0 is ambiguous
It has been a long time since my last entry. In fact, it was so long, that this condition has already been pointed out pushing me into finally writing something. Inspired by Adriaan de Groot's entry, I decided to write something about 0, NULL and upcoming nullptr.
I will try to be informative and explain what the whole buzz is about and then give my opinion about nullptr. Let us first inspect how a null pointer can be donated in C and C++.
