CppCon 2015 constexpr: Applications--Scott Schurr

Have you registered for CppCon 2016 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 2015 for you to enjoy. Here is today’s feature:

constexpr: Applications

by Scott Schurr

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

I'm excited about constexpr. It's probably my favorite C++11 feature and it's gotten even better with C++14. But when I talk to other developers about constexpr they seem puzzled. What sorts of useful computations can the compiler possibly do before runtime?

I'd like to take this session to explore some of the capabilities that constexpr brings to the table. We'll look at compile-time parsing, floating-point computations, and containers. We'll also talk about motivations for computing these at compile time.

This session builds on the "constexpr: Introduction" talk.
