Summary  
This chapter covers different smart pointer types—shared, unique, and weak—detailing their ownership semantics, construction methods, copyability, performance and memory overhead characteristics.  

General domain of usage  
Memory management

What happens when multiple `std::shared_ptr` instances share ownership of the same object, and all of them go out of scope?

Which of the following is true about `std::unique_ptr`?  

Why would you use a `std::weak_ptr` instead of a `std::shared_ptr`?  

Unlock the power of memory management. Designed seasoned programmers, this course provides a deep dive into one of the most crucial aspects of modern development and revise about pointers and references. With Smart Pointers, you'll learn how to effectively manage memory allocation and deallocation, avoiding common pitfalls like memory leaks and dangling pointers. Our expert instructors guide you through the intricacies of unique_ptr, shared_ptr, and weak_ptr, empowering you to write safer and more robust code.

Understand the fundamentals of pointers, how they interact with memory, and why dynamic allocation is crucial. Explore the challenges of manual memory management and how smart pointers solve common issues like memory leaks and dangling pointers.

Learn how std::unique_ptr manages exclusive ownership and automates memory deallocation. Explore creation, movement, and best practices for passing unique pointers, along with key methods and real-world applications for safer, more efficient code.

Explore shared pointers, investigating their functionality, benefits, real-world applications in programming and what sets unique pointers apart.

Explore weak pointers, comprehending their nature, creating and utilizing them effectively, resolving circular references through weak pointers, and examining key functions associated with weak pointers.

Learn how to use custom deleters for smart pointers, real-world smart pointer applications, performance considerations, and a detailed comparison of shared, unique, and weak pointers.
