the thing is i have list&lt;list&lt;string&gt; &gt; examples. <br>
<br>
template &lt;typename T,<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; template &lt;typename ELEM,typename = std::allocator&lt;ELEM&gt; &gt;<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; class CONT<br>
&gt;<br>
void testFunc(const CONT&lt;CONT&lt;T&gt; &gt;&amp; container)<br>
{<br>
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
std::find_if(container.begin(), container.end(), <br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ( <br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; bind(&amp;CONT&lt;T&gt;::back(), _1) == var(targetValue)<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; )<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; );<br>
}<br>
<br>
std::vector&lt;std::vector&lt;std::string&gt; &gt; examples;<br>
<br>
testFunc&lt;std::string, std::vector&gt;(examples);<br>
<br>
since list don't have indexing i want to see if the last item in the container is. .<br>
<br>
However i get this error...<br>
<br>
cannot call member function `typename _Alloc::reference
std::vector&lt;_Tp, _Alloc&gt;::back() [with _Tp = std::string, _Alloc
= std::allocator&lt;std::string&gt;]' without object <br>
