View source for C++03

'''C++03''' is a version of the [[Organization:International Organization for Standardization|ISO]]/[[Organization:International Electrotechnical Commission|IEC]] 14882 standard for the [[C++]] programming language. It is defined by two [[Engineering:Standards organization|standards organization]]s, the [[Organization:International Organization for Standardization|International Organization for Standardization]] (ISO) and the [[Organization:International Electrotechnical Commission|International Electrotechnical Commission]] (IEC), in standard ISO/IEC 14882:2003.

C++03 replaced the prior [[C++#Standardization|C++98]] standard. C++03 was later replaced by [[C++11]]. C++03 was primarily a bug fix release for the implementers to ensure greater consistency and portability.<ref name="bsfaq">{{cite web|url=http://www.stroustrup.com/bs_faq.html#C++03 |title=Bjarne Stroustrup's FAQ – What is the difference between C++98 and C++03? |publisher=Bjarne Stroustrup's homepage |url-status=dead |archiveurl=https://web.archive.org/web/20160206214150/http://www.stroustrup.com/bs_faq.html#C++03 |archivedate=February 6, 2016 }}</ref> This revision addressed 92 core language defect reports,<ref>{{Cite web|url=https://open-std.org/JTC1/SC22/WG21/docs/cwg_status.html|title=C++ Standard Core Language Issue Index by Status: Issues with "TC1" Status|website=open-std.org|access-date=2022-09-20|archive-date=2022-09-11|archive-url=https://web.archive.org/web/20220911162749/https://open-std.org/JTC1/SC22/WG21/docs/cwg_status.html|url-status=live}}</ref> 125 library defect reports,<ref>{{Cite web |url=https://open-std.org/JTC1/SC22/WG21/docs/lwg-status.html#TC1 |title=C++ Standard Library Issues List: TC1 (125 issues) |access-date=2016-05-30 |archive-date=2018-07-21 |archive-url=https://web.archive.org/web/20180721143959/http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-status.html#TC1 |url-status=live }}</ref> and included only one new language feature: value initialization.<ref>{{Citation| url = https://en.cppreference.com/w/cpp/language/value_initialization| contribution = Value initialization| title = C++ reference| type = wiki| access-date = 2016-05-30| archive-date = 2018-05-27| archive-url = https://web.archive.org/web/20180527065630/http://en.cppreference.com/w/cpp/language/value_initialization| url-status = live}}</ref>

Among the more noteworthy defect reports addressed by C++03 was the library defect report 69,<ref>{{Cite web |url=https://open-std.org/JTC1/SC22/WG21/docs/lwg-defects.html#69 |title=C++ Standard Library Defect Report List: 69.

While most implementations satisfied this expectation, it was not required by C++98.
