墙壁；蛇；食物

墙壁模块

#pragma once
#include<iostream>

#include<vector>
#include<list>
using namespace std;
class Wall
{
public:
	enum
	{
		ROW=40,
		COL=40
	};

	//初始化墙壁
	void wallInit();

	//显示墙壁
	void showWall();

	//设置墙壁内同
	void setWall(int x,int y,char c);
	//查看墙壁内容
	char getWall(int x,int y);


	char gameArry[ROW][COL];

蛇模块

#pragma once 
#include"wall.h"
#include"food.h"

class Snake

	//初始化蛇
	void snakeInit();

	//销毁蛇
	void destroy();

	//增加节点
	void addNode(int x,int y);
	//删除尾节点节点
	void deleteNode();
	//移动
	bool move(char key);

     Node* pHead;

食物模块
