私は長い間プロシージャルに取り組んできましたが、独自のクラスを作成したことはありません。独自の機能を作成しましたが、オブジェクトは作成しませんでした。クラスは私にとって非常に紛らわしいので、今は自分のコードで迷っています。物事をより簡単かつ効率的にする方法がわかりません。ここでのコーディング方法に基づいて、誰かが私が間違っていることの正しい方向に私を向けることができますか?
前の例に取り組んで、私は箱とそれに入れるいくつかのものを作っています。本。本は箱に入れるときの立体的な並べ方が違うので、どのように並べて入れるかで、何冊入るか決めたいです。LimitDeterminer は、それらがすべて同じ方向に配置されている場合に適合する数を決定し、既にそこにあるものと比較します。ブリーフィングだけで、コードは完全ではありません。私はイライラして混乱しているため、間違いを修正するためにここに来ました。また、関数にオブジェクトを常に指定する必要があるため、何か間違っていると思います...
ありがとう
