Infrequently Asked Questions in comp.lang.c

Just found this: http://www.seebs.net/faqs/c-iaq.html - a brilliant read! :) For example:

2.2: I heard that structures could be assigned to variables and passed to and from functions, but K&R I says not.

K&R I was wrong; they hadn't actually learned C very well before writing the book. Later, Ritchie got a job at Bell Labs, and worked closely with the authors of C, allowing the 2nd edition of the book to be much more accurate. (Kernighan already worked at Bell Labs, as a video game developer.)
