NettetA linked list is the simplest case of a collection of objects that refer to each other. The objects are called nodes, and the logical references are links between the nodes. In C++ code the links can be pointers or indices or hash values or names, or even pairs of names, whatever serves best to identify the link relation. Nettet16. mar. 2024 · unique_ptr stores one pointer only. We can assign a different object by removing the current object from the pointer.
