Os elementos de um basic_string são armazenados de forma contígua, ou seja, para um basic_string s, &*(s.begin() + n) == &*s.begin() + n para qualquer n em [0, s.size()), ou, de modo equivalente, um ponteiro para s[0] podem ser passados ​​para funções que esperam um ponteiro para o primeiro elemento de uma matriz charT[]. (a partir do 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. (a partir do C++ 11)
