C++ Modules conformance improvements with MSVC in Visual Studio 2019 16.5

by Cameron DaCamara

C++20 is right around the corner. Along with the new standard comes the much anticipated Modules feature! The compiler team initially announced that we were working on the Modules TS back in 2017 and since then we have been hard at work improving the feature and improving compiler conformance around this feature. We finally feel it is time to share some of the progress we have made on the conformance front for Modules...

How to Short-Circuit a Sequence of Operations with a Boolean Value

by Jonathan Boccara

Interrupting a sequence of operations when one of them fails is a common problem in computer programming. There are plenty of elaborate ways to code that, ranging from exceptions to monads to static exceptions.

One of the techniques to stop such a sequence of operations that is not so sophisticated, but that can be found in existing code, is to use a boolean. This relies on each step producing a boolean flag to indicate if it succeeded or failed, and to stop executing steps at the first failure.

However, simple as it is, this technique can lead to code that doesn’t do with it looks like...

The C++ Lifetime Profile: How It Plans to Make C++ Code Safer

by Daniel Martín

High amounts of low-level systems are written in C++. Memory access in C++ is virtually unrestricted, which means that bugs in C++ programs can corrupt it and cause crashes or security problems. For this reason, we call C++ a memory-unsafe programming language — in contrast to memory-safe languages like Java, Rust, and Swift.

In this blog post, I’ll talk about the C++ Lifetime Profile, explaining what it is, how it intends to reduce the problems typically caused by the memory-unsafe characteristics of C++, what the status of the current implementation of the Lifetime Profile is, and what the current limitations are...

The Hunt for the Fastest Zero

by Travis Downs

Let’s say I ask you to fill a char array of size n with zeros. I don’t know why, exactly, but please play along for now.

If this were C, we would probably reach for memset, but let’s pretend we are trying to write idiomatic C++ instead...

"Use the Force, Luke"... or Modern C++ Tools

by Bartlomiej Filipek

In this blog post, I’d like to show you how I could quickly improve my old project with Modern C++. Thanks to using the newest compilers and free code analysis checkers you can cover and modernise a lot of code...

Early bird tickets for Core C++ 2020 are now on sale!

Adi Shavit

From medical devices and flash storage to CPUs and advanced navigation systems, Israeli innovation pushes the boundaries of the imagination. Advanced software is at the heart of many of these systems, and when it comes to bare-metal performance, low power-consumption and massive scalability, C++ is king. Core C++ 2020 will take place at The Wohl Conventions Center, located just outside Tel-Aviv on the campus of Bar-Ilan University in Ramat Gan, Israel.
The conference is aimed at C++ developers and practitioners as well as academic researchers and teachers who wish to be updated by the newest developments of C++ and present their work with C++. International speakers and attendees are more than welcome to join us!
