C++ Insights - Variadic Templates
by Rainer Grimm
From the article:
Variadic templates are a C++ feature which looks quite magic the first time you see it. Thanks to C++ Insights, most of the magic disappears...

ACCU’s Overload journal of April 2019 is out. It contains the following C++ related articles.
Overload 150 is now available
From the journal:
This means war!.
Careless use of language can upset people. Frances Buontempo asks what we can do to make the developer experience better.NullableAttribute and C# 8.
C# 8 will bring many new features. Jon Skeet investigates the metadata representation of Nullable Reference Types.lvalues, rvalues, glvalues, prvalues, xvalues, help!.
C++11 introduced new value categories. Anders Schau Knatten explains his way of thinking about them.Modern SAT solvers: fast, neat and underused (part 1 of N).
SAT solvers can quickly find solutions to Boolean Logic problems. Martin Hořeňovský demonstrates how this can be used to solve arbitrary Sudoku puzzles.The Duality….
Genetic algorithms can find solutions that other algorithms might miss. Anders Modén discusses their use in conjunction with back-propagation for finding better solutions.Blockchain-Structured Programming.
Coins are a wedge-shaped piece used for some purpose. Teedy Deigh shares her angle on the technology underpinning crypto-currencies.

The BooSTL Algorithms: Boost Algorithms That Extend the STL (3/3)
by Jonathan Boccara
From the article:
The BooSTL algorithms are what we can call the Boost algorithms which are in the same spirit as those of the STL. They encapsulate operations on collections, and being able to use them allows to write (or re-write) more expressive code. To cover all their contents, we split up the articles of the BooSTL into three parts:
- the BooSTL algorithms on sorting and partitioning,
- the BooSTL algorithms on searching,
- the other BooSTL algorithms.
So here we go to cover the rest of the BooSTL algorithms which are not in sorting, partitioning nor searching.

Quick A: Use the normal template declaration.
Recently on SO:
C++ template typedef
C++11 added alias declarations, which are generalization of typedef, allowing templates:
template <size_t N> using Vector = Matrix<N, 1>;The type Vector<3> is equivalent to Matrix<3, 1>.

The BooSTL Algorithms: Boost Algorithms That Extend the STL (2/3)
by Jonathan Boccara
From the article:
One good way to extend our knowledge beyond the STL is to learn the Boost STL-like algorithms. I like to call them the BooSTL algorithms. To cover all the contents in this algorithms library, we have chunked up the story into three parts:
- the BooSTL algorithms on sorting and partitioning,
- the BooSTL algorithms on searching,
- the other BooSTL algorithms.
After seeing the BooSTL algorithms on sorting and partitioning, we are now going to focus on BooSTL algorithms on searching...

The BooSTL Algorithms: Boost Algorithms That Extend the STL (1/3)
by Jonathan Boccara
From the article:
The STL features a proud 105 algorithms, but that is by no means all the algorithms there is in C++.
There are many ways to extend the STL. One of them is to include the STL-like algorithms that are in Boost, which I like to call the BooSTL algorithms!

Trip Report: C++ Standards Meeting in Kona, February 2019
by Botond Ballo
From the article:
A few weeks ago I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Kona, Hawaii. This was the first committee meeting in 2019; you can find my reports on 2018’s meetings here (November 2018, San Diego), here (June 2018, Rapperswil), and here (March 2018, Jacksonville). These reports, particularly the San Diego one, provide useful context for this post...

Macro Evil in C++ Code
by Andrey Karpov
From the article:
The C++ language opens extensive opportunities to go without macros. So let’s try to use macros as seldom as possible!

Quick A: each release of C++ allows more things to be done at compile time.
Recently on SO:
Compile-time loop optimisation
In C++14, constexpr function requirements were relaxed.
Previously, in C++11, constexpr functions could only contain typedefs, static_asserts and usings, but only a single return statement.
In C++14, it became possible to use loops in constexpr function bodies.
Because b was declared as constexpr char, it must be evaluated at compile time. The compiler then optimised out the isStringNice function, as it is not used at run time.
