C++ Templates: How to Iterate through std::tuple: the Basics

by Bartlomiej Filipek

From the article:

If you have a standard container, it’s easy to use a range-based for loop and iterate over its elements at runtime. How about std::tuple? In this case, we cannot use a regular loop as it doesn’t “understand” tuple’s compile-time list of arguments. That’s why in this article, I’ll show you a few techniques you can use to run through all tuple’s entries...

The Usual Arithmetic Confusions--Shafik Yaghmour

Do you know the conversions?

The Usual Arithmetic Confusions

by Shafik Yaghmour

From the article:

There are a lot of aspects of C++ that are not well understood and lead to all sorts of confusion. The usual arithmetic conversions and the integral promotions are two such aspects. Certain binary operators (arithmetic, relational and spaceship) require their operands to have a common type. The usual arithmetic conversions are the set of steps that gets operands to a common type. While the integral promotions brings integral types smaller than int and unsigned int to either int or unsigned int depending on which one can represent all the values of the source type. This is one of the areas in C++ that comes directly from C, so pretty much all of these examples applies to C as well as C++...

Giving you a short overview on what Meeting C++ plans for 2022!

The next two events happening at the Meeting C++ online user group:

Also the next Meeting C++ job fair is on the 15th and 16th March, I plan to host one per quarter of each fair.

Meeting C++ 2022

Its going to be a hybrid event in Berlin and online from November 16-19th. I'll start the conference season for Meeting C++ again in April, so expect further annoucements and the opening for the call for talks then. Same goes for tickets, sponsorship and more.

Fixing the crash that seems to be on a std::move operation--Raymond Chen

Which way do you prefer?

Fixing the crash that seems to be on a std::move operation

by Raymond Chen

From the article:

Last time, we looked at a crash that was root-caused to an order of evaluation bug if compiled as C++14. One solution to the problem is to switch to C++17 mode, but presumably the customer isn’t willing to make that drastic a change to their product yet. Maybe there’s something we can do that is less disruptive...

How we used C++20 to eliminate an entire class of runtime bugs--Cameron DaCamara

Always more powerful.

How we used C++20 to eliminate an entire class of runtime bugs

by Cameron DaCamara

From the article:

C++20 is here and has been supported in MSVC since 16.11, but today’s post is not about how you can use it, but rather how we used it to effectively eliminate an entire class of runtime bugs by hoisting a check into compile-time. Let’s get right into it!
