C++ is standardized by an [[International Organization for Standardization|ISO]] working group known as [[ISO/IEC JTC 1/SC 22|JTC1/SC22/WG21]]. So far, it has published seven revisions of the C++ standard and is currently working on the next revision, [[C++26]].

[[File:C++ Standards Committee meeting - July 1996 Stockholm - Wednesday general session.jpg|thumb|right|Scene during the C++ standards committee meeting in Stockholm in 1996]]
In 1998, the ISO working group standardized C++ for the first time as ''ISO/IEC 14882:1998'', which is informally known as ''C++98''. In 2003, it published a new version of the C++ standard called ''ISO/IEC 14882:2003'', which fixed problems identified in C++98.

The next major revision of the standard was informally referred to as "C++0x", but it was not released until 2011.<ref name="0xapprove">{{cite web|url=https://herbsutter.com/2011/08/12/we-have-an-international-standard-c0x-is-unanimously-approved/|title=We have an international standard: C++0x is unanimously approved|website=Sutter's Mill|date=12 August 2011|access-date=23 November 2018|archive-date=28 June 2018|archive-url=https://web.archive.org/web/20180628182816/https://herbsutter.com/2011/08/12/we-have-an-international-standard-c0x-is-unanimously-approved/|url-status=live}}</ref>  [[C++11]] (14882:2011) included many additions to both the core language and the standard library.<ref name="isocpp2011"/>

In 2014, [[C++14]] (also known as C++1y) was released as a small extension to C++11, featuring mainly bug fixes and small improvements.<ref name="The Future of C">{{Cite web|url=https://channel9.msdn.com/Events/Build/2012/2-005|title=The Future of C++|via=channel9.msdn.com|access-date=23 November 2018|archive-date=23 October 2018|archive-url=https://web.archive.org/web/20181023213741/https://channel9.msdn.com/Events/Build/2012/2-005|url-status=live}}</ref>  The Draft International Standard ballot procedures completed in mid-August 2014.<ref>{{Cite web|url=https://isocpp.org/blog/2014/08/we-have-cpp14|title=We have C++14! : Standard C++|website=isocpp.org|access-date=19 August 2014|archive-date=19 August 2014|archive-url=https://web.archive.org/web/20140819083101/https://isocpp.org/blog/2014/08/we-have-cpp14|url-status=live}}</ref>

After C++14, a major revision [[C++17]], informally known as C++1z, was completed by the ISO C++ committee in mid July 2017 and was approved and published in December 2017.<ref name="Toronto meeting report">{{Cite web|url=https://herbsutter.com/2017/07/15/trip-report-summer-iso-c-standards-meeting-toronto/|title=Trip report: Summer ISO C++ standards meeting (Toronto)|first=Herb|last=Sutter|date=15 July 2017|access-date=4 August 2017|archive-date=6 August 2017|archive-url=https://web.archive.org/web/20170806182136/https://herbsutter.com/2017/07/15/trip-report-summer-iso-c-standards-meeting-toronto/|url-status=live}}</ref>
