C++版:
代码说明：
- main.cpp：实现了贪吃蛇游戏的核心逻辑，包括游戏初始化、界面绘制、用户输入处理、游戏状态更新等功能
- Makefile：提供项目编译配置，支持通过make命令编译生成可执行文件
- 游戏特性：经典的贪吃蛇玩法，支持WASD控制方向，X键退出游戏，实时显示得分，碰撞检测(边界和自身)

代码说明：
- snake_game.py：实现了完整的贪吃蛇游戏逻辑，包括蛇的移动、食物生成、碰撞检测、分数计算等功能
- requirements.txt：项目依赖配置文件，指定了pygame版本要求
- 游戏特性：支持方向键控制、自动边界循环、碰撞检测、实时分数显示、游戏结束提示和重新开始功能
- 界面设计：采用网格背景、不同颜色区分蛇头蛇身、清晰的UI提示和操作说明
