title: Find size of double * array C++
body: <p>If I have declared a <code>double *positions[2]</code> array, is there a way of finding the actual size of the <code>double *positions[2]</code> array?</p>
  
  <p>Is there like a <code>sizeof</code> function to find the size?</p>
  
  <p>I have tried an example, and it does not return the size as <code>4</code></p>
