When should I use unique_ptr in C++?

When should I use unique_ptr in C++?

You should use unique_ptr when you want to ensure that a resource is owned by a single pointer, preventing memory leaks.

Can you explain the advantages of using unique_ptr over raw pointers?

Sure! unique_ptr automatically manages memory, ensuring that the resource is deleted when the unique_ptr goes out of scope, which helps prevent memory leaks.

Are there any situations where I shouldn't use unique_ptr?

Yes, if you need shared ownership of a resource, you should use shared_ptr instead. unique_ptr is best for exclusive ownership.

How does unique_ptr handle resource transfer?

unique_ptr allows resource transfer through move semantics, enabling you to transfer ownership without copying the resource.

Can unique_ptr be used with arrays?

Yes, you can use unique_ptr with arrays by using unique_ptr<Type[]> to manage dynamic arrays.
