Write a BNF description of the precedence and associativity
rules defined below. Assume the only operands are the names
a,b,c,d, and e.
Precedence
Highest
*, /
+, -
- (unary)
Lowest
=, /=
Associativity
Left to right
Problem 2)
Assume the rules of associativity and precedence for expressions
described in Problem 1.
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)1)2 +
d)3
