Clarification on exercise 7.2

[MarkReid]

Can I just clarify something on exercise 7.2? What does it mean by optional BOOL?

If I make a print method that takes an argument does that mean I also need to make a print method that doesn't take any?

Thanks

You can just have a single print method that take a BOOL argument and if that argument is YES it reduces the fraction.
