What are some unique examples of pointer usage in programming?

Unique pointers are a smart pointer type in C++ that manage the lifetime of dynamically allocated objects. One unique example is using a unique pointer to implement a factory pattern, where each object created by the factory is owned by a unique pointer.

Can you give me another example?

Sure! Another example is using unique pointers in a data structure like a binary tree, where each node can have unique ownership of its children, ensuring proper memory management.

How do unique pointers help with memory management?

Unique pointers automatically deallocate memory when they go out of scope, preventing memory leaks and ensuring that resources are properly released.

Are there any drawbacks to using unique pointers?

Yes, one drawback is that unique pointers cannot be copied, only moved. This can complicate certain designs where shared ownership is needed.
