Your compiler will reject that code (even without the typo). set::insert
(at least the single-argument version) doesn't return an iterator, it
returns a pair<iterator,bool>. The bool in the pair indicates whether
the insertion was successful. If it's true, then the iterator points to
the newly inserted element; if it's false, it means an identical element
was already present in the set, and the iterator points to that element.
("Identical" defined in terms of the set's comparison parameter.)

Yes, that will do as you expect: the returned iterator points to the
newly inserted element.

For containers that allow duplicate elements (vector, deque, list,
multiset, and multimap), the insert(object) method returns an iterator
pointing to the newly inserted element. For containers that don't allow
duplicate keys (set and map), it returns a pair<iterator,bool>, as
described above.

Hello all,
 I am using the vector and set sequences in the STL and can't seem to
find what iterator the insert function returns.
 set<int> links;
 // load set
 set<int>::interator currents = links.insert(5);
 does currents point to the element I just inserted?  how about
with vectors:  vector<int> pages;
       vector<int>::iterator currentv = pages.insert(pages.begin(), 5);
I am looking at the 12/96 draft and don't see anything that specific.
 John
