Yes, C++ is a very portable general purpose language that runs on
platforms ranging from super computers to embedded devices. Many of
these platforms and applications which run on them do not require
everything all the time, so it doesn't make sense to stuff GUI,
networking, threading, etc. all into the standard library.

Re: Standard C++ Library

So there are 3 types of library / header in C++?

CRT (C runtime library)
Standard C++ Library
Platform SDK for Visual C++

where CRT is low level code like doing all the bit and bytes
where Platform SDK is high level code doing all those Web Service,
Security, Message Queue, UI / GUI, COM, HTTP / networking stuff?

any other must have / used alot kind of library for C++ that
programmer use alot besides the above 3 library?

No, there's the C++ standard library, which includes the C standard library.

Anything else is platform specific.

There are several cross-platform libraries that are in widespread use,
boot being one.

Where is this HashMap container in the Standard C++ Library? Poor "Bo
Persson" can't find it. Something he needs to speed up the word
counting benchmark, which for now is more than 2 times slower.

To the OP -

Ian meant "... widespread use, /boost/ being one." (cf. www.boost.org)

Where is the HashMap container in c++ standard library?

Got it this time?

It makes a big difference in speed if you use std::map vs HashMap in
some situations. So where is the HashMap?

Two questions: Why did you troll this thread? Have you ever written
a piece of production software in your life?

That's obvious, as you seem to be capable of toy programs only and
don't seem to understand the complexities of developing robust
software that performs well.

Why don't you include Python in your benchmarks? I'm sure Java and C+
+ would beat the fool out of it, and yet it is used by Google,
YouTube, NASA, Industrial Light and Magic, and many other large
organizations to real production work. Just the same, you could burst
in their front doors waving your arms like a maniac telling them that
it is too slow. Maybe they'd listen to you. Maybe they'd call
security. I think it's worth a shot.

Why don't you? Let me see a Python and Perl version.

I never claimed speed is everything, but that's the topic we have been
discussing, for fun obviously.

now that's funny :)

How come you have FIDE in your email?

So which is it: anything else is platform specific, or there are
several cross-platform libraries? And I'm pretty sure you mean
Boost, not boot. (Not that that's the only cross-platform
library around.)
