What is std::unique_ptr in C++?

Can you explain what std::unique_ptr is in C++?

Sure! std::unique_ptr is a smart pointer in C++ that manages the lifetime of a dynamically allocated object.

How does it differ from a regular pointer?

Unlike regular pointers, std::unique_ptr ensures that there is only one owner of the object, preventing memory leaks.

What happens if the unique_ptr goes out of scope?

When a std::unique_ptr goes out of scope, it automatically deletes the associated object, freeing the memory.

Can I transfer ownership of a unique_ptr?

Yes, you can transfer ownership using std::move, which allows another unique_ptr to take over the resource.
