Defined in header <string>
template<     class CharT,     class Traits = std::char_traits<CharT>,     class Allocator = std::allocator<CharT> > class basic_string;

クラステンプレートbasic_stringは、charのようなオブジェクト（std::char_traitsまたは互換性のある特性クラスの特殊化が提供されるオブジェクト）のシーケンスを格納し操作します.

basic_stringの要素は、連続して格納されます。つまりbasic_string sは、[0, s.size())の範囲の任意のnに対して&*(s.begin() + n) == &*s.begin() + nが成り立ち、または、同様にs[0]へのポインタをcharT[]配列の最初の要素へのポインタを受け取る関数に渡すことができます。 (C++11およびそれ以降)

一般的な文字の種類に対する、いくつかの特殊化が提供されています

Defined in header <string>
型	定義
std::string	std::basic_string<char>
std::wstring	std::basic_string<wchar_t>
std::u16string	std::basic_string<char16_t>
std::u32string	std::basic_string<char32_t>
