/*
   This program demonstrates how precedence of operators
    can affect the results of calculations.  (Refer to a
    textbook for charts showing the specific rules of
    precedence for all of the C++ operators.)  By using
    parentheses, the same expression can be made to
    produce a variety of answers.
