Which of the following operations do forward iterators have?
A) Overloaded operator+ to add an int value to the iterator to move the place the iterator points forward by the argument number of elements.
B) Overloaded operator* to multiply the iterator by an int value to move the place the iterator points by a number of elements equal to the argument.
C) Overloaded operator++ to move the place the iterator points forward by one element.
D) Overloaded operator-- to move the place the iterator points backward by one element.

Forward iterators support the operation of moving the iterator forward by one element, which is achieved through the overloaded operator++. They do not support arbitrary addition or subtraction (like with operator+ or operator--) nor multiplication of the iterator by an integer.
