一 : 总体代码结构

二 : 分步实现代码功能(详解)

总体代码结构思想

1.进入游戏时菜单以及选择选项

2.选择选项之后游戏进行开始

3.玩家下棋,并且判定胜负

4.电脑下棋,并且判定胜负

5.游戏结果返回

分步实现代码功能

? 1.进入游戏时菜单以及选择选项

void menu()//菜单
{
	printf("******************************\n");
	printf("**********1.开始游戏**********\n");
	printf("**********0.退出游戏**********\n");
	printf("******************************\n");
}
void test()
{
	int input = 0;
	srand((unsigned int)time(NULL));//用于进入游戏后电脑下棋的随机值设置
	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("选择错误,请重新选择!\n");
			break;
		}

	} while (input);
}


int main()
{
	test();

	return 0;
}

2.选择选项之后游戏程序开始

1.先创建好整体棋盘框架再去把功能一步步实现 由棋盘生成-->棋盘初始-->打印棋盘-->玩家开始下棋-->判断胜负-->电脑下棋-->判断胜负

void game()
{
	char board [ROW][COL] = { 0 };
	//初始化棋盘
	InitBoard(board, ROW, COL);
	//打印棋盘
	DisplayBoard(board, ROW, COL);
	char ret = 0;
	while (1)
	{
		//玩家下
		player_move(board, ROW, COL);//玩家下棋
		DisplayBoard(board, ROW, COL);//玩家下棋之后打印棋盘
		ret = Iswin(board, ROW, COL);//Iswin为判断胜负,ret用于接收函数调用返回的值进行判断
		if (ret != 'C')
		{
			break;
		}
		//电脑下
		computer_move(board, ROW, COL);//电脑下棋
		DisplayBoard(board, ROW, COL);//电脑下棋之后打印棋盘
		//判定输赢
		ret = Iswin(board, ROW, COL);//Iswin为判断胜负,ret用于接收函数调用返回的值进行判断
		if (ret != 'C')
		{
			break;
		}
	}
	if (ret == '*')
	{
		printf("玩家赢\n");
	}
	else if (ret == '#')
	{
		printf("电脑赢\n");
	}
	else
		printf("平局\n");


}

?2.功能函数的声明与头文件创建

#pragma once
#include <stdio.h>//在头文件里包含,在功能实现以及框架工程里包含此头文件即可
#include <time.h>
#include <stdlib.h>

#define ROW 3//行数常量
#define COL 3//列数常量

void InitBoard(char board[ROW][COL],int row, int col);//初始化棋盘
void DisplayBoard(char board[ROW][COL], int row, int col);//打印棋盘
void player_move(char board[ROW][COL], int row, int col);//玩家下
void computer_move(char board[ROW][COL],int row, int col);//电脑下
char Iswin(char board[ROW][COL], int row, int col);//判定输赢

3.功能函数具体实现

·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] = ' ';
		}
	}
}

?·打印棋盘

void DisplayBoard(char board[ROW][COL], int row, int col)//打印棋盘
{
	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)
		{
			for (j = 0; j < col; j++)
			{
				printf("---");
				if (j < col - 1)
					printf("|");
			}
		}
		printf("\n");
	}
}

·玩家下棋

void player_move(char board[ROW][COL], int row, int col)//玩家下棋
{
	printf("玩家下棋 ");
	int i = 0;
	int j = 0;
	while (1)
	{
		scanf("%d %d", &i, &j);
		if (i >= 1 && i <= row && j >= 1 && j <= col)
		{
			if (board[i - 1][j - 1] == ' ')
			{
				board[i - 1][j - 1] = '*';
				break;
			}
			else
				printf("此坐标已被占用,请重新输入");
		}

	}
}

·电脑下棋

void computer_move(char board[ROW][COL], int row, int col) //电脑下棋
{
	int a = 0;
	int b = 0;
	printf("电脑下:>\n");
	while (1)
	{
		a = rand() % ROW;
		b = rand() % COL;
		if (board[a][b] == ' ')
		{
			board[a][b] = '#';
			break;
		}
	}

}

·判断输赢与是否平局

int IsFull(char board[ROW][COL], int row, int col)//判断是否平局
{
	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)//判断输赢
{
	int i = 0;
	for (i = 0; i < row; i++)//判断行
	{
		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++)//判断列
	{
		if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] != ' ')
			return board[i][0];
	}

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

	//判断平局
	if (1 == IsFull(board, row, col))
	{
		return 'Q';
	}
	return 'C';

}
