== '''C''' and '''C+''' languages ==
The C anc C++ examples don't really fit the task description (and it's not possible to do so, because C and C++ don't know a generic null object). What you can have is a null ''pointer'', which is a pointer which doesn't point to any object (and that is indeed what <code>NULL</code> is for). The closest to a null object in C++ would be an empty <code>boost::optional</code> from the boost library.

== Delphi vs. Pascal ==
The entries of [[Delphi]] and [[Pascal]] in this article should be exchanged, since Pascal is the language, Delphi is one implementation, (one among others)
And since the null-object is no Delphi-specific feature.
