Which of these operations does an iterator class typically have?

a) Overloaded increment and decrement operators to move the next node forward or
backward, respectively.
b) Overloaded binary operator* to multiply two iterators.
c) Overloaded operator== to compare iterators and return true if the iterators
point to the same item.
d) Overloaded operator&& to perform logical operations on two iterator.
e) Overloaded operator!= to compare iterators and return false if the iterators do
not point to the same item.
f) Overloaded unary operator* that returns the item to which the iterator points.

Parts a) c) e)and f) are correct.
