Ummm, no.  One declares and initializes a pointer, the other declares and
initializes an array of characters.  For a discussion see K&R, second
edition, pp. 104 & 219.  In particular, fred[0] = 'h' or *fred = 'h' is
legal for the second declaration but not for the first (according to ANSI),
while fred = "Goodbye" is legal for the first but not for the second.

The original posting in this thread referred to initialization of an
_automatic_ array.  This was forbidden by the original K&R but is permitted
by ANSI C.  See K&R, second edition, p. 219.
