    14 <p>Iterators provide an easy way of cycling through the elements of a singly

    15 linked list, using the post increment operator<codeph>++</codeph>. They avoid

    16 the need to access the inner detail of link objects and list headers.</p>

    17 <p>An iterator is an instance of the templated class <codeph>TSglQueIter&lt;class

    18 T&gt;</codeph>. The class provides the behaviour for moving through the elements

    19 of a specific list. An iterator maintains a pointer to the current element

    20 in the list. The current element can be any element in the list.</p>
