教你制作属于自己的C语言版贪吃蛇！

贪吃蛇？
　　没错，就是贪吃蛇，这个你不会不知道吧。那你肯定会疑问了，还能用代码写贪吃蛇？当然啦，今天我就教大家写一个属于自己的贪吃蛇！
　　你所需要准备的是：一定的链表知识，电脑集成编译环境CodeBlocks（最好使用该软件，否则可能会不成功），点个赞，关注一波~~后续有好东西，我会继续分享的！

设计思路
　　首先，要先将背景打印出来，这里需要的函数下面会介绍。然后随机生成蛇头，根据蛇头生成蛇身，并将整个蛇打印出来，然后生成食物（确保不和蛇重合），这样，第一步就完成了。接下来，到了最主要的步骤了，蛇身移动及吃食。这里我采用的是先清除蛇身，再打印到移动后的位置，吃食同理。而蛇的方向控制需要键盘控制。

调用函数
void Menu(); 　　 //初始化菜单
void Gotoxy(int x, int y); 　　 //光标定位
void GotoChange(int x, int y); 　　//将■改为空格
void GotoPrint(int x, int y); 　　 //转至（x,y）打印■
void CreatWall(); 　　 //生成围墙
void CreatSnake(); 　　 //初始化生成蛇
void PrintBody(); 　　 //打印蛇身
void Initialization(); 　　 //初始化界面
void CreatFood(); 　　 //生成随机食物
int Control(); 　　 //控制蛇
int Judge(); 　　 //评判结束
void MovingBody(); 　　//移动蛇身
void ChangeBody(int x, int y); 　　//改变蛇身
void Eating(); 　　 //蛇“进食”
void End(); 　　 //结束页面
　　其中比较难理解且重要的函数可见：
gotoxy()函数——>传送门
Control()里的_kbhit()——>传送门
Control()里的_getch()——>传送门
未列出的变色函数SetConsoleTextAttribute——>传送门

代码实现：

#include<stdio.h>

#define up 'w'

#define left 'a'

#define stop 'p'

void CreatWall();       //生成围墙
void CreatSnake();        //初始化生成蛇
