assistant: On (03 May 97) Benjamin L Mcgee wrote to Craig A Mckay...
Maybe, but maybe not.  There are quite a few ways to deal with any given
problem.  In this case, the input and output are almost incidental to
the real problems - reading input is pretty trivial, and writing the
output is even simpler.  The real problem here is finding the functions
in the text you read - trust me when I say that this is quite a complex
problem to deal with correctly.  Objects here are likely to include a
lexer, a parser and a symbol table.  These will doubtless use various
auxilary classes as well, but they're likely to be the main ones.
This is definitely true.
This is also true, though as you might expect, implementing your OO
design without an OO language is often somewhat clumsy.
I prefer bulletted lists myself, but they're harder to handle in ASCII.
Not necessarily.  Certainly when you deal with physical objects, they're
often modelled well by objects in your programs.  However, many objects
in programs are for things like data structures that have no physical
analogs at all.  Others are used for things be modelled in the program,
that have physical analogs, but ones that don't directly interact with
the program itself.
For the sake of clarity, many demo programs make a conscious attempt at
creating objects for which there are direct physical analogs. This is
(usually) more to help clarify ideas than because it's the only
possibility.

Hehehehe.  Jist gettin ma own back.  :)  There's an interesting mix of people
who contribute to this echo, most of which are well beyond my confident
knowledge of C/C++ -- particularly the current thread about compiler
optimisation.  I know three guys who wrote a small C compiler for a
articular
microcontroller, and they did a really tidy job of it.  A two-stage
compilation
(firstly converting to a temporary meta-C, then assembling).  It even
preserves
variable names, etc., so it's easy to debug the assembly.
Oops, I realise this is a tad off topic and Mr Mod will shout at me.
A question, then.  Has anyone in here done any concurrent programming in C++?
It was a subject I thoroughly enjoyed and I would really like to get involved
with when I finally get a job.  Let me know what you've used in terms of
solutions to the problems associated with concurrent programs.

Why fuzzy logic?  I mean, that's a reasonably complex system to apply to a

omething
like reinforcement learning would be overly intense.  What about a simple
heuristic based decision-making algorithm?  Or perhaps using something like
Means End Analysis.  Now I'm being pedantic...  that's the last of the guy's
worries!
Good advice, I'd say.  I think he'd find Pacman challenging enough.  I wrote
one in BASIC, and there were many issues even in that which were
time-consuming.
The main reason I butted in here, Cameron, was because I wondered if you had
done any of the 3D - 2D stuff you were speaking about...  I haven't and I've
hunted out a few books, but they all contain too much maths, and I can't seem

assistant: o

And what is an 'average' consumer machine?  Most likely a 486 or 586
machine.  Those two are at least 95% of the all the PCs used in the
world.  And then what is the 'average' consumer CPU in that 'average'
consumer machine?  Every different one will behave differently and
different pieces of code will be 'optimal'.
As I have a fairly typical low end 486 (a 486/66, 20megs and 128k L2
cache), it is indeed fairly safe to say I have a typical computer.  And
as I used DJGPP for my tests, it's also safe to say I used a typical
compiler.  And got very very different results than what you did.  Which
is the point.... low level optimizations are not reliable in their
benefit.
No, not a lie.  An error, yes.  -O3 adds automatic function inlining and
I was thinking it was basic loop unrolling.
egisters.
I checked my code.  I know what mine does and does not do.  And quite
obviously, it's different from yours.  Which is sort of the point.... It
makes it very very hard to optimize source for any particular compiler
or CPU.
I used a very typical DJGPP.  Widely available (discussion of DJGPP was
the source of this thread).  And it can certainly keep them in
registers.  The x86 has enough registers that it is able to keep the
only 3 variables in that piece of code in registers.
.......... Well, all compilers should "removes unused variables from
registers".  No optimizing compiler would assign an unused variable to a
register.
But as to what is and is not kept in registers depends on the compilers,
and on something as simple as that example I gave, the odds are very
very good that a compiler will be able to keep all three key variables
in registers.
