Our friendly jsmith answered your question directly and exactly -- it has everything to do with your question, as it is the only available correct answer.
Why exactly you would find a line of code like you listed depends entirely upon the range of values that n may take. (It also presumes a valid line of code.)
To be honest, I don't think he was rude. When he said this has nothing to do with my quesiton, I think he referred back to when he said I'm not sure I can understand the logic of the test.
I'm not sure I can understand the logic of the test but this has nothing to do with my question.
(He can't understand the logic but he's saying that that has nothing to do with his 'question' being What does it[the '&' sign] mean?)
please read my replay again. I meant exactly the opposite of what you think.
What I meant is that the logic of the test has nothing to do with my question. Off course that the answer of jsmith was relevant to my question as this is the test that is being done.
Sorry if I have offended you or jsmith in ANY way.
