C++ Tutorial: Lambdas & Functional
Lambda expressions, captures, std::function, std::bind, and functional programming patterns in C++.
Inline functions, anywhere
Lambdas (C++11) let you write functions inline — no need to name them. They're the key to making STL algorithms expressive and building functional-style data pipelines.
Every `sort`, `transform`, `find_if` you've written already used lambdas. Now let's understand them deeply.
What you'll learn in this C++ lambdas & functional tutorial
This interactive C++ tutorial has 5 hands-on exercises. Estimated time: 20 minutes.
- Lambda basics — Lambda syntax:
- Captures — access outer variables — Lambdas can capture outer variables:
- std::function — store any callable — `std::function<returnType(params)>` can hold ANY callable — lambda, function pointer, or functor:
- Returning lambdas — Functions can return lambdas — this creates closures, encapsulating state:
- Build a function pipeline — No starter code.
