I don't and never have had a problem calling either K&R I I have both)
the reference, it is after all, written by the authors of the C
language. If it suffers in any regard, it can be a little too concise,
an occassional example to illustrate a point would be most welcome.

That has never been a problem once you understand that a pointer, even to
a 3 or 4 dimmensional array of data, is nothing more, nor less, than the
address in memory of the first element of that array. ALL other offsets
to other elements in that array are calculated, sometimes in the code
issued by the compiler, or occasionally in issueing the code to
calculate it on the fly. Not often done as its a huge speed hit when it
does that.
