Question

14. (15 points) Assume the following rules of associativity and precedence for expressions Precedence Highest *, /, not , &, mod (unary) 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 c)12+ d) 3 a* a * b-1+c b. a* (b - 1) / c mod d c. (a - b) / c & (de/a - 3) d. -a or c- d and e e. a > b xor c or d

Explanation / Answer

Answers are given below taken into consideration Highest to lowest priority and associativity from left to right.

a) (((a * b)1 - 1)2 + c)3

b) (((a * (b - 1)1 )2 / c)3 mod d)4

c) (((a - b)1 / c)2 & (((d * e)3 / a)4 - 3)5 )6

d) (-a or (c = (d and e)1 ) 2)3

e) (((a > b)1 xor c)2 or (d <= 17)2 )3

f) (-a + b)1
