What is a unique pointer in C++?
A unique pointer is a smart pointer in C++ that ensures a single ownership of a dynamically allocated object.
How does it differ from a regular pointer?
Unlike regular pointers, unique pointers automatically manage memory and delete the object when it goes out of scope.
Can I transfer ownership of a unique pointer?
Yes, you can transfer ownership using the std::move
function, which allows one unique pointer to take over the resource.
Are there any downsides to using unique pointers?
The main downside is that you cannot copy unique pointers; they can only be moved, which may require careful management.
