一个小时完成贪吃蛇

突然想玩贪吃蛇，所以花了大概个小时写了一个，还可以原地转掉头。主要大概的想法就是，定义一个图片数组，然后用打印，清屏的方法实现显示，并且不断进行按键检测，准备用、c++语法写，但是C风格很严重。希望大神批评指正！

#include 
#include 
#include 

using namespace std;

//按键检测宏
#define KEY_DOWN(VK_NONAME) ((GetAsyncKeyState(VK_NONAME) & 0x8000) ? 1:0)

//图像高度，宽度
#define hight 30
#define weight 30
//图像数组
char image[hight][weight];
//小蛇行进方向
char fangxaing = 'D';
//记录得分
int fenshu = 0;
//食物结构体
typedef struct food {
	int x;
	int y;
	bool statu;
}*Food;

//双向链表节点，保存小蛇坐标
typedef struct node {
	node *next;
	node *front;
	int x;
	int y;
}*Node;
//保存小蛇头，尾节点
typedef struct snack {
	Node head;
	Node tail;
	int length;
}*Snack;
//生成最初食物坐标
bool Foodinit(Food &fd1)
{
	fd1 = (Food)malloc(sizeof(food));

	fd1->statu = true;
	fd1->x = (rand() % (weight - 2) + 1);
	fd1->y = (rand() % (hight - 2) + 1);
	image[fd1->y][fd1->x] = '@';
	return true;
}
//判断食物是否被吃下
