const CharT* c_str() const;
Restituisce un puntatore a una terminazione null array di caratteri con i dati equivalenti a quelli memorizzati nella stringa. Il puntatore è tale che l'intervallo [c_str(); c_str() + size()] è valido e valori in esso corrispondono ai valori memorizzati nella stringa con un carattere nullo aggiuntivo dopo l'ultima posizione.
Original:
Returns a pointer to a null-terminated character array with data equivalent to those stored in the string. The pointer is such that the range [c_str(); c_str() + size()] is valid and the values in it correspond to the values stored in the string with an additional null character after the last position.
