這篇文章主要為大家詳細介紹了C語言實現——《進化版貪吃蛇項目》，也就是在我們上一個發布的文章項目分享的基礎上，實現貪吃蛇的自動行動，你可以按鍵也可以不按鍵，讓蛇自己找食物！還是挺好玩的，一起來看看吧！

文中示例代碼介紹的非常詳細，具有一定的參考價值,感興趣的小伙伴們可以參考一下！

項目實現要求：

1.學過C語言

2.熟悉C語言數組

3.熟悉結構體

4.按鍵交互 程序：1.按鍵交互 2.鼠標交互

5.創建圖形窗口

6.基本繪圖

但是這些在我們項目源碼里面都會有注釋，大家到時候學習的時候千萬不要忽略注釋，注釋可以更好地幫你理解代碼，尤其是C語言初學者。

本項目編譯環境：VS2019/VS2013；

插件：圖形庫插件easyX；

#define _CRT_SECURE_NO_WARNINGS#include #include #include #include     //報錯：安裝圖形庫插件#include #define MAX 100        //蛇最大節數/*  1.學過C語言  2.熟悉C語言數組  3.熟悉結構體  4.按鍵交互  程序：1.按鍵交互   2.鼠標交互  5.創建圖形窗口  6.基本繪圖*///1.把程序所要用的數據抽象出來typedef struct pointXY{  int x;  int y;}MYPOINT;HWND hwnd = NULL;
//蛇struct mySnake{  int num;  MYPOINT xy[MAX];  char postion;    //表示方向，標記}snake;
//食物struct myFood{  MYPOINT foodxy;  int flag;  int eatGrade;}food;
//把方向枚舉出來enum movPostion{right=1,left=2,down=3,up=4};//整個項目劃分//1.初始化蛇void initSnake(){  snake.xy[2].x = 0;  snake.xy[2].y = 0;
