vectors

i'm new to vectors and wanted some clearification to what this says. I'm assuming I understand, but I have been wrong before.

Code:

#include <vector>
vector<int> v;
vector<int>::iterator iter1 = v.begin();

instansiate a vecotor, assign that vectors iterator (counter) the address of the begining of the vecotor?

does every vector container have an iterator?

please forgive me if i'm way off, but this is my first time even looking at a vector.

does every vector container have an iterator?

Yep, several. All the STL containers have at least two iterators: a regular iterator like in your code, which is read/write and a const interator which is read only:

vector<int>::const_iterator
