"char *s;" defines a pointer to char.  At runtime, it may or may not
point to the initial element of an array object.  (And for most
purposes, a char object is treated as 1-element array of char.)

It may be a pointer to a string at run time, depending on what it
currently points to.

"s" can point to *the initial element of* an array of chars.  if that
array contains a string, then (the value of) s is by definition a
pointer to a string.
