一、游戏思路

        三子棋游戏是三个连着的棋为胜的一款游戏，c语言实现步骤如下：

        1.设计游戏菜单

        2.打印棋盘

        3.进行游戏

        4.判断游戏输赢

二、游戏框架

        1.游戏菜单

       通过一个menu函数设计一个游戏菜单

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

 菜单函数通过主函数进行判断

int main()
{
	int input = 0;
	srand((unsigned int)time(NULL));
	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，重新选择\n");
				break;
		}

	
	} while (input);
	return 0;
}

        2.游戏主体

                1.初始化棋盘

                        

void InitBoard(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] = ' ';
		}
	}
}

                 2.打印棋盘

                第一行中每三个空格就打印一个|

                第二行每打印---一次，就打印一次|，注意在循环过程中要减1否则会导致左边会多打印一次

void displayboard(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");
	}
}

        4.游戏进行

                1.玩家操作

                注意要进行判断所输入的数组是否越界

void Playermove(char board[ROW][COL], int row, int col)
{
	printf("玩家下棋");
	int x = 0;
	int y = 0;
	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("有棋子了，换地方下\n");
			}
		}
		else
		{
			printf("不在棋盘内，重新判断\n");
		}
	}
}

                 2.电脑操作

void computermove(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	printf("电脑下\n");
	while (1)
	{
		x = rand() % ROW;
		y = rand() % COL;
		if (board[x][y] == ' ')
		{
			board[x][y] = '#';
			break;
		}
	}
}

        5.判断输赢和平局

      

int is_full(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 0;
			}
		}
	}
	return 1;
}


char is_win(char board[ROW][COL], int row, int col)
{
	int i = 0;
	for ( i = 0; i < row; i++)
	{
		if (board[0][i] == board[1][i] && board[1][i] == board[2][i]&&board[1][i] != ' ')
		{
			return board[1][i];
		}
	}
	for ( i = 0; i < col; i++)
	{
		if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
		{
			return board[i][1];
		}
	}
	if (board[0][0]==board[1][1]&&board[1][1]==board[2][2] && board[1][1] != ' ')
	{
		return board[1][1];
	}
	if (board[2][0] == board[1][1] && board[1][1] == board[0][2]&&board[1][1] != ' ')
	{
		return board[1][1];
	}
	//平手
	if (1 == is_full(board,row,col))
	{
		return 'Q';
	}
	return'c';
}

 

        3.游戏运行函数

#pragma once
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#define ROW 3
#define COL 3
//函数的声明
void InitBoard(char board[ROW][COL],int row,int col);
//打印棋盘
void displayboard(char board[ROW][COL], int row, int col);
//下棋
void Playermove(char board[ROW][COL], int row, int col);
void computermove(char board[ROW][COL], int row, int col);
//判断输赢
char is_win(char board[ROW][COL], int row, int col);

三、游戏运行

 

四、所有代码
