Two new Keywords in C++20: consteval and constinit
by Rainer Grimm
From the article:
With C++20 we get two new keywords: consteval and constinit. consteval produces a function that is executed at compile-time and constinit guarantees that a variable is initialized at compile-time...

Quick A: Do you need it?
Recently on SO:
Is it possible to make template specialization for zero template arguments?
If T is used only for the constructor, you don't need to template the whole class;

C++11 scoped enums deep dive and comparison with C++98 unscoped enums.
Scoped (class) enums: fundamentals and examples
by Hitesh Kumar
From the article:
Scoped enums (enum class/struct) are strongly typed enumerations introduced in C++11. They address several shortcomings of the old C-style (C++98) enums, mainly associated with type-safety and name collisions.

Polymorphic Allocators, std::vector Growth and Hacking
by Bartlomiej Filipek
From the article:
The concept of a polymorphic allocator from C++17 is an enhancement to standard allocators from the Standard Library.
It’s much easier to use than a regular allocator and allows containers to have the same type while having a different allocator, or even a possibility to change allocators at runtime.
Let’s see how we can use it and hack to see the growth of std::vector containers...

Stupid std::tuple tricks: Creating more interesting index sequences
by Raymond Chen
From the article:
Last time, we wrote offset_sequence_t, which takes an existing sequence and adds a fixed value to each element. This is the sort of index manipulation you may want to generalize. So let’s generalize it...

Stupid std::tuple tricks: Creating interesting index sequences
by Raymond Chen
From the article:
We saw last time that manipulating tuples boils down to the index_sequence. The problem is that the C++ standard library doesn’t provide very much in the way of helpers to manipulate these index sequences...

Stupid std::tuple tricks: Selecting via an index sequence, part 2
by Raymond Chen
From the article:
Last time, we developed the select_tuple function which takes a tuple and an index sequence and produces a new tuple that selects the elements based on the index sequence...

C++ Template: A Quick UpToDate Look(C++11/14/17/20)
by Vishal Chovatiya
From the article:
I know, it’s been a while since the last time I published something newbies-friendly on my blog. The main reason is that most of my readers are either experienced devs or from C background having modest C++ encounter. But while programming in C++ you need a completely different mindset as both C & C++ belongs to different programming paradigm. And I always strive to show them a better way of doing things in C++. Anyway, I found the topic which is lengthy, reasonably complex(at least it was for me), newbies-friendly as well as energizing for experienced folks(if Modern C++ jargons, rules & features added) i.e. C++ Template.
I will start with a simple class/function template and as we move along, will increase the complexity. And also cover the advance topics like the variadic template, nested template, CRTP, template vs fold-expression, etc. But, yes! we would not take deeper dive otherwise this would become a book rather than an article.
