Chuckling at the memory of a professor railing against the just-adopted C95 and preaching K&R. He lost his shit again at C99. I used 'and' once in an assignment and I thought he was going to have a stroke.
He only taught C because the CS department decided that FORTRAN77 wasn't marketable anymore. I still had to learn it in the 1xx classes because tenure means you can teach anything you want, regardless of the class name.
