Demystifying constexpr

by Edouard from quasardb

From the article:

C++ 11 and C++ 14 came with a lot of new features. People tend to focus on lambdas and rvalue references, but today I’d like to talk about constexpr.

In this post we'll only talk about constant expressions as in C++ 14. There is absolutely no point to restrict yourself to C++ 11 in 2016. C++ 14 is really C++ 11 Service Pack 1, so if you missed the update, go straight to C++ 14!
