Message-ID: <5734@mcvax.UUCP> Date: Wed, 14-Mar-84 07:57:16 EST Article-I.D.: mcvax.5734 Posted: Wed Mar 14 07:57:16 1984 Date-Received: Thu, 15-Mar-84 07:15:33 EST Organization: CWI, Amsterdam Lines: 17 I'd like to hear the opinion of the net on the following (MAIL please; I'll summarize): The K&R book says that chars are widened to ints before anything is done to them (except when used as lvalue, I think). Does this mean that the following code is portable, even to the weirdest machines? foo(c) char c; { ... } bar(i) int i; { ... } main() { foo(100); bar(' '); } (Please, no guesses -- I can GUESS it's right myself.)
