Les éléments d'un basic_string sont stockés de manière contiguë, qui est, pour une basic_string s, &*(s.begin() + n) == &*s.begin() + n pour tout n dans [0, s.size()), ou, de manière équivalente, un pointeur vers s[0] peuvent être transmises à des fonctions que peut attendre un pointeur vers le premier élément d'un tableau charT[]. (depuis C++11)

Original:

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. (depuis C++11)
