When should I use unique pointers in C++?

When should I use unique pointers in C++?

You should use unique pointers when you want to ensure that a resource has a single owner, preventing memory leaks.

Can you explain how unique pointers differ from shared pointers?

Sure! Unique pointers allow only one owner, while shared pointers can have multiple owners, managing reference counts.

Are there any performance benefits to using unique pointers?

Yes, unique pointers are generally more efficient than shared pointers because they don't require reference counting.

What happens if I try to copy a unique pointer?

If you try to copy a unique pointer, it will result in a compilation error since unique pointers cannot be copied.

Can I convert a unique pointer to a shared pointer?

Yes, you can convert a unique pointer to a shared pointer using std::move to transfer ownership.
