1. MANAGEMENT SUMMARY

1.1 JTC1/SC22/WG21 STATEMENT OF SCOPE

Development and maintenance of ISO/IEC Standards related to the
programming language C++.

1.2. PROJECT REPORT

1.2.1. COMPLETED PROJECTS

JTC 1.22.32- Programming Language C++ - This project was delivered by the
publishing of ISO/IEC 14882:1998 (first standard) and :2003 (minor revision).

1.2.2. PROJECTS UNDERWAY

JTC 1.22.18015 Information Technology - Programming Languages Technical
Report on C++ Performance (Technical Report Type 3)

JTC 1.22.19768 Information Technology - Programming Languages Technical
Report of Type 2 on C++ Library Extensions (based on ISO/IEC 14882)

JTC 1.22.24733 Information Technology - Programming Languages Technical
Report of Type 2 on Extensions for the programming language C++ to support
decimal floating point arithmetic

JTC 1.22.24737 Information Technology - Programming Languages Technical
Report of Type 2 on C++ Library Extensions (based on ISO/IEC 14882)

JTC 1.22.32- Work has begun on the first major revision.

1.2.3. CANCELLED PROJECTS

None over this period.

1.2.4. COOPERATION and COMPETITION

Where appropriate, WG21 has established liaisons with other SC22 and SC22
liaison organizations' working groups. There is no direct competition with
any other current SC22 working group. Related work is being done in
SC22/WG14 (C) and Ecma TC39/TG5 (C++/CLI) with broad WG21 liaison to both
groups.


2. PERIOD REVIEW

2.1. MARKET REQUIREMENTS

ISO C++ remains a widely-used foundation technology, well-received in
the marketplace. WG21 is developing a revision of ISO 14882, and is
completing work on a Technical Report on C++ Library Extensions.

2.2. ACHIEVEMENTS

The technical work on JTC 1.22.18015 Information Technology Programming
Languages Technical Report on C++ Performance (Technical Report Type 3)
is complete and in DTR balloting.

2.3. RESOURCES

WG21 meets two times per year in co-located technical sessions with the
US committee J16. Over the past year, WG21 has timed its technical
sessions to catenate with WG14, allowing those technical experts that
would like to attend both technical sessions the opportunity to do so.
(The convener of WG21 wishes to thank the convener of WG14 for valiant
efforts at harmonious liaison.)

Fifteen countries participate by attending these meetings or by being
involved in the technical discussions that take place over the
reflector. The countries are: Austria, Canada, Denmark, Finland, France,
Germany, Ireland, Japan, Netherlands, Norway, Russia, Sweden,
Switzerland, UK, and USA.  WG21 has been monitoring the cross-language
standards activities, and made use of the ISO/IEC JTC1/WG20 guidelines on
extended characters.

3. FOCUS NEXT WORK PERIOD

3.1. DELIVERABLES

The DTR ballot for JTC 1.22.18015 Information Technology Programming
Languages Technical Report on C++ Performance (Technical Report Type 3)
is in progress.

Technical work on JTC 1.22.19768 Information Technology - Programming
Languages Technical Report of Type 2 on C++ Library Extensions (based
on ISO/IEC 14882) is expected to be completed at the October 2004 or
April 2005 meeting.

Technical work on JTC 1.22.24737 Information Technology - Programming
Languages Technical Report of Type 2 on C++ Library Extensions (based on
ISO/IEC 14882) is expected to begin in 2005. This is the second "library
extensions TR."

Technical work on JTC 1.22.24733 Information Technology - Programming
Languages Technical Report of Type 2 on Extensions for the programming
language C++ to support decimal floating point arithmetic (based on ISO/IEC
14882) is getting underway with broad liaison coordination with WG14's
similar work item.

3.2. STRATEGIES

WG believes that routine handling will suffice to complete the progress
desired.

3.3. RISKS

No problems are anticipated.

3.4. OPPORTUNITIES

Nothing new to report.

3.5. WORK PROGRAM PRIORITIES

4.3 ELECTRONIC DOCUMENT DISTRIBUTION

WG21 has conducted much of its detailed technical discussion using the
email reflector provided by the UK Association for C and C++ Users (ACCU)
and Andrew Koenig.  WG21 also has an FTP and Web site provided by courtesy
of the Danish UNIX Users Group and Keld Simonsen.  WG21 is now providing
all the appropriate committee documents on the Committee Web site, reducing
the need for paper mailings.
