Well your C book finally arrived down here in the antipodes:-) And I'm enjoying going through it a lot. It is helping to clarify some mis-conceptions that I had.
On page 146, the first line in fact, you have a signifier %lu but the downloaded code has %llu. Is this a minor errata or am I seeing double??
I checked the book errata but it's not there.
Thanks again for a great book.
Cheers from Oz.
