C语言实现，编译环境VS２０１７
效果图如下
（有一些函数ｋｂｈｉｔ，ｇｅｔｃｈ，在这表示为＿ｋｂｈｉｔ与＿ｇｅｔｃｈ）

一、引言
作为一个小白，相信大家的心情都是一样的，渴望写一个人生的第一个“贪吃蛇”。
在网上看了基本思路后，如果有一定的知识（链表的相关操作），写出这个应该是不难的。
１、背景
打印游戏背景框，以及一些初设的东西，如蛇的初始长度，可以的话可以自己加上出场界面
２、食物产生
通过ｓｒａｎｄ，与ｒａｎｄ函数实现随机产生
３、键盘信号获取
由＿ｋｂｈｉｔ（），＿ｇｅｔｃｈ（），函数获取
４、蛇的移动
分为普通移动与吃到食物的移动
ｐｓ．（许多网上通过刷屏实现，其实可以靠覆盖实现，将原来蛇覆盖用空格，然后重新打印蛇）
二、一些必要函数
打印这个并不是图形库实现，所以要通过光标跳转实现打印
注：此方法我也不清楚是从网上查阅资料所得，目前还是小白(ง •_•)ง
void gotoxy(int x, int y)
{
COORD pos;
HANDLE hOutput;
pos.X = x;
pos.Y = y;
hOutput = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleCursorPosition(hOutput, pos);
}
应该是获取窗口句柄
详细可以参考

三、不多说，看代码
#include<stdio.h>
#include<string.h>
#include<Windows.h>
#include<time.h>
#include<conio.h>
#define up 'w'
#define down 's'
#define left 'a'
#define right 'd'
#define stop 'p'
void welcome(); //55开始界面
void Finish(); //291结束界面
void creatgraph(); //69围墙打印
void gotoxy(int x, int y); //111光标跳转，横为X 0,1,2..
void gotoprint(int x, int y); //121跳转打印
void gotodelete(int x, int y); //127跳转删除
void creatfood(); //133食物产生
int ClickControl(); //157获取键盘信号
int Judge(); //270游戏结束判断
void MovingBody(char c); //172蛇的移动
void Eating(); //223蛇吃到东西后的操作（伸长）
void ChangeBody(int a,int b); //245蛇的坐标变换,后一个复制前一个STRUCT,a,b为head之前坐标
/*全局变量 + 预处理：*/
