贪吃蛇~~C++控制台实现！

刚学完了C语言，便尝试的写了贪吃蛇的代码，但是效果不佳，很多的bug，所以，这个学了C++，便重新的写了这个小游戏，用类来封装！~

先是头文件：

struct Snake
{
	int x, y;
};
class snake
{
public:
	snake()                             //构造函数
	{
		length = 3;
		s[2].x = 10;
		s[2].y = 10;
		s[1].x = 9;
		s[1].y = 10;
		s[0].x = 8;
		s[0].y = 10;
		up = right = left = down = 0;
	}
	~snake(){}
	void display();                    //显示蛇身函数
	void Rightmove();                  //右移函数
	void Leftmove();                   //左移函数
	void Upmove();                     //上移函数
	void Downmove();                   //下移函数
	int cheak();                       //检查是否撞墙或撞到自身
	void creat_food();                 //产生食物
	int eat_food();                    //吃食物
private:
	struct Snake s[100];               //先定义蛇身最长100
	int length;                        //当前蛇长度
	int x3, y3;                        //食物坐标
	int up, down, right, left;         //蛇的状态，是上移还是下移或...
};

void make_frame();                     //打印框架的函数
void show();                           //游戏开始倒计时函数
void gameover();                       //游戏结束函数

下面是各个函数的实现的cpp文件：

	pos.X = x;
	pos.Y = y;
	SetConsoleCursorPosition(hOut, pos);
}

	{

	}

下面是游戏的截图：

控制台的实现，不是很美观，主要是由于上下和左右的间隙不一样大，所以看起来不是很好看，但总体还是实现了贪吃蛇！~

有什么好的意见，可以跟我提！！
