[C language] Three-pointed chess (classic solution + list diagram)

什么是三子棋？

Three-piece chess is in3*3的棋盘中,Both sides carry out containment and ideas,One side reaches the connection first3A pawn is a victory;

Backgammon needs to be masteredCwhere the language is？

According to the author's process of completing three pieces of chess,Backgammon only needs to be mastered二维数组即可.

How to implement three pieces？

1.头文件（函数声明）

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

#define ROW 3
#define COL 3

void menu();

void Init_board(char board[ROW][COL],int row,int col);//初始化数组为空格

void display_board(char board[ROW][COL],int row, int col);//展示数组

void Player(char board[ROW][COL], int row, int col);//玩家下棋

void Computer(char board[ROW][COL],int row,int col);//电脑下棋

char Iswin(char board[ROW][COL],int row,int col);//判断输赢

2.game.c（函数实现）

#define _CRT_SECURE_NO_WARNINGS 1

#include"game.h"

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

void Init_board(char board[ROW][COL], int row, int col)//初始化数组为空格
{
    
	int i, j;
	for (i = 0; i < row; i++)
	{
    
		for (j = 0; j < col; j++)
		{
    
			board[i][j] = ' ';
		}
	}
}

void display_board(char board[ROW][COL], int row, int col)//展示棋盘
{
    
	int i, j;
	for (i = 0; i < row; i++)
	{
    
		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");
		}
	}
}

void Player(char board[ROW][COL], int row, int col)//玩家下棋
{
    
	int x, y;
	while (1)
	{
    
		printf("玩家下棋:>");
		scanf("%d%d", &x, &y);
		//判断合法性
		if ((x >= 1 && x <= row)&& (y >= 1 && y <= col))
		{
    
			//Determine if there is a chess piece
			if (board[x-1][y-1] == ' ')
			{
    
				board[x-1][y-1] = '*';
				break;
			}
			else
			{
    
				printf("This location is already occupied,请重新输入\n");
			}
		}
		else
		{
    
			printf("输入非法,请重新输入:>\n");
		}
	}
}

void Computer(char board[ROW][COL], int row, int col)//电脑下棋
{
    
	printf("电脑下:>\n");
	int x, y;
	while (1)
	{
    
		x = rand() % row;
		y = rand() % col;
		//Determine if there is a chess piece
		if (board[x][y] == ' ')
		{
    
			board[x][y] = '#';
			break;
		}
		else
		{
    
			;
		}
	}
}

char  Iswin(char board[ROW][COL], int row, int col)//判断输赢
{
    
	//玩家赢
	int i;
	for (i = 0; i < row; i++)
	{
    
		if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] == '*')
		{
    
			return '*';
		}
		if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] == '*')
		{
    
			return '*';
		}
	}
	if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[2][2] == '*')
	{
    
		return '*';
	}
	if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[2][0] == '*')
	{
    
		return '*';
	}
	//电脑赢
	for (i = 0; i < row; i++)
	{
    
		if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] == '#')
		{
    
			return '#';
		}
		if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] == '#')
		{
    
			return '#';
		}
	}
	if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[2][2] == '#')
	{
    
		return '#';
	}
	if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[2][0] == '#')
	{
    
		return '#';
	}
	//平局
	int flag = 0;
	for (i = 0; i < row; i++)
	{
    
		int j = 0;
		for (j = 0; j < col; j++)
		{
    
			if (board[i][j] == ' ');
			flag++;
		}
	}
	if (flag == 0)
	{
    
		return 'Q';
	}
	else
		return 'C';
}

3.text.c（三子棋的测试）

#define _CRT_SECURE_NO_WARNINGS 1
#include"game.h"

void game()
{
    
	char ret;
	char board[ROW][COL] = {
    "0"};//创建数组
	Init_board(board, ROW, COL);//初始化数组为空格
	display_board(board, ROW, COL);//展示棋盘
	while (1)
	{
    
		Player(board, ROW, COL);//玩家下棋
		ret = Iswin(board, ROW, COL);//判断输赢
		if (ret != 'C')
			break;
		display_board(board, ROW, COL);//打印棋盘

		Computer(board, ROW, COL);//电脑下棋
		ret = Iswin(board, ROW, COL);//判断输赢
		if (ret != 'C')
			break;
		display_board(board, ROW, COL);//打印棋盘
	}
	if (ret == '*')
	{
    
		printf("玩家赢\n");
		display_board(board, ROW, COL);//打印棋盘
	}
	else if (ret == '#')
	{
    
		printf("电脑赢\n");
		display_board(board, ROW, COL);//打印棋盘
	}
	else
	{
    
		printf("平局\n");
		display_board(board, ROW, COL);//打印棋盘s
	}
}
int main()
{
    
	int input = 0;
	srand((unsigned int)time(NULL));//设置时间戳
	do
	{
    
		menu();
		printf("请选择:>");
		scanf("%d", &input);
		switch (input)
		{
    
		case 1:
			game();
			break;
		case 0:
			printf("游戏结束\n");
			break;
		default:
			printf("输入错误,请重新选择:>");
			break;
		}
	} while (input);
	return 0;
}

An overview idea of ​​chess code

The code block of the main function is the basic routine,Just know how to do it.
如下：

int main()
{
    
	int input = 0;
	srand((unsigned int)time(NULL));//设置时间戳
	do
	{
    
		menu();
		printf("请选择:>");
		scanf("%d", &input);
		switch (input)
		{
    
		case 1:
			game();
			break;
		case 0:
			printf("游戏结束\n");
			break;
		default:
			printf("输入错误,请重新选择:>");
			break;
		}
	} while (input);
	return 0;
}

An overview of the three-piece game is as follows,即game（）函数的实现：

1. 创建二维数组

2. Initialize all spaces

3. 打印棋盘

4. While(1)
   {
   玩家下棋
   判断输赢
   展示棋盘

   电脑下棋
   判断输赢
   展示棋盘
   }

加油呀！
