纯C语⾔编写贪吃蛇（附源码，⽆EasyX、MFC）
⼤⼀下学期，我所选的C语⾔⼯程实践是写⼀个贪吃蛇游戏。那⼏天真的挺肝的，完成本专业的答辩之后就没怎么动过这程序了。那时候写的贪吃蛇，还有⼀个栈溢出的问题没有解决，是因为当时所学知识有限，还没想到较好的解决⽅法。现在⼤⼆上学期，在上了好⼏节数据结构之后，对栈有了⼀定的了解，随着对栈的学习，我想出了解决我写的贪吃蛇栈溢出的办法。其实是前两天刚刚有这个想法，刚刚才测试并实现了，办法可⾏。现在我加⼊了计算机学院的创新开放实验室，打算做的⼀个项⽬是⼩程序。以后想记录⼀下我的开发过程和⼀些经历，⼜刚刚完善好贪吃蛇的代码，就简单记录⼀下吧。
因为代码⽐较长，先把参考资料写⼀下，想⾃⼰⼿写⼀遍的建议先看参考资料，再看这⾥的代码
