Original:

The class template basic_string stores and manipulates sequences of char-like objects (that is, objects for which a specialization of std::char_traits or compatible traits class is provided).

Элементы basic_string хранятся непрерывно, то есть для basic_string s, &*(s.begin() + n) == &*s.begin() + n для любого п в [0, s.size()), или, что эквивалентно, указатель на s[0] могут быть переданы функции, которые ожидают указатель на первый элемент массива charT[]. (начиная с 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. (начиная с C++11)
