[line-eater bait, included because] [2.11news wants some extra lines anyway] In article <5230@mimsy.UUCP>, chris@mimsy.UUCP (Chris Torek) writes: >> Guy hardly needs defending, but it may sound better coming from two >> people: >> /* this code is not portable */ >> int a,b, *ptr; >> ptr = &a; >> ptr++; >> /* ptr now points to b */ This code works especially well if your optimizing compiler puts b in a register. Even the proverbial lament "but it worked on my *VAX*" may not apply here. -- # Bill Stewart, AT&T Bell Labs 2G-202, Holmdel NJ 1-201-949-0705 ihnp4!ho95c!wcs
