I'm a C++ newbie and wondered whether C or C++ have an 'arbitrary

I am currently developing maths programs in PHP, and PHP has a
'large number' type facility, but have been considering a switch to C++ as
its faster.
Just search the web for 'Big Integer' or 'Big Number' Libraries.
There are plenty available.
Compared to Java (can't talk about PHP) the standard facilities of
C++ are 'poor'. C++ has only the bare minimum for safe programming.
Everything else is non standard.
It's not clear to me why nobody has written a large class
library for C++, so that 'out of the box' it will have as much
functionality as PHP or Java.
Such a library would mean you could pick up your C++ compiler
and write a web site just as easily as you can in PHP now,
for example.
Of course, such a library would be bloaty, but that is a
less important concern than speedy development time, for
many people (as evinced by the popularity of PHP).
PS. I have a question about Google groups formatting, since
I read and write via it I can't answer this question myself:
does it re-word-wrap the text I have quoted above? Or does
it look like long lines interspersed with one-word lines where
the last word has been wrapped around due to increased quote
indent?
