Answer:
A syntax-directed definition (SDD) is a context-free grammar with attributes attached to grammar symbols and semantic rules attached to the productions. The semantic rules define values for attributes associated with the symbols of the productions.
with attributes attached to grammar symbols and semantic rules attached to the productions.
Explanation:
A SYNTAX-DIRECTED DEFINITION is a context-unfastened grammar in which. every grammar image X is related to finite units of values: the synthesized attributes of X and the inherited attributes of X, every manufacturing A is related to a finite set of expressions of the form.
It is used for semantic evaluation and SDT is largely used to assemble the parse tree with Grammar and Semantic motion.
In Grammar, want to determine who has the best precedence may be finished first and In semantic motion, will determine what kind of motion finished via way of means of grammar.
