East End Functions

by Phil Nash

There has been a recent stirring of attention, in the C++ community, for the practice of always placing the const modifier to the right of the thing it modifies. The practice has even been gifted a catchy name: East Const (which, I think, is what has stirred up the interest)...

Class Templates

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

The Subtle Dangers of Temporaries in for Loops

by Jonathan Boccara

Even though very convenient to write concise code, temporaries are an endless source of bugs in C++.

Are we allowed to use a temporary in a range based for loop?

Function Templates - More Details about Explicit Template Arguments and Concepts

by Rainer Grimm

In the last post "Function Templates", I wrote about the overloading of function templates and automatically deducing the return type of a function template. Today, I dive deeper and specify explicitly the template arguments of a function template and bring concepts into the play...

Predefined C++20 Concepts: Callables

by Bartlomiej Filipek

Before you start implementing your custom concepts, it’s good to review some goodies in the Standard Library. There’s a high chance that there’s already a predefined concept for you.

Today let’s have a look at concepts related to callable objects...

A Default Value to Dereference Null Pointers

by Jonathan Boccara

With C++17, modern C++ has acquired a nullable object: std::optional. optional has a pretty rich interface, in particular when it comes to handling null optionals.

On the other hand, the oldest nullable type in C++, pointers, doesn’t have any helper to make the handling of its nullity more expressive.

Let’s see what we can do about it, to make our code using pointers, smart or raw, easier to read...

C++20 Coroutine: Under The Hood

by Vishal Chovatiya

A coroutine is one of the major feature introduced with the C++20 standard apart from Module, Ranges & Concept. And you see how happy I am to unfold it. I already set the baseline on this topic with my previous article that Coroutine in C Language, where we saw, how suspension-resumption of execution works! With this article “C++20 Coroutine: Under The Hood”, we will see how compiler creates magic & standard library helps it with basic infrastructure making C++20 coroutine more sophisticated(yet complex) & scalable/customizable...

Report from the virtual ISO C++ meetings in 2020 (core language)

by Jason Merrill

C++ standardization was dramatically different in 2020 from earlier years. The business of the International Organization for Standardization (ISO) committee all took place virtually, much like everything else during this pandemic. This article summarizes the C++ standardization proposals before the Core and Evolution Working Groups last year...
