【零天赋C语言】——三子棋小游戏

今天来利用C语言写一个三子棋小游戏，代码整体逻辑较为简单。

代码分为三个部分：

一、测试游戏的逻辑：

#include "game.h"

void menu()
{
	printf("**************************\n");
	printf("*******   1:play  ********\n");
	printf("*******   0:exit  ********\n");
	printf("**************************\n");
}
void game()
{
	char ret = 0;
	char board[ROW][COL] = { 0 };
	//初始化棋盘
	Init_board(board, ROW, COL);
	//打印棋盘
	Display_board(board, ROW, COL);
	while (1)
	{
		//玩家下棋
		Player_move(board, ROW, COL);
		Display_board(board, ROW, COL);
		//判断输赢
		ret = Iswin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
		//电脑下棋
		Computer_move(board, ROW, COL);
		Display_board(board, ROW, COL);
		ret = Iswin(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
	}
	if (ret == '#')
	{
		printf("玩家赢\n");
	}
	if (ret == '$')
	{
		printf("电脑赢\n");
	}
	if(ret == 'Q')
	{
		printf("平局\n");
	}
	Display_board(board, ROW, COL);
}
int main()
{
	srand((unsigned int)time(NULL));
	int input = 0;
	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("输入错误，请重新输入\n");
		}
	} while (input);
	return 0;
}

二、 游戏的实现：

#include "game.h"

//初始化棋盘
void Init_board(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col; j++)
		{
			board[i][j] = ' ';
		}
	}
}
//打印棋盘
void Display_board(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	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_move(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	printf("玩家走：");
	while (1)
	{
		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] = '#';
				break;
			}
			else
			{
				printf("坐标已被占用，请重新输入：");
			}
		}
		else
		{
			printf("坐标非法，请重新输入:");
		}
	}
}
void Computer_move(char board[ROW][COL], int row, int col)
{
	printf("电脑走\n");
	Sleep(1000);
	while (1)
	{
		int x = rand() % row;
		int y = rand() % col;
		if (board[x][y] == ' ')
		{
			board[x][y] = '$';
			break;
		}
	}
}

int Isfull(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col; j++)
		{
			if (board[i][j] == ' ')
			{
				return 1;
			}
		}
	}
	return 0;
}
char Iswin(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	//判断三行
	for (i = 0; i < row; i++)
	{
		if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
		{

			return board[i][0];
		}
	}
	for (i = 0; i < col; i++)
	{
		if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ')
		{
			return board[0][i];
		}
	}
	if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ')
	{
		return board[0][0];
	}
	if (board[0][2] == board[1][1] && board[1][1] == board[2][1] && board[1][1] != ' ')
	{
		return board[0][2];
	}
	int ret = Isfull(board, ROW, COL);
	if (ret == 1)
	{
		return 'C';
	}
	else
		return 'Q';
}

三、函数的声明和符号的定义：

#pragma once


#include 
#include 
#include 
#include 


#define ROW 3
#define COL 3

//初始化棋盘
void Init_board(char board[ROW][COL], int row, int col);
//打印棋盘
void Display_board(char board[ROW][COL], int row, int col);

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

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

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


//如果玩家赢———返回'#'
//如果电脑赢———返回'$'
//平局——————返回'Q'
//棋盘未满————返回'C'
