想了解C语言贪吃蛇经典小游戏的相关内容吗，XHfight在本文为您仔细讲解C语言贪吃蛇的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：C语言,贪吃蛇，下面大家一起来学习吧。

一、贪吃蛇小游戏简介：

用上下左右控制蛇的方向，寻找吃的东西，每吃一口就能得到一定的积分，而且蛇的身子会越吃越长，身子越长玩的难度就越大，不能碰墙，也不能咬到自己的身体，等到了一定的分数，就能过关。

二、函数框架

三、数据结构

typedef struct Snake 
{ 
 size_t x; //行 
 size_t y; //列 
 struct Snake* next; 
}Snake, *pSnake;

定义蛇的结构体，利用单链表来表示蛇，每个结点为蛇身体的一部分。

四、代码实现（vs2010  c语言）

1.Snake.h

#ifndef __SNAKE_H__ 
#define __SNAKE_H__ 
 
#include <stdio.h> 
#include <stdlib.h> 
#include <Windows.h> 
#include <time.h> 
#include <malloc.h> 
#include <assert.h> 
//标识地图大小 
#define ROW_MAP 10 //地图的行 
#define COL_MAP 20 //地图的列 
#define SUCCESS_SCORE 10//通关分数 
enum Direction //蛇行走的方向 
{ 
 R, //右 
 L, //左 
 U, //上 
 D //下 
}Direction; 
 
enum State 
{ 
 ERROR_SELF, //咬到自己 
 ERROR_WALL, //撞到墙 
 NORMAL, //正常状态 
 SUCCESS //通关 
}State; 
 
typedef struct Snake 
{ 
 size_t x; //行 
 size_t y; //列 
 struct Snake* next; 
}Snake, *pSnake; 
 
 
void StartGame(); 
void RunGame(); 
void EndGame(); 
 
#endif

2.Snake.c
