1.游戲介紹

三子棋是一種民間傳統游戲,又叫九宮棋、圈圈叉叉、一條龍等，將正方形對角線連起來,相對兩邊依次擺上三個雙方棋子,只要將自己的三個棋子走成一條線,對方就算輸了，

2.游戲效果

3.源代碼

(1)頭檔案命名為為game.h

主要是整個程式中函式的宣告

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#define ROW 3 //行
#define COL 3 //列
void BoardInit(char board[ROW][COL], int row, int col);
//棋盤展示
void BoardShow(char board[ROW][COL], int row, int col);
//人下一個位置用M表示，電腦下一個位置用C表示
void PlayerMove(char board[ROW][COL], int row, int col);
void ComputerMove(char board[ROW][COL], int row, int col);
//如果人贏回傳M   電腦贏回傳C   平局回傳Q
char IsWin(char board[ROW][COL], int row, int col);
char IsFull(char board[ROW][COL], int row, int col);

(2)游戲檔案命名為game.c

主要是三子棋游戲的實作

#include"game.h"
#include<stdlib.h>
//棋盤初始化
void BoardInit(char board[ROW][COL], int row, int col)
{
	for (int i = 0; i < row; i++)
	{
		for (int j = 0; j < col; j++)
		{
			board[i][j] = ' ';
		}
	}
}
//棋盤展示
void BoardShow(char board[ROW][COL], int row, int col)
{
	for (int i = 0; i < row; i++)
	{
		printf("-------------------\n");
		printf("|     |     |     |\n");
		printf("|     |     |     |\n");
		for (int j = 0; j < col; j++)
	{
		printf("   %c  ",board[i][j]);
		
	}
		printf("\n");
	}
	printf("-------------------\n");
}
//玩家下子
void PlayerMove(char board[ROW][COL], int row, int col)
{
	int x, y;
	while (1)
	{
		printf("請輸入你要下的坐標:>");
		scanf_s("%d %d", &x, &y);
		//對玩家落子坐標判斷
		if (x > row || y > col || x < 0 || y < 0)
		{
			printf("非法輸入請重新輸入\n");
			continue;
		}
		else if (board[x][y] != ' ')
			{
				printf("此位置已落子，請重新輸入!\n");
				continue;
			}
		//滿足落子要求回傳M
			else
			{
				board[x][y] = 'M';
				return 'M';
				break;
			}
		}
	}
//電腦下子
void ComputerMove(char board[ROW][COL], int row, int col)
{
	srand(time(NULL));
	while (1)
	{
		int x = rand() % 3;
		int y = rand() % 3;
		//滿足落子要求回傳C
			if (board[x][y] != " ")
			{
				board[x][y] = 'C';
				return 'C';
				break;
			}
		}
}
//判斷棋盤是否被下滿
char IsFull(char board[ROW][COL], int row, int col)
{
	for (int i = 0; i < row; i++)
	{
		for (int j = 0; j < col; j++)
		{
			if (board[i][j] == ' ')
			{
				return 0;
			}
		}
	}
		return 'Q';  //滿了
	
}
//輸贏判斷
char IsWin(char board[ROW][COL], int row, int col)
{
	//橫行三個連子贏
	for (int i = 0; i < row; i++)
	{
		if (board[i][0] == board[i][1] && board[i][1] == board[i][2])
		{
			if (board[i][0] == 'M')
			{
				return 'M';
			}
			else if (board[i][0] == 'C')
			{
				return 'C';
			}
		}
	}
	//豎行三個個連子贏
	for (int i = 0; i < col; i++)
	{
		if (board[0][i] == board[1][i] && board[1][i] == board[2][i])
		{
			if (board[0][i] == 'M')
			{
				return 'M';
			}
			else if (board[0][i] == 'C')
			{
				return 'C';
			}
		}
	}
	// 斜向"\"這樣三個連子贏
	if (board[0][0] == board[1][1] && board[1][1] == board[2][2])
	{
		if (board[1][1] == 'M')
		{
			return 'M';
		}
		else if (board[1][1] == 'C')
		{
			return 'C';
		}
	}
	// 斜向"/"這樣三個連子贏
	if (board[0][0] == board[1][1] && board[1][1] == board[2][2])
	{
		if (board[1][1] == 'M')
		{
			return 'M';
		}
		else if (board[1][1] == 'C')
		{
			return 'C';
		}
	}
	//判斷平局，即棋盤下滿為平局
	if ((IsFull(board, ROW, COL)) == 1)
	{
		return 'Q';
	}
	return 1;
}

(3)測驗檔案命名為test.c

主要實作程式的測驗

#include<stdio.h>
#include "game.h"
#include<stdlib.h>
// 目錄
void meun()
{
	printf("********************************\n");
	printf("************1.三子棋************\n");
	printf("************2.五子棋************\n");
	printf("************0.退出**************\n");
	printf("********************************\n");
}
//三子棋
void ThressChess()
{
	char board[ROW][COL];
	BoardInit(board, ROW, COL);
	BoardShow(board, ROW, COL);
	char ret = IsWin(board, ROW, COL);
	while (1)
	{
		//對玩家下的做判斷
		printf("玩家出手\n");
		PlayerMove(board, ROW, COL);
		BoardShow(board, ROW, COL);
		ret = IsWin(board, ROW, COL);
		if (ret == 'C')
		{
			printf("電腦贏了\n");
			break;
		}
		else if (ret == 'M')
		{
			printf("恭喜你贏了！\n");
			break;
		}
		else if (ret == 'Q')
		{
			printf("平局\n");
			break;
		}
		//對電腦下的做判斷
		ComputerMove(board, ROW, COL);
		BoardShow(board, ROW, COL);
		ret = IsWin(board, ROW, COL);
		if (ret == 'M')
		{
			printf("恭喜你贏了！\n");
			break;
		}
		else if (ret == 'C')
		{
			printf("電腦贏了\n");
			break;
		}
		else if (ret == '1')
		{
			printf("平局\n");
			break;
		}
		else
		{
			printf("繼續\n");
		}
	}
}
int main()
{
	int input;
	srand(time(NULL));
	do
	{
		meun();
		printf("請選擇：");
		scanf_s("%d", &input);
		switch (input)
		{
		case 1:
			ThressChess();
			break;
		case 2:
			printf("正在研發，敬請期待！\n");
			break;
		case 0:
			printf("按任意鍵退出\n");
			break;
		default:
			printf("非法輸入，請重新輸入\n");
			break;
		}
	} while (input);
	return 0;
}
