basic_string 클래스 템플릿은 char 또는 이와 유사한 객체의 시퀀스를 저장하고 조작합니다. 이 클래스는 문자 자료형이나 그것의 연산에 관한 성질에 의존적이지 않습니다. 대신에 이러한 연산의 정의는 Traits 템플릿 매개변수로부터 주어지는데, 이는 특수화된 std::char_traits이거나 이와 호환되는 traits 클래스입니다.

The elements of a basic_string are stored contiguously, that is, for a basic_string s, &*(s.begin() + n) == &*s.begin() + n for any n in [0, s.size()), or, equivalently, a pointer to s[0] can be passed to functions that expect a pointer to the first element of a CharT[] array.

(since C++11)

공통 문자 타입을 위한 몇몇 자료형이 정의되어 있으며, 아래와 같습니다.

<string> 헤더에 정의되어 있음.
