Complete Modern C++ - Weak Ownership

The video tutorial discusses the use of pointers in programming, starting with raw pointers and their associated risks, such as invalid memory access and double deletion. It then transitions to smart pointers, specifically shared pointers, to manage memory more effectively. However, shared pointers have limitations, particularly with reference counting, which can prevent timely memory release. The tutorial concludes by introducing weak pointers as a solution to these issues, promising a more detailed discussion in the next video.

How can we ensure that a pointer does not lead to a double delete situation?

Why is it important to check if a pointer is still valid before using it?

What modifications are suggested to handle memory management more effectively?
