C语言实现AI五子棋 怎样利用最简单的C语言实现AI五子棋

想了解怎样利用最简单的C语言实现AI五子棋的相关内容吗，Ja_king_在本文为您仔细讲解C语言实现AI五子棋的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：C语言实现五子棋,c语言做五子棋,C语言实现简单的五子棋代码，下面大家一起来学习吧。

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

在这里插入图片描述

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。

在这里插入图片描述

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）

在这里插入图片描述

打印棋盘：

效果如下：

（3）玩家下子

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

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\n");
	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

		}
		
	}
	//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++;

		}

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

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

		}
	}
	if (ret == 'o')

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

（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);

四.具体效果

1.棋盘打印以及选择先后手

在这里插入图片描述

2.玩家和电脑下子

在这里插入图片描述

3.判断输赢

在这里插入图片描述

此处我们看到玩家赢了，可是电脑实在太蠢了，所以还有很多地方需要添加的

欢迎各位大佬对此代码进行优化！
