C++ Lambda Expressions – From C++98 to C++23 | Udemy

Unlock the full power of callable objects in C++ with this comprehensive journey from traditional C-style callbacks to the very latest C++23 lambda expressions. This course is designed for professional developers who want to move beyond syntax and gain a true, deep understanding of how to write expressive, modern, and highly efficient C++ code.

Start by building a solid foundation with function pointers, exploring the classic C-style approach to callbacks to understand the problems that modern C++ aimed to solve. From there, you will take a deep dive into function objects (functors), learning how to build powerful, stateful operations by creating classes that behave like functions.

Finally, you will progress to lambda expressions. We explore their complete evolution, from the fundamentals in C++11 to the advanced generic and templated features in C++14, C++17, and C++20, all the way to the cutting-edge additions in C++23. By understanding their origins in function pointers and functors, you will see exactly why lambdas are one of the most elegant and powerful features in modern C++.

Whether you’re looking to modernize your codebase, master STL algorithms, or simply write cleaner code, this course will give you a complete and confident command of C++’s callable machinery.
