    Le modle de classe basic_string stocke et manipule des squences de char ou objets similaires, qui ne sont pas des tableaux de types triviaux de disposition-standard. La classe ne dpend ni du type de caractre, ni de la nature des oprations sur ce type. Les dfinitions des oprations sont fournies par le paramtre de modle Traits - une spcialisation de std::char_traits ou une classe de traits compatibles. Traits::char_type et CharT doivent dnommer le mme type; dans le cas contraire le programme est malform.

    Les lments d'un basic_string sont stocks de manire contigu, ce qui signifie que pour une basic_string s, &*(s.begin() + n) == &*s.begin() + n pour tout n dans [0, s.size()), ou, de manire quivalente, un pointeur vers s[0] peut tre pass des fonctions que attendent un pointeur vers le premier lment d'un tableau charT[].
