Beyond new and delete: to Weak Pointer

In the previous article , we left one case untouched: the transition from raw pointers to weak_ptr. That's exactly what we'll dive into today. Use shared_ptr when multiple parts of your system need to keep an object alive, and you can't predict which part will outlive the others. But shared_ptr has a fatal flaw: cyclic references. When two shared_ptrs point to each other, neither can die. They hold each other hostage forever. The result? A memory leak that never gets cleaned up. Let me break it
