C++控制台循环链表实现贪吃蛇

本文实例为大家分享了C++控制台循环链表实现贪吃蛇的具体代码，供大家参考，具体内容如下

-stdafx.h 为了简化程序定义一些宏和全局变量

#ifndef __STDAFX_H__
#define __STDAFX_H__

// ============上下左右=============
const int UP = 72;
const int DOWN = 80;
const int LEFT = 75;
const int RIGHT = 77;

// ==============宽高===============
#define HEIGHT 20
#define WIDTH 39

// ==============输出===============
#define cout_food std::cout<<"＊"
#define cout_snake std::cout<<"■"
#define cout_space std::cout << " "
#define cout_snake_xy(x,y) SnakeUI::gotoXY(x,y);cout_snake
#define cout_food_xy(x,y) SnakeUI::gotoXY(x,y);cout_food
#define cout_space_xy(x,y) SnakeUI::gotoXY(x,y);cout_space

// =============结束？==============
#define OVER false
#define RUN true

#endif

-SnakeUI.h 

主要是初始化UI，初始化蛇，还有生产食物，判断食物和蛇有没有相撞，还有对界面的一些操作

#ifndef __SNAKE_UI_H__
