How to call base class copy constructor from a derived class copy constructor?

Question

Just like in the title, how do you call a base class copy constructor from a derived class copy constructor?

The more important Q is why do you want to do this? – Alok Save Jun 26 '13 at 04:11 — Alok Save, Jun 26 '13 at 04:11

You can specify base initialization in the initialization list:

Derived:: Derived( const Derived& other ): Base( other )
{ /* ... */ }

Derived( Derived const& d )
: Base(d)
/* some member initialization */
{
  /* ... */
}

Am I missing something?
