c++ - Remove item from std::list with only having access to the iterator -

std::list double linked list. doesn't mean should possible remove item list having access iterator?

maybe question wasn't clear enough.

#pragma once  #include <list>   typedef std::list<int> intlist ; typedef intlist::iterator intiterator;  class inthiddenlist { private:     intlist list; public:     intiterator addint(int x)     {         list.push_front(x);         return list.begin();     } };  int main() {     inthiddenlist a;      intiterator = a.addint(5);       // how go deleting 5 list using "it"? } 

yes, notionally it's possible. however, standard library not allow (it requires container , iterator erase).

however you're in luck: boost provides boost::instrusive (http://www.boost.org/doc/libs/1_54_0/doc/html/intrusive/list.html) capability want.
