<div class="level2">
<p>
Syntax:
</p>
<pre class="c code c++" style="font-family:monospace;"> <span class="co2">#include <string></span>
size_type find_last_not_of<span class="br0">(</span> <span class="kw4">const</span> string<span class="sy0">&</span> str<span class="sy0">,</span> size_type index <span class="sy0">=</span> npos <span class="br0">)</span> <span class="kw4">const</span><span class="sy0">;</span>

size_type find_last_not_of<span class="br0">(</span> <span class="kw4">const</span> Char<span class="sy0">*</span> str<span class="sy0">,</span> size_type index<span class="sy0">,</span> size_type num <span class="br0">)</span> <span class="kw4">const</span><span class="sy0">;</span>

<p>
The find_last_not_of() function either:
</p>
<ul>
<li class="level1"><div class="li"> returns the index of the last character within the current string that does not match any character in str, doing a reverse search from index, string::npos if nothing is found,</div>
</li>
<li class="level1"><div class="li"> returns the index of the last character within the current string that does not match any of the first num characters in str, doing a reverse search from index, string::npos if nothing is found,</div>
</li>
<li class="level1"><div class="li"> returns the index of the last character within the current string that does not match ch in the current string, doing a reverse search from index, string::npos if nothing is found.</div>
</li>
</ul>
<p>
For example, the following code searches for the last non-lower-case character
in a mixed string of characters:
</p>
<pre class="c code c++" style="font-family:monospace;"> <span class="kw4">string</span> lower_case <span class="sy0">=</span> <span class="st0">"abcdefghijklmnopqrstuvwxyz"</span><span class="sy0">;</span>
<span class="kw4">string</span> str <span class="sy0">=</span> <span class="st0">"abcdefgABCDEFGhijklmnop"</span><span class="sy0">;</span>
<a href="http://www.opengroup.org/onlinepubs/009695399/functions/cout.html"><span class="kw3">cout</span></a> <span class="sy0"><<</span> <span class="st0">"last non-lower-case letter in str at: "</span> <span class="sy0"><<</span> str.<span class="me1">find_last_not_of</span><span class="br0">(</span>lower_case<span class="br0">)</span> <span class="sy0"><<</span> endl<span class="sy0">;</span></pre>
<p>
This code displays the following output:
</p>
<pre class="code">
last non-lower-case letter in str at: 13</pre>
