每天一個程式設計小項目，提升你的程式設計能力！這個是用C++文法和連結清單知識實作的哦！

遊戲說明

這是一個傳統的貪吃蛇遊戲，基于連結清單實作

按鍵說明

方向控制：↑↓←→ 或者 Q(逆時針)，R(順時針)

速度：按下 space 加速，‘[’ 減速，‘]’ 加速

食物：小鍵盤 + 增加食物，小鍵盤 - 減少食物

其他：非小鍵盤數字鍵 9、0 可以調整幀率，小鍵盤 * 可以切換貪吃蛇模式，F1 幫助，F11 截屏

狀态欄說明

生命狀态：貪吃蛇是否存活，由于沒有設定死亡，是以隻有存活和瀕死兩種狀态

等級：每次 10 個食物升一級

分數：每個食物 10 分

速度：預設速度 0 ，可以調節，最快 10，最慢 -10

長度：貪吃蛇的節數（包括頭）

食物數量：界面中的食物個數，最大 99 ，可以手動調整

蛇體模式：貪吃蛇的模式，分為正常、穿牆和無敵（穿牆的基礎上可以穿過自己）

效果展示

簡單了解遊戲後我們就來試試吧！（直接上源碼，大家可以看注釋）
