An Introduction to Data Structures

Linked Lists

To move an iterator forward in the list, use the ++ operator.
```
pos++;
```
To move an iterator backward in the list, use the -- operator.
```
pos--;
```
You can find the value that is stored in the position with the * operator.
```
string value = *pos;
```
The value *pos represent the value that is stored in the list.
```
*pos = "Van Dyck, Vicki";
```
To insert another string before the iterator position, use the insert function.
```
staff.insert(pos, "Reindeer, Rudolph");
```
