Yeah, like K&R I, p. 111:
	
	"argv is a pointer to an array of pointers" *

I believe this is in Edition II, as well.

I think there is an excellent explanation for the confusion about arrays and
pointers:  the "base document" for C didn't always get it right.
I was hopelessly confused about pointers/arrays until I got Harbison & Steele's
tome.  I don't think it's a fault in the language, just in its original
explication.


* note to authors writing new C books:  "argv" is actually a
  "pointer to pointer to char", or, more descriptively, a "pointer to the
  first element of an array of pointers".
