C++20: Structure Modules

By Rainer Grimm

When your module becomes bigger you want to divide its functionality into manageable components. C++20 modules offer two approaches: submodules and partitions. Let me discuss both approaches in this post.

A Note of Caution about Using PVS-Studio on godbolt.org (Compiler Explorer)

by Andrey Karpov

This may be promising from the perspective of satisfying one's curiosity, writing articles, and so on. But there's a downside to it too: rather than using synthetic examples to explore or try out the tool, people may start relying on them to evaluate and compare it against other analyzers. And this is a very bad approach because the results will be unreliable and dependent on how the test examples are written.

C++ Lambdas, Threads, std::async and Parallel Algorithms

by Bartlomiej Filipek

In articles about lambda expression (like this one from last week on my page), it’s easy to show examples where the lambda runs on the same thread as the caller. But how about asynchronous cases? What if your lambda is called on a separate thread? What problems you might encounter there.

Read on and let’s explore this topic...

by Jon Kalb

2020 has a been a challenging year for all of us. As C++ programmers with in-demand skills and, for most of us, the ability to work from home, we are better off than many, but it hasn’t been easy for any of us...

How to ask for C++ coding help

by Kate Gregory

Lately a lot of people have been asking me for help as they write C++ code. I’m usually happy and able to help. There are times, though, when I either cannot help, or choose not to help. I thought it might be helpful to explain some of these a little. It’s quite likely that other members of the community have a similar set of guidelines in their heads for when they do and don’t help people with code...

C++20: Module Interface Unit and Module Implementation Unit

by Rainer Grimm

Thanks to the module interface unit and the module implementation unit, you can separate the interface from the implementation when defining a module. Let me show, how...

5 Advantages of C++ Lambda Expressions and How They Make Your Code Better

by Bartlomiej Filipek

The mixture of brackets in the preceding line become one of the most noticeable indications of Modern C++.
Yep.
Lambda Expressions!
It might sound like I’m trying to create a new blog post about something that everyone knows. Is that true? Do you know all the details of this modern C++ technique?

In this article, you’ll learn five advantages of Lambdas. Let’s start...

C++20: A Simple math Module

by Rainer Grimm

Modules are one of the four prominent features of C++20. They overcome the restrictions of header files and promise a lot: faster build-times, fewer violations of the One-Definition-Rule, less usage of the preprocessor. Today, I want to create a simple math module...

C++ on Sea moves online - and into July

We decided to move the workshops a little further away, since we no longer have the constraints imposed by venue, accommodation and travel - but we do want to reduce the number of consecutive days people will need to spend watching online.

The workshops will also run on different days from each other - so, potentially, you could attend more than one!
