Die Elemente eines basic_string zusammenhängend gespeichert, dh für eine basic_string s, &*(s.begin()+ n)==&*s.begin()+ n für jedes n im [0, s.size()), oder äquivalent, einen Zeiger auf s[0] können mit Funktionen, die einen Zeiger erwarten auf das erste Element eines charT[] Array weitergeleitet werden. (seit 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. (seit C++11)
