Have you registered for CppCon 2017 in September? Don’t delay – Registration is open now.
While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2016 for you to enjoy. Here is today’s feature:
Implementing `static` control flow in C++14
by Vittorio Romeo
Summary of the talk:
There has always been great interest in imperative compile-time control flow: as an example, consider all the existing `static_if` proposals and the recently accepted `constexpr_if` construct for C++17.
What if you were told that it is actually possible to implement imperative control flow in C++14?
In this tutorial, the implementation and design of a compile-time `static_if` branching construct and of a compile-time `static_for` iteration construct will be shown and analyzed. These constructs will then be compared to traditional solutions and upcoming C++17 features, examining advantages and drawbacks.
