STL vector class

Hi, What is the best method to allow a (C++) function access to elements obtained from a vector using an vector::iterator? Below, the first call to Test(int *) in main() fails to compile, while the second call is fine; I just think it looks a little unsafe. Any comments? Thanks, Graham void Test(int *); void main() { vector<int> A; vector<int>::iterator Iter; for (Iter = A.begin(); Iter != A.end(); Iter++) { Test(Iter); // error C2664: ''Test'' : cannot convert parameter 1 from ''std::vector<_Ty>::iterator'' to ''int *'' Test(&(*Iter)); // OK. } }

I didn''t know Fruny''s template technique; that''s very interesting.

Look at the contents of the <algorithm> header. That''s how the STL works.
