Hi Alan,
Actually, "const char *" and "char const *" are absolutely equivalent in
all regards, both in C and C++.
I think you meant the difference between "const char *" and "char * const".
For exactly this reason (the confusion over 3 notations, 2 of which are
the same), I propose that we stick only to "const char *" and "char * const",
and don't use "char const *".
