (i >= 0 && j >= 0) {
			if (board[i][j] == "X") {
				dian++;
			}
			else
				dian = 0;
			i--;

		}
		
	}
	for (int k = row;k >= 0;k--) {
		i = k;

			if (dian >= 5)
				return "o";
		}

	}
	for (int k = row;k >= 0;k--) {
		i = k;
		j = 0;
		dian = 0;
		while (i >= 0 && j <col) {
			if (board[i][j] == "X") {
				dian++;
			}
			else
				dian = 0;
			i--;
			j++;
			if (dian >= 5)
				return "x";
		}

	}
	for (int k = 0;k < row;k++) {
		i = k;
		j = col;
		dian = 0;
		while (i < row && j >= 0) {

		}

	}
	for (int k = 0;k <row;k++) {
		i = k;

			else
				dian = 0;
			i++;
			j--;
			if (dian >= 5)
				return "x";
		}

	}
	return "c";
	//左
}

 

三.整个代码

 

（1）test.c文件下代码：

#define _CRT_SECURE_NO_WARNINGS 1
#include"game.h"
void menu() {
	printf("**************************
");
	printf("******* 1. play  *********
");
	printf("******* 0. exit  *********
");
	printf("**************************
");
}
void game() {
	//棋盘数组
	char board[ROW][COL],ret;
	//初始化棋盘
	InitBoard(board, ROW, COL);
	//打印棋盘
	PrintBoard(board, ROW, COL);
	//下棋
	int a;
	printf("1.先手 0.后手");
	scanf("%d", &a);
	if(a==1)
		PlayerMove(board, ROW, COL);
	else
		ComputerMove(board, ROW, COL);
	while (1) {
		if (a == 0) {
			//PlayerMove(board, ROW, COL);
			PlayerMove(board, ROW, COL);
			PrintBoard(board, ROW, COL);
			ret=iswin(board, ROW, COL);
			if (ret != "c") {
				break;
			}
			//ComputerMove(board, ROW, COL);
			ComputerMove(board, ROW, COL);
			PrintBoard(board, ROW, COL);
			ret = iswin(board, ROW, COL);
			if (ret != "c") {
				break;
			}
		}
		else {
			//ComputerMove(board, ROW, COL);
			ComputerMove(board, ROW, COL);
			PrintBoard(board, ROW, COL);
			ret = iswin(board, ROW, COL);
			if (ret != "c") {
				break;
			}
			//PlayerMove(board, ROW, COL);
			PlayerMove(board, ROW, COL);
			PrintBoard(board, ROW, COL);
			ret = iswin(board, ROW, COL);
			if (ret != "c") {
				break;
			}
		}
	}
	if (ret == "o")
		printf("玩家赢
");
	else if (ret == "x")
		printf("电脑赢
");
	else
		printf("平局
");
}
int main() {
	int input;
	srand((unsigned int)time(NULL));
	do {
		menu();
		scanf("%d", &input);
		switch (input) {
		case 1:
			game();
			break;
		case 0:
			printf("退出游戏
");
			break;
		default:
			printf("选择错误
");
			break;
		}
	} while (input);
	return 0;
}

 

（2）game.c下的代码

#define _CRT_SECURE_NO_WARNINGS 1

	}
	printf("
");
	for (int i = 0;i < row;i++) {
		//打印数据
		printf("%2d", i + 1);
		for (int j = 0;j < col;j++) {
			printf(" %c ", board[i][j]);
			if (j < col - 1)
				printf("|");
		}

（3）game.h下的代码

#pragma once
#define ROW 15
#define COL 15
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
//初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col);
//打印棋盘
void PrintBoard(char board[ROW][COL], int row, int col);
//人走
void PlayerMove(char board[ROW][COL], int row, int col);
//电脑走
void ComputerMove(char board[ROW][COL], int row, int col);
//判断输赢
char iswin(char board[ROW][COL], int row, int col);
