C++ Standard Template Library in Practice - Shared Pointers

The video tutorial explains the use of smart pointers in C++, focusing on unique, shared, and weak pointers. Unique pointers ensure exclusive ownership of resources, while shared pointers allow multiple ownerships with automatic memory management. Weak pointers provide non-owning references to shared pointers, useful for checking object existence without affecting its lifetime. The tutorial includes practical examples demonstrating the creation, conversion, and usage of these pointers, highlighting the importance of reference counting and scope management.

What is the primary purpose of a unique pointer in resource management?

Explain how a shared pointer manages the memory of an object.

How does the reference count of a shared pointer affect its lifetime?

What is the difference between a shared pointer and a weak pointer?

Describe the process of converting a weak pointer to a shared pointer.

Why is it important to check if a weak pointer can be locked?

What happens to a shared pointer when it goes out of scope?
