Template Arguments--Rainer Grimm

The series continue.

Template Arguments

by Rainer Grimm

From the article:

It is quite interesting how the compiler deduces the types for the template arguments. To make it short, you get most of the time the type you expect. The rules do not only apply to function templates (C++98) but also to auto (C++11), to class templates (C++17), and concepts (C++20)...

Class Templates--Rainer Grimm

The series continue.

Class Templates

by Rainer Grimm

From the article:

A function template represents a family of functions. Accordingly, a class template represents a family of classes. Today, I want to introduce class templates...

Templates - First Steps--Rainer Grimm

A powerful tool.

Templates - First Steps

by Rainer Grimm

From the article:

The idea of this post is quite simple. I want to visualize templates and, in particular, the process of template instantiation. Thanks to C++ Insights, this visualization is pretty easy...

The most popular C++ standard features

The next article on the results from the Meeting C++ survey

The most popular C++ standard features

by Jens Weller

From the article:

Continuing the series about the Meeting C++ survey results with a look at the standard features. Last week I compared the ISOCPP survey to the one of Meeting C++.

When I was looking into the questions I could ask in the survey tool, it came to my mind that it would be interesting to know more about the details of standards, not just asking for which standard folks use in various ways. So in this blog post, I'm going to show you the questions about standard feature usage.

Mathematical constants in C++20

Hightlighting a less known C++20 feature:

Mathematical constants in C++20

by Jens Weller

From the article:

When I researched the library and language features of C++20 for the Meeting C++ Community survey, this feature catched my eye.

And I thought its such a nice small feature, I should mention it on the blog. As all other C++20 blog posts right now seem to be about coroutines. It also is a nice follow up on an old blog of mine: C++ & π, where I showed the various ways of obtaining pi for C++ in 2013...

The monthly list of upcoming C++ User Group meetings, still online due to the pandemic!

In April Meeting C++ online hosts two different events: on April 8th Andreas Fertig will speak about C++ insights and on April 20th Meeting C++ hosts an online C++ Tool fair.

There is 1 new C++ User Group: Vorarlberg.

Taming the power of C++ with AI

A new blog article on an exciting idea for C++

Taming the power of C++ with AI

by Jens Weller

From the article:

In January Bryce Adelstein Lelbach gave a talk about NDVIDIAS CUDASTL fork at my online C++ User Group. Shortly after this talk was published on YouTube I got contacted by a start up, seeking feedback on their ideas of accelerating C++ with help of GPUs and AI...

C++ Fold Expressions 101--Jonathan Boccara

Back to the basics.

C++ Fold Expressions 101

by Jonathan Boccara

From the article:

C++17 brought fold expressions to the language. This interesting feature allows to write expressive code, that almost seems magical.

Here is a two-posts recap on how fold expressions work (this post) and how they can improve your code (the next post).
