In C++, 0 can be used instead of NULL everywhere except inside sizeof and
varargs argument lists.

But what is _preferred_, depends on your and your co-developers' habits.

People who also program in C prefer NULL because NULL does not have the
pitfalls with argument passing (that Simon mentioned) and in sizeof.

People who also program in Java or C# prefer NULL because in these languages
there is a strict distinction between pointers and integral values.
