C++0x (pronounced see plus plus oh ex) is the unofficial name of the planned new standard for the C++ programming language. It is intended to replace the existing C++ standard, ISO/IEC 14882, which was published in 1998 and updated in 2003. These predecessors are informally known as C++98 and C++03. The new standard will include several additions to the core language and will extend the C++ standard library, incorporating most of the C++ Technical Report 1 (TR1) libraries — most likely with the exception of the library of mathematical special functions. Since the standard is not yet finalized, this article may not reflect the most recent state of C++0x. The draft international standard, N3092, was published in March 2010.
