Another new feature.
C++17: Attributes
by Marc Gregoire
From the article:
C++17 introduces three new code attributes:
- [[fallthrough]]
- [[maybe_unused]]
- [[nodiscard]]
The first one was discussed in detail in my C++17: Fallthrough in switch statements blog post. The others are briefly explains below...

A collection of personal notes and thoughts on rvalue references, their role in move semantics and how they can significantly increase the performance of your applications.
C++ rvalue references and move semantics for beginners
by Triangles @ internalpointers.com
From the article:
In my previous article Understanding the meaning of lvalues and rvalues in C++ I had the chance to explain to myself the logic behind rvalues. The core idea is that in C++ you will find such temporary, short-lived values that you cannot alter in any way.
Surprisingly, modern C++ (C++0x and greater) has introduced rvalue references: a new type that can bind to temporary objects, giving you the ability to modify them. Why?

Quick A: the type of the function must be explicit.
Recently on SO:
std::bind overload resolution
You need a cast to disambiguate the overloaded function:
(int(A::*)(int,int))&A::operator()

Quick A: Only your own type can be accessed.
Recently on SO:
Accessing protected members in a derived class
You can only access protected members in instances of your type (or derived from your type).
You cannot access protected members of an instance of a parent or cousin type.In your case, the Derived class can only access the b member of a Derived instance, not of a different Base instance.
Changing the constructor to take a Derived instance will also solve the problem.

Triple trip report from ACCU, C++ Russia and C++Now 2018 – Part 1
by Jonathan Boccara
From the article:
Going to conferences is a great experience, to learn about your domain and meet people that work in it. Going to conferences can give you tools to write better code.
I’ve had the chance to go to (and speak at) three conferences over a month:
- ACCU in Bristol, UK at the beginning of April,
- C++ Russia in Saint-Petersburg, Russia in mid April,
- C++Now in Aspen, US at the beginning of May.
I haven’t seen many people attending all three of them, so I figured I could make a combined trip report, to give you an idea of what they’re like. And more importantly what you would get by attending either one.
And a huge thanks to the company I work for, Murex, for sending me all over the world of C++!
