在c语言之家看到一篇代码，“五彩贪吃蛇”
效果也很不错，借此帖转帖一下。

程序代码：
五彩贪吃蛇 C源代码  原创  作者：Marlio Sky
Hello!


     好久没来C语言之家了, 由于最近工作太忙了, 我自己的空余时间太少, 个人的PROJECT就没法进行下去, 这个代码是我在最近一个星期内才完成的.


     首先我个人先介绍一下, 我是一个PC机游戏的开发爱好者. 我的这个游戏代码其实是应该用VC++6.0 加 Direct X 9.0 来完成的, 但是, 由于VC太复杂, DIRECT也有点难, 我个人正在学习中, 我个人知道只有这样才能迎合MICRO SOFT的PC开发平台. 


     Turbo C 2.0 的开发平台虽然说有些过时, 但是对于锻炼一些'C的技巧'和'项目的思路'还是很有帮助的! 在这个代码中, 我主要引用了面向对象的思路, 成员数据, 成员方法, 事件 ... 好了, 看一下代码吧!
