Defined in header <locale>
protected: ~ctype();
std::ctypeファセットを破棄します。このデストラクタは(基底クラス仮想デストラクタであることに起因する)保護と仮想されています。このファセットを実装最後std::ctypeオブジェクトがスコープまたはユーザ定義のクラスがstd::locale由来や公共デストラクタを実装されている場合は外に出るときは、型std::ctypeのオブジェクトは、ほとんどのファセットのように、破壊できるだけで.
Original:
Destructs a std::ctype facet. This destructor is protected and virtual (due to 基底クラス destructor being virtual). An object of type std::ctype, like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope or if a user-defined class is derived from std::ctype and implements a public destructor.
