|
|
|
be evaluated only if the definition is L-attributed
|
|
|
be evaluated only if the definition has synthesized attributes
|
|
|
never be evaluated
|
Question 18 Explanation:
L-Attributed grammar can able to inherits either inherited attributes (or) synthesized attributes.
L-Attributed definitions are a class of syntax directed definitions whose attributes can be evaluated by a single traversal of the parse-tree.
