界: Code Quality

コードの質が低いと、予測できない動作につながります。ユーザーの視点には、それがしばしば使い勝手の悪さとなって現れます。攻撃者にとっては、予期せぬ方法でシステムにストレスを与える機会となります。

Code Correctness: Arithmetic Operation on Boolean

Abstract

プログラムが算術演算子をブール値について使用する場合、プログラマが念頭に置いている状況を達成できない場合があります。

Explanation

ブール値に対する算術演算子の動作は、整数値に対する動作とは異なるため、予期せぬ動作を引き起こす場合があります。
