In the typical singly linked list node declaration in C++, what is the type of the link member?

Explanation:
The link member is a pointer to the next node in the list, so it must be a pointer to the same node type (nodeType*). This self-referential type allows each node to point to another node of the same structure, enabling the chain to be traversed from one node to the next. Using a plain int, char, or even a void* would store data or a generic pointer, not the address of the next node, and would break the clean, typed linkage required to walk the list. A nodeType* keeps the type information intact and lets you safely dereference to reach the next node.
