神山で伝える神言語！15歳のための特別講座「Love C」in まるごと高専！

春といえば、

徳島、神山まるごと高専。

今年も新一年生にC言語を好きになってもらうべく、

特別講座「LoveC」でC言語を伝道、C言家(Cげんが)yrm。

夜は寮をジャックして全学生対象に特別講座「C言語でゲームづくり講座」。

宣伝ディスプレイありがとう！

vim好きがいるという会場のため、急遽vimで講座、さすが高専！

C言語はロボットやゲーム作り、OSやプログラミング言語作りとなんでもこなせる神言語。

敵が動くと避けゲーとして成立するかも？みんなも改造して遊んでみてね！

C言語用ゲームライブラリ「raylib」はこちら、ありがとうraysan5。

私服が同じ学生発見、もしやC言家！？

今年も楽しい会をありがとう、C言語、楽しんでね！
