Complete Modern C++ - Circular References

The video tutorial discusses the use of weak pointers in C++ to solve issues related to circular references and memory leaks. It begins by setting up two classes, Employee and Project, and demonstrates the initialization of raw pointers. The tutorial then transitions to using smart pointers, highlighting the problem of circular references when shared pointers are used. The solution is presented by introducing weak pointers, which help in breaking the circular reference chain, ensuring proper memory management. The video concludes with an implementation of weak pointers, showing that destructors are invoked correctly, indicating no memory leaks.

What are the implications of having two shared pointers pointing to each other?

How does the weak pointer prevent memory leaks in the example provided?

In what scenarios would you prefer to use a weak pointer over a shared pointer?

Summarize the process of initializing a weak pointer with a shared pointer's control block.
