Keynote: Functional Programming in C++ - Jonathan Müller - C++Online 2025
Functional programming is a declarative way of writing programs by composing functions. In many situations, this can lead to code that is easier to write and understand and less error-prone. However, it requires a shift to a more functional mindset. This talk gives an introduction to functional programming in C++ using the modern standard library. We will cover algorithms using std::ranges, composable error handling with std::optional and std::expected, algebraic data types, and separating IO from computation. In the end, we'll even cover the M-word.

C++Online is the annual, online only conference for the entire C++ community. The conference is designed to provide a more accessible option for C++ developers who might find attending other international C++ conferences more difficult or financially restrictive, at a time of year where we traditionally see less in-person cpp conferences due to weather, holidays and other restrictions.
