What does an iterator typically simulate?

Template instantiation

Pointer operations

An iterator typically simulates pointer operations. An iterator is a pointer-like object that is used to iterate over a sequence of elements, and thus, it performs pointer operations such as dereferencing and incrementing. Template instantiation (A) is not an accurate choice, as iterators are not related to templates. Dynamic memory allocation (C) is also incorrect as iterators do not allocate memory, but rather traverse over existing data structures. Recursive function calls (D) are not related to iterators as they are a way of solving problems by breaking them down into smaller subproblems.
