A reference parameter allows the method to directly modify the value of the parameter passed to it. An output parameter is a type of reference parameter specifically designed for returning a value from a method. Global variables would not necessarily be the best option because they can lead to unexpected behavior and make it more difficult to track down bugs. Optional parameters are useful when you want to provide a default value but still allow the user to override it, but they do not allow the method to modify the parameter.
