C++多文件写法轻松实现练手小游戏：贪吃蛇！

每天一个编程小项目，提升你的编程能力！ 这个是用C++语法和链表知识实现的哦！

游戏说明

这是一个传统的贪吃蛇游戏，基于链表实现

按键说明

方向控制：↑↓←→ 或者 Q(逆时针)，R(顺时针)

速度：按下 space 加速，‘[’ 减速，‘]’ 加速 

食物：小键盘 + 增加食物，小键盘 - 减少食物 

其他：非小键盘数字键 9、0 可以调整帧率，小键盘 * 可以切换贪吃蛇模式，F1 帮助，F11 截屏

状态栏说明

生命状态：贪吃蛇是否存活，由于没有设置死亡，所以只有存活和濒死两种状态

等级：每吃 10 个食物升一级

分数：每个食物 10 分

速度：默认速度 0 ，可以调节，最快 10，最慢 -10

长度：贪吃蛇的节数（包括头）

食物数量：界面中的食物个数，最大 99 ，可以手动调整

蛇体模式：贪吃蛇的模式，分为正常、穿墙和无敌（穿墙的基础上可以穿过自己）

效果展示

简单了解游戏后我们就来试试吧！（直接上源码，大家可以看注释）
