Explore functional programming concepts and their implementation in C++ through this comprehensive conference talk from code::dive 2016. Delve into the fundamentals of functional programming, comparing Haskell and C++ implementations of key features such as pure functions, higher-order functions, closures, and lazy evaluation. Learn about algebraic data types, pattern matching, and category theory concepts like functors and applicatives. Gain insights into how C++, a multi-paradigm language, supports functional programming constructs and techniques. Discover practical examples and code demonstrations that illustrate the application of functional programming principles in C++, enhancing your understanding of this powerful programming paradigm.
