The Imperatives Must Go! [Functional Programming in Modern C++] - Victor Ciura - CppCon 2022

Discover how to bring functional programming principles to modern C++ development, exploring topics like composition, higher-order functions, and monads to create more concise and expressive code.

Key takeaways

Functional programming is not limited to specific languages, but is a style of programming that can be applied to any language.
C++ is a multi-paradigm language that has already been influenced by functional programming.
Functional programming is about composition of functions, rather than sequencing of statements.
Lifting functions allows for the creation of higher-order functions that can be composed together.
Monads are a way to combine multiple operations together in a single function.
The idea of boxing values, such as using optional vs. unique_ptr, can help with function composition.
The FMAP concept allows for the transformation of a function from one type to another.
Functional programming can be used to create more concise and expressive code.
The use of higher-order functions, such as when_all and when_any, can simplify code.
The concept of piping functions together, similar to the Unix pipe, can be used in C++.
The use of type constructors, such as optional and vector, can help with function composition.
Functional programming can be used to create more rigorously designed code.
The use of monads can help with error handling and exception handling.
The concept of Schrödinger’s cat programming refers to the idea of dealing with uncertainty and uncertainty principles in programming.
C++ has become a more functional programming language over time, with the introduction of features like ranges and coroutines.
