Which statement is false?
a. Based on whether an operator is implemented as a member function or as a non-member function, the operator is used differently in expressions. b. When an operator function is implemented as a member function, the leftmost (or only) operand must be an object (or a reference to an object) of the operator's class. c.

Another reason why you might choose a non-member function to overload an operator is to enable the operator to be commutative.
