Because passing the city by copy is way too expensive and won't destroy the original city anyway.

Many years ago, this joke appeared in an April issue of the Communications of the ACM (before the Cray 3 actually existed): "Have you heard about the new Cray 3? It's so fast it can execute an infinite loop in about two minutes.&q

It's possible they rejected it simply because it didn't review the product. A review that expresses an opinion about the product and also mentions that other reviewers are being paid might be accepted.

In C, for example, "if (foo != true)" is not necessarily equivalent to "if (!foo)" -- but the latter very probably reflects the author's intent more accurately. For example, an int with the value 42 is logically a &

An administrator account, in this context, is one that's a member of the "sudo" group. It's perfectly ordinary for more than one account to be a member of that group.

Is that true? In the past (long enough ago that using md5 almost made sense), I used a combination of md5 and sha1 to verify file integrity. Both checksums had to match or the file was rejected. It seems obvious that that's at least

The article says 1886, but the caption on the video and Wikipedia both say 1896, which seems much more plausible.

And the transition from Julian to Gregorian just changed the leap year rules. It didn't change the fact that there's no year 0. The 1st Century began in the year 1. I don't believe anything in ISO 8601 refers to the century s

Speaking even more pedantically, a new decade is starting right now ... and here comes another one. The 2020s start 2020-01-01 (just as the century called "the 1900s" started 1900-01-01). The 21st century started 2001-01-01. The 2

We had a bug tracking system that malfunctioned starting at (time_t)1000000000 (3 days before 9/11). Apparently it converted the time_t value to a string and truncated it to 9 characters. Its concept of the current time jumped back to

Making time_t unsigned would break the ability to refer to times before 1970. Existing code that deals with 32-bit timestamps almost universally assumes that (time_t)0 is 1970-01-01 00:00:00 UTC. Updating that code to guess a different epoc

Is "x<-3" an assignment to x or a comparison of x to -3? The same problem led early C (pre-K&R1) to change its compound assignment operators from "=op" to "op=". In early C, "x = -3" assigned t

A particular implementation of printf used that technique. There probably weren't a whole lot of different implementations at the time, but it's not part of the C specification. <varargs.h> was a pre-Standard header that pro

Sort of. ANSI introduced prototypes, but old-style function declarations and definitions, though they were declared obsolescent, remained valid (i.e., any conforming C compiler is still required to support them). As of the 2011 standard, th

There are published rationales for C90 and C99, but not for C11. (Actually the original rationale is for ANSI C89, which differs from ISO C90 mostly in the way the sections are numbered.) C89: https://www.lysator.liu.se/c&#x

Good point. "void" does not appear in K&R1 (1978), and there was no definitive manual for the language between that and the ANSI standard, but it did start appearing in implementations. Still, I'm not aware of any impleme
