Functional Programming in C++: Pure Functions, Composition, and Ranges

Writing robust and maintainable C++ often requires moving beyond object-oriented paradigms. This course introduces you to the power of functional programming (FP) principles applied directly within the C++ ecosystem, leading to clearer data flow and reduced side effects. By the end of this course, you will be able to refactor existing imperative C++ code into a modern functional style, leveraging powerful language features for effective data processing. What you'll learn: * Understand the core tenets of functional programming, including immutability, purity, and the avoidance of side effects in C++. * Practice using C++ lambdas and function objects as higher-order functions for flexible behavior and composition. * Apply function composition and currying patterns to build complex logic from small, reusable components. * Master the C++ Ranges library to efficiently process sequences and transform data pipelines without manual iteration. * Configure effective error handling using standard library types like std::optional and std::variant instead of exceptions or raw pointers. * Build clean, testable code by separating data transformation logic from side effects and input/output operations. The course begins by defining foundational FP concepts and immediately applying them using modern C++ syntax. We then progress through practical exercises focused on implementing composition, leveraging higher-order functions, and using the Ranges library for complex data manipulation. This course is designed for beginner C++ developers or those familiar with basic C++ syntax who want to learn a modern and highly effective coding paradigm.
