Atomic Smart Pointers

C++20 will have atomic smart pointers. To be exactly, we will get a std::atomic_shared_ptr and a std::atomic_weak_ptr. But why? std::shared_ptr and std::weak_ptr are already thread-safe. Sort of. Let me dive into the details.

Parallel Algorithms of the Standard Template Library

The idea is quite simple. The Standard Template has more than 100 algorithms for searching, counting, and manipulating of ranges and their elements. With C++17, 69 of them are overloaded and a few new are added. The overloaded and new algorithms can be invoked with a so-called execution policy. By using the execution policy, you can specify whether the algorithm should run sequential, parallel, or parallel and vectorised.

Multithreading with C++17 and C++20

Forecasts about the future are difficult. In particular, when they are about C++20. Nevertheless, I will take a look into the crystal ball and will write in the next posts about, what we will get with C++17  and what we can hope for with C++20.

Expression Templates

Expression templates are "structures representing a computation at compile time, which structures are evaluated only as needed to produce efficient code for the entire computation" (https://en.wikipedia.org/wiki/Expression_templates). As needed, now we are in the centre of lazy evaluation and in the centre of this post.

C++ is Lazy: CRTP

In my previous post Recursion, List Manipulation and Lazy Evaluation I wrote about the characteristics of functional programming:  The story about lazy evaluation in C++ is short. Sorry to say but I have forgotten templates. The two advanced techniques CRTP and expression templates are based on lazy evaluation.

Monads in C++

Monads in C++? What a strange name for a post. But it's not so strange. With std::optional C++17 gets a monad. The ranges library from Eric Niebler and the extended futures are also monads. For both, we can hope for in C++20.

Concepts

We stay in the year 2020. With high probability we will get concepts. Of course, waterproof statements about the future are difficult but the statement is from Bjarne Stroustrup (Meeting C++ 2016 at Berlin).

The New Ranges Library

A small time jump and we are in the year 2020. C++ will get - as far as the future is predictable - the new ranges library. Thanks to Eric Nieblers library, the working with the Standard Template Library (STL) will become much more comfortable and powerful.
