This document is written by and maintained by Bjarne Stroustrup. Constructive comments, correction, references, and suggestions are of course most welcome. Currently, I'm working to improve completeness and clean up the references.
C++0x is the next ISO C++ standard. Currently a draft is available for comments. The previous (and current) standard is often referred to as C++98 or C++03; the differences between C++98 and C++03 are so few and so technical that they ought not concern users.
The final committee draft standard is currently (March 2010) being voted on by the national standards bodies. After that there will be more work before all comments have been addressed and the ISO bureaucracy satisfied. At the current stage of the proceedings, no features (even very minor ones) are expected to be added or removed. The name "C++0x" is a relict of the days where I and others, hoped for a C++08 or C++09. However, to minimize confusion, I'll keep referring to the upcoming C++ standard with the feature set defined here as C++0x. Think of 'x' as hexadecimal (most likely 'B', i.e. C++11).
If you have comments on C++0x, please find some member of your national standards body -- or a member of any standards body -- to send your comments to. That's now the only way and will ensure that the committee doesn't have to deal with many very similar comment. Remember, the committee consists of volunteers with limited time and resources.
All official documents relating to C++0x can be found at the ISO C++ committee's website. The official name of the committee is SC22 WG21.
Caveat: This FAQ will be under construction for quite a while. Comments, questions, references, corrections, and suggestions welcome.
Purpose
The purpose of this C++0x FAQ is
To give an overview of the new facilities (language features and standard libraries) offered by C++0x in addition to what is provided by the previous version of the ISO C++ standard.
To give an idea of the aims of the ISO C++ standards effort.
To present a user's view of the new facilities
To provide references to allow for a more in depth study of features.
To name many of the individuals who contributed (mostly as authors of the reports they wrote for the committee). The standard is not written by a faceless organization.
Please note that the purpose of this FAQ is not to provide comprehensive discussion of individual features or a detailed explanation of how to use them. The aim is to give simple examples to demonstrate what C++0x has to offer (plus references). My ideal is "max one page per feature" independently of how complex a feature is. Details can often be found in the references.
