I was reading the list reference on cplusplus.com and I found something: it says when I call clear or erase, for each element it removes it calls its destructor. so if I have
Object *o=new Object();
list<Object *> objects;
objects.insert(o);
objects.clear();
will o be deleted? or does it simply erase the pointer in the list? Because I don't want the list deleting my objects if it's not creating them too.

Standard library containers won't call delete on pointers they hold.

The destructor of the object stored in the vector will be called. Your vector stores pointers, and pointers don't have empty an destructor (or no destructor at all, if you want). It doesn't do anything with the object being pointed to, because the vector cannot know what has to be done.

Pointer variables don't have destructors. If you want that behavior, use a smart pointer like boost::shared_ptr.
