Complete Modern C++ - std::shared_ptr

The video tutorial explains the concept of shared pointers in C++ programming. It highlights the limitations of unique pointers, which do not allow sharing, and introduces shared pointers as a solution. Shared pointers enable multiple objects to share ownership of a pointer, maintaining a reference count to manage memory. The tutorial covers practical examples, demonstrating how to replace unique pointers with shared pointers and explaining the reference counting mechanism. It also discusses methods like reset and checking for valid pointers. The session concludes with a brief mention of weak pointers, to be covered in the next lecture.
