Favor copy semantics unless you will be developing a “intelligent pointer”. Worth semantics is the simplest to purpose about and what the typical-library facilities hope.

Don’t Homepage let this tempt you into returning an owning Uncooked pointer; this is the slight drawback as compared to the key robustness gain sent by the proudly owning sensible pointer.

In terms of linked here we can notify, these principles bring about code that performs at the same time or better than older, additional typical techniques; they are meant to Stick to the zero-overhead principle (“Everything you don’t use, you don’t purchase” or “once you use an abstraction mechanism properly, you receive a minimum of nearly as good performance as for those who experienced handcoded making use of lessen-level language constructs”).
