Answer 1

Access qualifiers simply apply to the code that follows until the next qualifier. There is no restriction on the number or order of such qualifiers.

It is generally not necessary to repeat the same access qualifier in a class, and doing so is likely to confuse the reader. They also may have an effect on the layout of a class, since data members following the same qualifier must be laid out in the order they are declared, but there is no such restriction between qualifiers.
