<p>
A Forward Iterator is an <a href="./Input_Iterator.html">Input Iterator</a> that guarantees a linear traversal over the sequence. 
<p>
<h3>Refinement of</h3>

<a href="./Input_Iterator.html">Input Iterator</a>
<p>
<p>
<h3>Valid expressions</h3>
<p>
Forward Iterator does not define any new expressions beyond those defined in <a href="./Input_Iterator.html">Input Iterator</a>. However, some of the restrictions described in <a href="./Input_Iterator.html">Input Iterator</a> are relaxed.

<tr><td><code>typename i::next</code></td><td>A model of <a href="./Forward_Iterator.html">Forward Iterator</a> </td></tr>
</table>
<p>
<h3>Invariants</h3>
<p>
For any forward iterators i and j the following invariants always hold: 
<ul>
<li>if <code>i</code> and <code>j</code> are dereferenceable and <code>i</code> is identical to <code>j</code>, then <code>i::next</code> is identical to <code>j::next</code>.
</ul>
