Optional Arguments C# Need Help!

Question

I don't know how why the outputs in Optional Arguments from C# are like they are.

Answer 1

I'm Not sure I mean the example "static int Pow" and why the result gets 6.

Answer 2

Can you post the code of the example. I do not understand your question yet but I think it is a good question.

Answer 3

do you mean like public func(string mystr, int i = null) ? as in why it's set up that way?
