C++: Unique Pointer vs Shared Pointer
An example of an AI chatbot conversation about C++ smart pointers: unique vs shared.
What is the difference between unique_ptr and shared_ptr in C++?
Unique pointers (unique_ptr) are exclusive ownership pointers, while shared pointers (shared_ptr) allow shared ownership.
When should I use unique_ptr instead of shared_ptr?
Use unique_ptr when you want sole ownership and no need for shared access, which is more efficient.
Can shared_ptr lead to memory leaks?
Yes, if there are circular references between shared_ptrs, it can lead to memory leaks.
How do I convert a unique_ptr to a shared_ptr?
You can use std::move to transfer ownership from unique_ptr to shared_ptr, but ensure it's valid.
