how the iterator in c++ could be printed?

Question

Suppose, I have declared a vector in C++ like this:

vector<int>numbers = {4,5,3,2,5,42}; 

I can iterate it through the following code:

for (vector<int>::iterator it = numbers.begin(); it!=numbers.end(); it++){     // code goes here } 

Now, I would talk about coding in the block of for loop.

I can access and change any value using this iterator. say, I want to increase every value by 10 and the print. So, the code would be:

*it+=10; cout << *it << endl; 

I can print the address of both iterator and elements that are being iterated.

Address of iterator can be printed by:

cout << &it << endl; 

Address of iterated elements can be printed by:

cout << &(*it) << endl; 

But why the iterator itself could not printed by doing the following?

cout << it <<endl; 

At first I thought the convention came from JAVA considering the security purpose. But if it is, then why I could print it's address?

However, Is there any other way to do this? If not, why?
