C语言小游戏——三子棋

首先创建三个文件

test.c——测试的逻辑

(比如说这个游戏怎么开始,玩家电脑怎么下棋,整个逻辑在这个文件里形成)

game.h  game.c——游戏模块 ,游戏的实现

(游戏的过程等)

游戏模块代码被测试模块的代码使用

test.c

#include
#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];
	//初始化棋盘为全空格
	init_board(board, Row, Col);
	print_board(board, Row, Col);
	
	while (1)
	{
		player_move(board, Row, Col);
		print_board(board, Row, Col);
		//判断输赢
		 ret = is_win(board, Row, Col);
		if (ret != 'C')

	}
	if (ret == '#')

	}

	{
		printf("玩家赢了\n");
	}
	else if (ret == 'Q')
	{

	}
}

//判断输赢
//判断输赢的代码要告诉我:电脑赢了?玩家赢了?玩家赢?继续游戏?
//电脑赢 #   玩家赢 *  平局 Q  游戏继续 C
