Syllabus

Introduction

In this module, we will introduce the course structure, roadmap, and objectives. You will gain an understanding of how mastering C++ callable entities like function pointers, function objects, and lambdas will enhance your coding proficiency. This section will set the foundation for exploring the power of C++ features from C++98 to C++23.

Function Pointers

In this module, we will cover the fundamentals of function pointers, from basic syntax to advanced examples. You’ll learn how to use function pointers for flexible, dynamic execution and understand callbacks and pointers to member functions in the context of C++ programming. This section will equip you with essential skills for implementing responsive, event-driven programs.

Function Objects

In this module, we will explore function objects (also known as functors), comparing them with function pointers. We will show you how to craft efficient, reusable callable entities and teach techniques to refine these objects for improved performance. By the end of this section, you'll be equipped to leverage the full potential of function objects.

Lambda Features in C++11

In this module, we will dive deep into the core features of C++11 lambdas. You’ll learn how to use capture lists, different capture methods (by reference, by value), and lambda conversions. With examples of Immediately Invoked Function Expressions (IIFE), you will be able to use lambdas effectively to create clean and compact code.

Lambda Features in C++14 and C++17

In this module, we will explore how C++14 and C++17 enhanced lambda expressions. You’ll learn about generic lambdas, generalized lambda captures, and constexpr lambdas for performing compile-time computations. These advanced features will take your lambda skills to the next level, making your code more flexible and efficient.

Lambda Features in C++20

In this module, we will focus on the advancements introduced in C++20, including implicit capture of this in lambdas, template type parameters, and constraints with concepts. These new features allow you to write more elegant and type-safe lambda expressions, improving both the performance and maintainability of your code.

Lambda Features in C++23

In this module, we will explore the cutting-edge lambda features introduced in C++23. You will learn how to implement static lambdas, apply recursive lambda patterns, and add attributes to lambdas for optimization. This section will help you harness the latest tools to write more powerful and efficient lambdas.
