C++20: The Unspoken Features -- Michele Caini

By HumanReadableIO | Jun 17, 2020 01:23 PM | Tags: None

Modules, coroutines, concepts, and ranges, oh my. Here comes C++ 20. The big four new features are getting all the buzz, but what about the smaller features? 

C++20: The Unspoken Features

by Michele Caini

From the article:

What's new in C++ besides the big four? A lot of things. We certainly won't be able to see them all in one post. Among the most interesting (at least from my point of view) are the following:

• Designated initializers
• Spaceship operator
• Extended range-based for statement
• Pack expansions in lambda init-capture
• Template parameter lists on lambdas
• String literals as template parameters
• consteval and constinit keywords
• Constexpr containers
• Constexpr virtual functions

enable_shared_from_this - overview, examples, and internals

by Hitesh Kumar

From the article:

Public inheritance from enable_shared_from_this<T> enables a class T to  create additional shared_ptr instances to itself. Typically, enable_shared_from_this holds a weak_ptr to create shared_ptr on demand.

C++20: The Three-Way Comparison Operator

by Rainer Grimm

From the article:

The three-way comparison operator <=> is often just called spaceship operator. The spaceship operator determines for two values A  and B whether A < B, A = B, or A > B. You can define the spaceship operator or the compiler can auto-generate it for you...

This paper focuses on the major changes to the ISO C++ standard for the 2011, 2014, 2017, and 2020 revisions.
The standard library is about 3/4 of the C++20 standard, but this paper’s primary focus is on language features
and the programming techniques they support.

C++20: Further Open Questions to Modules

by Rainer Grimm

From the article:

So far, I have written in my last four posts the basics you should know about modules in C++20. Only a few questions to modules are still open. In this post, I address these open questions, such as templates in modules, the linkage of modules, and header units.
