Functional Programming in C++

What do ranges, error handling, and I/O have in common? A single functional concept that simplifies complex C++ systems.

Functional Programming in C++
#1about 3 minutes

Understanding functional programming principles in C++

Functional programming is a declarative style that eliminates state to reduce bugs, and C++ allows combining its benefits with imperative performance.

#2about 4 minutes

Building lazy data pipelines with C++20 ranges and views

Use `std::ranges` and views like `transform` and `filter` to create lazy, state-free data processing pipelines that avoid intermediate allocations.

#3about 8 minutes

Solving complex problems with advanced range adaptors

Leverage powerful range adaptors like `cartesian_product` for combinations and `chunk_by` for splitting sequences based on a predicate.

#4about 6 minutes

Creating composable error handling with `std::expected`

Model failures as values using `std::expected` to build clear, functional error handling pipelines with `transform` and `and_then`.

#5about 4 minutes

Separating IO from computation using deferred actions

Isolate side effects by composing IO operations as declarative actions, a pattern that mirrors the upcoming C++26 senders and receivers framework.

#6about 2 minutes

Understanding monads as a unifying composition pattern

Recognize that ranges, `std::expected`, and IO actions are all monads, sharing a common interface for composition with `transform` and `and_then`.
