Returning multiple values from functions in C++--Eli Bendersky

By Adrien Hamelin | Mar 6, 2016 03:27 PM | Tags: None

A valid question to ask when writing functions:

Returning multiple values from functions in C++

by Eli Bendersky

From the article:

Since C++ has no built-in syntax for returning multiple values from functions and methods, programmers have been using a number of techniques to simulate this when needed, and the number has grown since the introduction of C++11. In this post I want to provide an overview of some of the options we have today for returning multiple values from functions, and possible future directions in the language...

Here is Daniel's trip report from the recent C++ meeting at Jacksonville

Trip Report C++ Meeting at Jacksonville

by J. Daniel Garcia

From the article:

First of all the bad news. Unfortunately I have to say that the outcome of the standards meeting has been disappointing. Let me explain myself. We had a really very intense week here in Jacsonville. We made progress in many things, but  we will not have the killer features I really wanted for C++17.

In detail he sums the features that were not voted into C++17 and those that were accepted.

 

CppCast Episode 47: Software Defined Visualization with Jeff Amstutz

Episode 47 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Jeff Amstutz to discuss Software Defined Visualization and Intel's SPMD Compiler.

CppCast Episode 47: Software Defined Visualization with Jeff Amstutz

by Rob Irving and Jason Turner

About the interviewee:

Jeff is a Visualization Software Engineer at Intel, where he works on the open source OSPRay project. He enjoys all things ray tracing, high performance computing, clearly implemented code, and the perfect combination of Git/CMake/modern C++. Prior to joining Intel, Jeff was an HPC software engineer at SURVICE Engineering where he worked on interactive ballistic simulation applications for the U.S. Army Research Laboratory, implemented using C++, CUDA, and Qt. When he is able, Jeff enjoys academic research in ray tracing and high performance computing, with a specific interest in multi-hit ray tracing algorithms and applications for both graphics 3D rendering and ray-based simulations.

In his spare time, Jeff enjoys powerlifting, golf, being an electric guitar nerd, and studying a wide spectrum of music ranging from progressive metal to ambient electronic music.

The monthly overview on upcoming C++ User Group meetings at Meeting C++:

C++ User Group meetings in March 2016

by Jens Weller

From the article:

A new month, and more C++ User Groups are meeting! There are more details about running your own user group at the C++ User Group page of Meeting C++. My list of User Groups contains now 65 groups, which of the most have been active in the last year, some do not meet every month but most do. This month it is again 25 User Groups which have announced their meetings sofar!

During February I found 3 new C++ User Groups: Sofia, Hannover, Nantes.

Core C++ - lvalues and rvalues--Anthony Williams

One of C++ fundamentals explained:

Core C++ - lvalues and rvalues

by Anthony Williams

From the article:

One of the most misunderstood aspect of C++ is the use of the terms lvalue and rvalue, and what they mean for how code is interpreted. Though lvalue and rvalue are inherited from C, with C++11, this taxonomy was extended and clarified, and 3 more terms were added: glvalue, xvalue and prvalue. In this article I'm going to examine these terms, and explain what they mean in practice.
