variable number of variables in C++
<p>Is it possible to make variable number of variables?  For instance, say I want to declare some unknown number of integers, is there a way to have the code automatically declare</p>

<pre><code>int n1;
int n2;
.
.
.
int nx;
</code></pre>

<p>where x is the final number of variables required.</p>

<p>A potential application requiring this would be reading a .csv file with unknown number of rows and columns.  Right now, the only way I can think to do this without variable number of variables is either a 2D vector, or coding in more columns than possibly can be in any input file the program receives</p>
