If you were creating C code today and could use a C23 compiler, would
you use nullptr instead of NULL?

 
In greenfield projects under my dictatorship, I use 0, as in:
 
   char *p = 0;
 
I was still 20 something when I (easily) wrapped my head around the 0
null pointer constant, and have not had any problems with it.
Once I learned the standard-defined truth about null pointer constants,
and their relationship to the NULL macro, I dropped NULL like a hot
potato, and didn't look back (except when working in code bases that use
NULL).

We also used 0 as "universal" pointer value regularly without problems.

One practical advantage of adding a named entity (with a value of 0)
was to easily grep (find) appearances of this value in source code.
