== Expressions ==

The Standard C++ syntax for a non-placement <code>new</code> expression is<ref name=Lischner2003 />

:<code>new</code> ''new-type-id'' ( ''optional-initializer-expression-list'' )</code>

The placement syntax adds an expression list immediately after the <code>new</code> keyword. This expression list is the placement. It can contain any number of expressions.<ref name=Lischner2003 /><ref name=Lippman1997 /><ref name=Loudon2003 />

:<code>new</code> ( ''expression-list'' ) ''new-type-id'' ( ''optional-initializer-expression-list'' )</code>

There is no placement delete expression.<ref name=SolterKleper2005 />

Line 91:

{ return here ; }

</source>

In your case, using this is not required as an int is [[Plain old data structure|POD]], it has a trivial constructor. If you want to use it, you could use it this way:<source lang="cpp" enclose=div>
