Concept Checking in C++11 -- Eric Niebler

By Blog Staff | Nov 25, 2013 01:14 PM | Tags: intermediate advanced

While we're waiting for Concepts Lite, Eric shows how we can already do quite a bit in C++11 while planning for a transition to language support when it's available.

Concept Checking in C++11

by Eric Niebler

From the article:

This post describes some utilities I’ve recently developed for doing concept checking in C++11. These utilities are part of an ongoing project to reimplement ranges, also for C++11, but I think the concept checking utilities are useful and interesting in their own right...

Stroustrup & Sutter on C++: Mar 31 - Apr 1, San Jose, CA, USA

By Blog Staff | Nov 20, 2013 02:21 PM | Tags: intermediate basics advanced

eelive.PNGFor the first time in several years, Bjarne Stroustrup and Herb Sutter will hold a two-day seminar on C++

Super C++ Tutorial: Stroustrup & Sutter on C++

EE Live!
March 31 - April 3, 2014
San Jose, CA, USA

Are you a serious C++ developer? The two-day Super C++ Tutorial, taught by Herb Sutter and Bjarne Stroustrup, the creator of C++, is designed for active C++ developers, embedded systems developers, and anybody who works with the language on a regular basis and wants to write faster, more efficient code for applications ranging from data centers to mobile platforms where all-day battery life is key.

We invite you to spend two insightful and informative days as the instructors present the most important things C++ developers need to know in 2014. The two days are designed to cover a balanced curriculum of information: useful for C++ developers at any level, with helpful information whether you’ve only used C++ for a year or two or are a top C++ guru; balanced between language and standard library topics; covering today’s modern techniques and best practices together with forward-looking information about new features coming and expected to be broadly available in the next year; panels where both speakers share their insights and perspectives with each other and answer your questions; and much more, with the deep context and expertise that these instructors uniquely bring.

Core C++ #10 -- Stephan T. Lavavej

By Blog Staff | Nov 18, 2013 04:41 PM | Tags: intermediate basics advanced

core-10.PNGAccompanying today's release of the VC++ CTP, there is a new talk by Stephan T. Lavavej available covering several major C++11 and draft C++14 features that are of likely interest to C++ developers using any compiler.

Core C++, 10 of n (Nov 2013 CTP)

by Stephan T. Lavavej

From the summary:

In part 10, STL explores the new features in the Visual C++ Compiler November 2013 CTP (Community Technology Preview), in addition to the features that were added between VC 2013 Preview and RTM.

Features included in the November CTP ( generic lambdas!!! Smiley ):

C++11, C++14, and C++/CX features:

  • Implicit move special member function generation (thus also completing =default)
  • Reference qualifiers on member functions (a.k.a. "& and && for *this")
  • Thread-safe function local static initialization (a.k.a. "magic statics")
  • Inheriting constructors
  • alignof/alignas
  • __func__
  • Extended sizeof
  • constexpr (except for member functions)
  • noexcept (unconditional)
  • C++14 decltype(auto)
  • C++14 auto function return type deduction
  • C++14 generic lambdas (with explicit lambda capture list)
  • (Proposed for C++17) Resumable functions and await

C++11 and Boost

By Meeting C++ | Oct 17, 2013 10:11 AM | Tags: intermediate experimental c++11 boost advanced

What issues arise when combining C++11 and (older) Boost code that has pre-standard versions of C++11 features?

C++11 and Boost

by Jens Weller

From the article:

Some parts of the Standard Library in C++11 are predated in boost. When playing around with C++11, you get used to using some parts in the Standard Library that are used in C++03 with their boost counterpart. Also, there is some libraries now occuring, which are C++11 based, so interfacing with either boost or C++11 code is soon an issue.

Universal References and the Copy Constructor -- Eric Niebler

By Blog Staff | Aug 8, 2013 07:41 AM | Tags: advanced

The "universal references" term is getting traction:

Universal References and the Copy Constructor

by Eric Niebler

From the article:

At the most recent NWCPP meeting in Redmond, WA, the always-entertaining Scott Meyers shared his latest insights about so-called “universal references” and their pitfalls. In particular, he was warning about the hazards of overloading on universal references. His advice was good, I thought, but missed some important corner cases about the interactions between universal references and the special member functions. In this article, I show what the “special” problems are with the special member functions and universal references, and some ways to avoid the problems. ...

... 

Scott’s advice is simple and sound: avoid overloading on universal references. By which he means, don’t do this: 
template<typename T>
void foo( T const & t )
  {/*...*/}

template<typename T>
void foo( T && t )
  {/*...*/}

In the code above, the author presumably wanted all lvalues to go to the first and all rvalues to go to the second. But that’s not what happens. What happens is this: ...
