What type of operator does the 'iterator' overload to act as a pointer?

== -> ++ *

Correct Answer:

Explanation:

The 'iterator' overloads the '*' operator to act as a pointer. This option is correct because 'iterator' is a type of smart pointer in C++, and by overloading the '*' operator, it allows for dereferencing of the iterator and accessing the underlying object it points to. Option A The '==' operator is used for equality comparison and has nothing to do with the 'iterator' acting as a pointer. Option B: The '->' operator is used for member access on a pointer and does not directly relate to the 'iterator' acting as a pointer. Option C: The '++' operator is used for incrementing a value and is not directly related to the 'iterator' acting as a pointer.
