Using header <new>

[Jonas Cord]

Hi, is it necessary to #include the standard header <new> in standard
C++ when using dynamic memory management? Deitel & Deitel state that it
is, but I have hardly ever seen it used.
Thanks

The answers is yes & no. If you take at look at the standard (3.7.3 ISO
14882:2003(E)) you'll find that a program using new or delete is well formed
without including the header <new>. However, refering to std::bad_alloc and
std::size_t is ill formed unless the name was introduced by including the
appropriate header file.

<new> contains:

.. class bad_alloc
.. set_new_handler ()
.. new (nothrow)

and several already global functions. If
you don't use none of these three features,
you don't need to include <new>.
