Question: 1 / 565

How is the postfix increment operator differentiated from the prefix increment when overloading?

It has a return type of void

It takes an additional 'int' parameter

The postfix increment operator is unlike the prefix increment operator because it takes an additional 'int' parameter. This is necessary because the postfix operator returns a copy of the original value before it is incremented, whereas the prefix operator increments the value before returning it. The other options are incorrect for various reasons A is incorrect because the return type is not what differentiates the operators, C is incorrect since neither operator returns a constant, and D is incorrect because both operators can be defined inside or outside of the class.
