The simplest solution is to use std::vector, from the <vector> header.

E.g.

     std::vector<A>  myArray;

     myArray.push_back( A( 1 ) );
     //...

And that's what you should be doing anyway, as a beginner. Don't mess around 
with raw arrays. For that matter, don't add assembly language stubs either. ;-)
