Answer 1

here it is, obtaining a reference to the coresponding pointer of an iterator use :

example:

string my_str= "hello world";

string::iterator it(my_str.begin());

char* pointer_inside_buffer=&(*it); //<--

[notice operator * returns a reference so doing & on a reference will give you the address].
