Assume the following rules of associativity and precedence for expressions:
precedence
highest
- (unary), (prefix) ++, (prefix) --
(postfix) ++, (postfix) --
+, *, & , mod
-, /, not
< , =, > , ! =
=, +=, *=, /=
and
or, xor
lowest
associativity
left to right
show the order of evaluation of the following expressions by parenthesizing all subexpressions and placing a superscript on the right parenthesis to indicate order. for example, for the expression a * b + c / d the order of evaluation would be represented as
((a * b)ˆ1 + c)ˆ2 / d)ˆ3
also rewrite the expression where there are no precedence rules and the statement is given right to left associativity, for example for the same problem above
d / c + b * a
a. a * b - 1 + c
b. a * (b - 1) / (++c++) mod d
c. (a - b) / c & (d * e / a - 3)
d. -a or c = d and e
e. a > b xor c or d < = 17
f. -a + b

Which of the following statements is false? a. a class can directly inherit from class object. b. if the class you're inheriting from declares instance variables as private, the inherited class can access those instance variables directly. c. a class's instance variables are normally declared private to enforce good software engineering. d. it's often much more efficient to create a class by inheriting from a similar class than to create the class by writing every line of code the new class requires.
