What are the best practices for using unique_ptr in C++?

What are the best practices for using unique_ptr in C++?

When using unique_ptr, always prefer it over raw pointers for resource management. It ensures automatic memory management.

Can you explain how unique_ptr handles ownership?

unique_ptr maintains exclusive ownership of the object it points to. When the unique_ptr goes out of scope, it automatically deletes the object.

What happens if I try to copy a unique_ptr?

You cannot copy a unique_ptr because it is designed to have a single owner. Attempting to copy it will result in a compilation error.

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

Yes, avoid using unique_ptr for objects that need shared ownership. In such cases, consider using shared_ptr instead.

Can unique_ptr be used with arrays?

Yes, you can use unique_ptr with arrays by using unique_ptr<Type[]> syntax, which ensures proper deletion of the array.
