Los elementos de un basic_string se almacenan de forma contigua, es decir, para un basic_string s, &*(s.begin() + n) == &*s.begin() + n para cualquier n en [0, s.size()), o, de manera equivalente, un puntero a s[0] se puede pasar a funciones que esperan un puntero al primer elemento de una matriz charT[]. (desde 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. (desde C++11)
