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`.
