Which of the following could you use to declare the iterator p? Why?
Suppose you want to run code that involves the loop
```
//Assume vector v and iterator p has been defined and
//given appropriate values
for (p = v.begin(); p != v.end(); p++)
cout << *p << “ “;
```
```
std::vector
std::vector
```
You could use either, but you probably should use const_iterator. In the loop, the iterator p is used to fetch from the container. There is no code that would change the container’s contents.
