Hi All,
I want to perform some date calculations. Is there any standard class
in the C++ which will help me?
I want to perform operations like, difference between 2 date,
incrementaing the date etc.
I am working on SUSE 10 (LINUX kind of os). And using g++ and c++ for
comilations.
Thanks in advance.
Thanks & regards,
Prasad. 6 3428

The boost date_time library is currently being discussed for inclusion
in the next version of the C++ standard: http://www.boost.org/doc/html/date_time.html
To get it you will need to download and install the boost distro from http://www.boost.org

Boost keeps data on which of their libraries work with each compiler.
See the links from theRegression Tests heading for date_time at http://www.boost.org. e.g: http://tinyurl.com/nszzf

In addition to the boost suggestion (which is a good suggestion), here's
a date class with a cute syntax: http://home.twcny.rr.com/hinnant/cpp...rian_date.html
It allows a very intuitive and error-proof construction:
date d = may/19/2006;
Or if you want the 3rd Friday in May:
date d = 3*fri/may/2006;

No

If you want a lightweigth date class (and don't want to introduce the
complexity of Boost into your program) look for one of the freely
available date classes like zDate and the 'Killer Date class'.

Interesting and ingenious. But I think there might be an argument for
_not_ using the locale to determine the default output format, but
instead to use the unambiguous ISO standard format yyyy-mm-dd.
(http://www.cl.cam.ac.uk/~mgk25/iso-time.html)
There's no reason why it can't be more liberal in what it accepts for
input, and maybe add a locale-dependent user-formatted output function
as well.
The default "C" locale's format is unfortunately horribly ambiguous. You
may think 10/12/50 was in October, but I happen to know it was December,
and if you live in Thailand it won't happen until next year. 1950-12-10
is unambiguous, *and* as a bonus you can sort it lexicographically. Or if you want the 3rd Friday in May:
date d = 3*fri/may/2006;

Thanks. And agreed. I/O is its weak point. I basically just gave up
(punted). The C++ locale system and I don't get along very well.
