小白的简易三子棋

为了提高代码的可读性，写该三子棋分了三个部分，test.c（表达自己的步骤），game.h(实现游戏代码块之前对函数的声明）game.c(游戏代码块的实现），在.c文件中对函数的实现需引用.h文件中的函数声明，例如使用库函数printf需使用头文件#include <stdio.h>，在.c 文件汇总都要使用到该库函数，可将该头文件放于game.h头文件中，在.c文件使用时引用用#include "game.h"即可，最终我们需要的是这么一个三子棋模板并在上面进行下棋，接下来进行分析

test.c

简易menu菜单

提示所要选择的数字

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

是否开始游戏

输入1开始游戏，0退出游戏，选择其他提示输入错误，则重新输入，为了可以进行游戏可以不止玩一把，则可以用do… while来保证游戏可进行

int main()
{
    
    
	int input = 0;
	srand((unsigned int)time(NULL));
	do
	{
    
    
		menu();//游戏菜单
		printf("请输入：>");
		scanf("%d", &input);
		switch (input)//判断是否开始游戏
		{
    
    
		case 1:
			printf("游戏开始\n");
			game();
			break;
		case 0:
			printf("退出游戏\n");
			break;
		default:
			printf("选择错误，重新输入\n");
			break;
		}
	} while (input);
	return 0;
}

进入游戏

建立二维数组，用该数组来进行初始化棋盘，将数组，数组的行、列传给形参，同理打印棋盘，进行游戏当中都需要使用到数组所建立的棋盘，因此都要将该数组、行、列传给形参，棋盘初始化打印好后，进行下棋环节，下棋不止下一个棋子，分玩家下，电脑下，因此需要一个循环来控制下棋的重复性顺序，将玩家赢和电脑赢以及平局分别用字符来代替，满足谁赢的条件则返回相应的字符，否则继续游戏，直到平局。

void game()
{
    
    
	char ret;
	char board[3][3] = {
    
     0 };
	//初始化棋盘
	Initboard(board, ROW, COL);
	//打印棋盘
	Displayboard(board, ROW, COL);

	//1.玩家用*表示
	// 2.电脑用#表示
	//判断输赢
	//1.玩家赢返回*
	//2.电脑赢返回#
	//3.继续游戏返回C
	//4.平局返回P
	while (1)
	{
    
    
		//玩家下棋
		PlayerMove(board, ROW, COL);
		Displayboard(board, ROW, COL);
		//判断输赢
		ret = IsWin(board, ROW, COL);
		if (ret != 'C')
			break;
		//电脑下棋
		ComputMove(board, ROW, COL);
		Displayboard(board, ROW, COL);
		//判断输赢
		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\n");
}

头文件声明，对要实现的函数进行声明

#define _CRT_SECURE_NO_WARNINGS 1

game.c

函数的具体实现

初始化棋盘

初始化棋盘为空格，打印棋盘模样后，进行下棋，谁赢返回谁输入的字符串，平局返回自定义的字符串

#include "game.h"

//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] = ' ';//初始化为空格
		}
	}
}

打印棋盘

，

void Displayboard(char board[ROW][COL], int row, int col)
{
    
    
	//打印数据和列
	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");
		//打印分割线
		if (i < row - 1)
		{
    
    
			int j = 0;
			for (j = 0; j < col; j++)
			{
    
    
				printf("---");
				if(j<col-1)
				printf("|");			
			}
		}
		printf("\n");
	}
}

玩家下棋

//玩家下棋
void PlayerMove(char board[ROW][COL], int row, int col)
{
    
    
	int i = 0;
	int j = 0;
	//输入坐标
	
	while (1)
	{
    
    
		printf("请输入坐标：");
		scanf("%d%d", &i, &j);
		//判断输入坐标合法性
		if (i - 1 >= 0 && i - 1 < row && j - 1 >= 0 && j - 1 < 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\n");
		}
		else
			printf("坐标非法，请重新输入\n");
	}
}

电脑下棋

//电脑下棋
void ComputMove(char board[ROW][COL], int row, int col)
{
    
    
	int x = 0;
	int y = 0;
	
	printf("电脑下：\n");
	while (1)

评价

该简易版三子棋存在很多不足，主要是小白水平不足，只能仿造写这么一个代码。
电脑玩家不能够拥有特定的下法，而是随机下，减少了趣味性，不能够控制谁先下的顺序，望大佬给予更多的指点
