This time I am going to demonstrate a very serious problem with the

The algorithms used by C, C++, and D are BETTER than the Java
versions! What the heck? In some cases Java version is so bad that
it's 10 times slower.

Let's start over again. We go through the list one by one.

You have this version of Java for fannkuch

http://shootout.alioth.debian.org/gp4/benchmark.php?test=fannkuch&lang=java&id=2

I wrote a different version (algorithm used by Heiner Marxen)

http://pastebin.com/f41c2ef6f

When n = 11

0m10.165s -client (old version)
0m6.064s -client (this new version)

4 seconds faster...

Let's compare it now with C++ version

I wrote one function which is used to count comment and code lines and
it works as it should be, but when compiling I get warning (i686-apple-
darwin9-g++-4.0.1):

pirma.cpp: In function ‘int CheckLine(const std::string&, int&)’:
pirma.cpp:112: warning: control reaches end of non-void function

So, it looks like somehow it still can get to the end of the function,
the problem is that I can not figure out that I could have missed.
This way I added return UNDEFINED at the end of the function, but I
still would like to get the answer what I could have missed.

The whole function has only new local variables and if structure:
int CheckLine(const string &line, int &status) {
string::size_type startPos;
bool emptyStatus = true;

I got a question which was asked by my M.Tech compsci cousin.....
Which is the easiest way to divide by 2 from the OS perspective???

Is it now common practice to use conditional statements like

if (0 == i)
if (-1 == i)
if (true == i)
if (5 == i)

over the more traditional statements like

if (i == 0)
if (i == -1)
if (i == true)
if (i == 5)

for all types of 'i' (PODs and classes)?

Good morning, I'm Filippo Battaglia. We're porting Apache STDCXX
under Nanodesktop. We are trying to make nd compatible also with
C++ and not only with C.

Unfortunately, we're finding different technical troubles in the
compilation.

So, can anyone of the developers tell with me ? So, I can solve
the troubles step by step and I can obtain a working version of
the library.

Your library is critical for Visilab Research, because, if it works,
we can port Tesseract under nd and Blind Assistant will be
completed.

PLEASE, anyone can help me ? It's very, very important.

Thanks in advance
Filippo Battaglia

Welcome to comp.lang.c++! Read this first.

This post is intended to give the new reader an introduction to reading
and posting in this newsgroup. We respectfully request that you read
all the way through this post, as it helps make for a more pleasant
and useful group for everyone.

First of all, please keep in mind that comp.lang.c++ is a group for discussion
of general issues of the C++ programming language, as defined by the ANSI/ISO
language standard. If you have a problem that is specific to a particular system
or compiler, you are much more likely to get complete and accurate answers in a
group that specializes in your platform. A listing of some newsgroups is given
at the end of this post.

The FAQ (Frequently Asked Question) list has a wealth of information for
both the new and veteran C++ programmer. No matter what your experience
level, you are encouraged to read the entire list, if only to familiarize
yourself with what answers are available to minimize redundant replies.
The comp.lang.c++ FAQ is available at http://www.parashift.com/c++-faq-lite/

If the FAQ list does not help, then many regular readers of this group
are happy to assist with problems of standard C++. We have only a few
requests that we ask be adhered to, for the benefit of all:
