constexpr is a feature added in C++ 11. constexpr specifies that the value of an object or a function can be evaluated at compile time and the expression can be used in other constant expressions.

constexpr functions are functions that can be executed at compile time. Sounds not so thrilling. But it is. Trust me. You can perform with constexpr functions a lot of calculations at compile time.

constexpr variables are const. This will get important when we talk about other effects of const in upcoming lessons. A better way to create symbolic constants is through use of constexpr variables
C++ - constexpr functions | c++ Tutorial
https://riptutorial.com/cplusplus/example/16201/constexpr-functions
C++ constexpr functions. Example. A function that is declared constexpr is implicitly inline and calls to such a function potentially yield constant expressions.
constexpr` is a Platform

Let me share a useful insight with you: constexpr is a platform. Just like you write code that targets Windows or a microcontroller, you write code that targets compile-time execution.
Constexpr Additions in C++17 - Simplify C++!
https://arne-mertz.de/2017/03/constexpr-additions-c17/
constexpr closure object constexpr auto add5 = adder(5) However with the old if, the other branch still had to compile. With if constexpr that is no longer the case, the compiler will no longer attempt that.
constexpr if - 7 Features of C++17 that will simplify your code
https://www.codingame.com/playgrounds/2205/7-features-of-c17-that-will-simplify-your-code/constexpr-if
Hmm... constexpr if can be used to replace several tricks that were already done So, in most of the cases, we can now just write a constexpr if statement and that will yield much cleaner code.

The Missing for constexpr

With C++17 we finally get if constexpr. However, I have started running into a lot of cases where I want a for constexpr that is guaranteed to be evaluated at compile time.
