How is iterator implemented in vector class?

vector<int> v;
vector<int>::iterator i = v.begin();

I know vector is a template class. And iterator is an object. And also iterator is not a static object.

Then why we are not accessing it through dot operator.

And what does vector class looks like. Is iterator a member of vector class?

I got the solution:

Iterator is defined in vector namespace and typedef inside vector class.

In easy words,

iterator is nested class inside vector class. It is a public member. Since it is not a data-member but a nested class, so we access it using the " :: " operator.
