To the untrained eye, pure functional programming may appear to be out of place in our traditionally imperative C++ world. However, the functional paradigm has become increasing prominent in production C++ codes, especially when implementing asynchronous execution.
This talk is intended as a primer for attendees who are either unfamiliar with functional programming or have doubts its practical uses in modern C++. The following topics will be covered:
* Functions with Clear Inputs/Outputs (side effects, referential transparency/value semantics)
* Functions as First-Class Entities (function objects, C++11 lambda functions, Callable/std::function)
* The Algebra of Functions (higher-order functions/<algorithm>, currying/std::bind, composition)
* Down the Rabbit Hole: Monads and Parallelism (calling functions/std::async, std::future, .then()/when_all(), futurization)
Examples from different sectors of industry/academia will be presented throughout.
No prior functional programming knowledge will be needed. While this talk will cover some theory, coverage of non-C++ programming languages will be minimal. The focus of this talk will be the application of theories from FP to C++, not FP itself.
