Higher Order Functions for Ordinary C++ Developers

Explore higher order functions in C++ through this comprehensive conference talk. Learn simple techniques for writing functions that accept or return other functions, elevating code abstraction and readability while reducing duplication. Discover how to maintain performance while implementing these advanced concepts. Examine practical examples using Compiler Explorer, including IP address handling, predicate composition, and state management. Investigate the benefits of higher order functions in arranging code, handling lambdas, and solving common programming challenges. Delve into function categories, boost libraries, and composition naming conventions. Gain valuable insights on improving C++ code quality and efficiency through the effective use of higher order functions.
