Is there a difference between "claro" and "por supuesto"?

Question

Both "claro" (or "claro que sí") and "por supuesto" appear to be used to say 'of course' in one way or another.Are there any differences in how they are used? Is one formal and the other informal? Or are they interchangeable?

Answer 1

This really depends on the region in where you're saying it. From what I have been taught at university, they both mean "of course" or phrases around that. They can be used in formal and informal situations.
