And it is not an error to put assignments in conditionals, or not
place parentheses to clarify operator precedence, etc. It is a
warning; the compiler is telling you that it is unclear what you
are trying to do, and you should check to make sure that this is
what you want to do (and let the compiler know by making your
intentions clear). For some of us this is helpful. The compiler
writers try to help protect programmers against common mistakes.
If you don't like the warnings you are free to turn them off.
