c语言程序设计：贪吃蛇

63 阅读 0 评论 42 点赞

我是靠谱客的博主活力楼房，最近开发中收集的这篇文章主要介绍c语言程序设计：贪吃蛇，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

主要的功能：1.上下左右方向键移动。

2.撞墙或者自杀有不同提示。

3.有分数显示。

4.空格暂停。

注意事项：要在vs上运行，且要含easyx。

话不多说见代码：

#undef UNICODE
#undef _UNICODE//为了使用outtextxy函数
#define _CRT_SECURE_NO_WARNINGS//为了使用sprintf函数
#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
#include<time.h>//随机函数头文件
#include<graphics.h>//easyx里的头文件
