Don't check with Other individuals to debug your broken code with no supplying a hint what kind of issue they ought to be attempting to find. Publishing some hundred strains of code, expressing "it would not operate", will get you ignored.

(A person may well surprise: if this A great deal code is necessary to deal with just one source accurately, Imagine if my class manages more than one?

perform that swaps two objects of a class, member for member.
