Expert Solution & Answer
Chapter 3, Problem 11RQ
Explanation of Solution
Order of evaluation of attributes determined for trees of a given attribute grammar:
It is basically determined by the requirement on demand and dependency in the code, than order in which they are present. Knowing the static semantic rules of any language is must for any designer to work over for compiler.
Difficulty is in size and complexity of description of complete set of syntax and semantics of a real contemporary language...
