Policy
Thanks to templates, there are new ways of software design. Policies and traits are two commonly used idioms in C++.

Avoiding Temporaries with Expression Templates
Expression templates are typically used in linear algebra and are “structures representing a computation at compile-time, which are evaluated only as needed to produce efficient code for the entire computation” (https://en.wikipedia.org/wiki/Expression_templates). In other words, expression templates are only evaluated when needed.

Mixins
In my previous post “More about Dynamic and Static Polymorphism”, I used the Curiously Recurring Template Pattern (CRTP) to implement static polymorphism. Another typical use case for CRTP is mixins.

More about Dynamic and Static Polymorphism
In my last post, “Dynamic and Static Polymorphism“, I introduced dynamic polymorphism. Today, I continue with static polymorphism and present a very interesting idiom in C++: curiously recurring template pattern (CRTP).

Dynamic and Static Polymorphism
Polymorphism is the property that different types support the same interface. In C++, we distinguish between dynamic polymorphism and static polymorphism.
constexpr if
In today’s post, I want to introduce an exciting C++17 feature: constexpr if. constexpr if enables it to compile source code conditionally and can be used for nice tricks at compile time.
constexpr and consteval Functions in C++20
With C++20, constexpr became way more powerful. Additionally, we have consteval functions in C++20 that are quite similar to constexpr functions.
