<h3>Prototype</h3>
<pre>
template&lt;class <A href="InputIterator.html">InputIterator</A>, class <A href="EqualityComparable.html">EqualityComparable</A>&gt;
InputIterator find(InputIterator first, InputIterator last,
                   const EqualityComparable&amp; value);
</pre>                   
<h3>Description</h3>
Returns the first iterator <tt>i</tt> in the range <tt>[first, last)</tt> such that
<tt>*i == value</tt>.  Returns <tt>last</tt> if no such iterator exists.
<h3>Definition</h3>
Defined in the standard header <A href="algorithm">algorithm</A>, and in the nonstandard
backward-compatibility header <A href="algo.h">algo.h</A>.
<h3>Requirements on types</h3>
<UL>
<LI>
EqualityComparable is a model of <A href="EqualityComparable.html">EqualityComparable</A>.
<LI>
InputIterator is a model of <A href="InputIterator.html">InputIterator</A>.
<LI>
Equality is defined between objects of type EqualityComparable and
   objects of InputIterator's value type.
</UL>
<h3>Preconditions</h3>
<UL>
<LI>
<tt>[first, last)</tt> is a valid range.
</UL>
<h3>Complexity</h3>
Linear: at most <tt>last - first</tt> comparisons for equality.
<h3>Example</h3>
<pre>
<A href="List.html">list</A>&lt;int&gt; L;
L.push_back(3);
L.push_back(1);
L.push_back(7);

<A href="List.html">list</A>&lt;int&gt;::iterator result = find(L.begin(), L.end(), 7);
assert(result == L.end() || *result == 7);
</pre>
