Unique pointers (unique_ptr) are exclusive ownership pointers, while shared pointers (shared_ptr) allow shared ownership.

You

When should I use unique_ptr instead of shared_ptr?

MagicBuddy

Use unique_ptr when you want sole ownership of a resource, which can improve performance and reduce overhead.

You

Can you give an example of when to use shared_ptr?

MagicBuddy
MagicBuddy

Use shared_ptr when multiple parts of your program need to share ownership of an object, like in a graph structure.

😀
You

Are there any downsides to using shared_ptr?

MagicBuddy
MagicBuddy

Yes, shared_ptr has overhead due to reference counting and can lead to circular references if not managed properly.
