Dev C%2b%2b 11 Support
Clang fully implements all published ISO C++ standards(C++98 / C++03,C++11,C++14, andC++17), and some of the upcoming C++20 standard.
If you must use Dev C, try the following: 1. Click to Tools Compiler Options. Click to Settings Code Generation. Change the value of Language Standard (-std) to ISO C11. Because the upstream GCC community development does not guarantee C11 ABI compatibility across major versions of GCC, the same applies to use of C11 with Red Hat Developer Toolset. Consequently, using the -std=c11 option is supported in Red Hat Developer Toolset 3.x only when all C objects compiled with that flag have been built using. Created by LolRiTTeR#1258. Welcome to 2b2t.dev! Check out the stuff I made so far: Priority Queue LolRiTTeRBot API 2b2t Tablist. Visual C 2012 (also known as Visual C 11.0) was released on August 15, 2012. It features improved C11 support, and support for Windows Runtime development. Visual C 2013 (also known as Visual C 12.0) was released on October 17, 2013. It features further C11 and C99 support.
The Clang community is continually striving to improve C++ standardscompliance between releases by submitting and tracking C++ Defect Reports and implementing resolutionsas they become available.
Experimental work is also under way to implement C++ TechnicalSpecifications that will help drive the future of the C++ programminglanguage.
The LLVM bug tracker contains ClangC++ components that track known bugs with Clang's language conformance ineach language mode.
C++98 implementation status
Clang implements all of the ISO C++ 1998 standard (including the defects addressed in the ISO C++ 2003 standard) except for export (which was removed in C++11).
C++11 implementation status
Clang 3.3 and later implement all of the ISO C++ 2011 standard.
By default, Clang builds C++ code according to the C++98 standard, with manyC++11 features accepted as extensions. You can use Clang in C++11 mode with the-std=c++11
option. Clang's C++11 mode can be usedwith libc++ or with gcc's libstdc++.

would be an ABI-incompatiblechange.
C++14 implementation status

added these functions in version 5.0, and libc++
added them inversion 3.7.

(8): This is a backwards-incompatible change that is applied toall language versions that allow type deduction from auto(per the request of the C++ committee).In Clang 3.7, a warning is emitted for all cases that would change meaning.
(9): Under the MS ABI, function parameters are destroyed fromleft to right in the callee. As a result, function parameters in calls tooperator<<, operator>>, operator->*,operator&&, operator , and operator,functions using expression syntax are no longer guaranteed to be destroyed inreverse construction order in that ABI.This is not fully supported during constant expression evaluation until Clang 12.
(10): Despite being the resolution to a Defect Report, thisfeature is disabled by default in all language versions, and can be enabledexplicitly with the flag -frelaxed-template-template-args in Clang 4onwards.The change to the standard lacks a corresponding change for template partialordering, resulting in ambiguity errors for reasonable and previously-validcode. This issue is expected to be rectified soon.
C++20 implementation status
Clang has support for some of the features of theISO C++ 2020 Draft International Standard.

Defect reports
Clang generally aims to implement resolutions to Defect Reports (bug fixesagainst prior standards) retroactively, in all prior standard versions wherethe fix is meaningful. Significant Defect Report changes to language featuresafter the publication of the relevant standard are marked (DR) in the abovetable.
Clang also has a test suite for conformance to resolutions for issues on theC++ core issues list,most of which are considered Defect Reports.Implementation status for C++ core issues based onthat test suite is tracked on a separate page.
Technical specifications and standing documents
ISO C++ also publishes a number of documents describing additional languageand library features that are not part of standard C++.
