Question 66
What type of translation grammar associates semantic evaluation rules directly with productions in Context-Free Grammars?
SDDs attach attributes and semantic evaluation rules directly to context-free grammar production rules.
What type of translation grammar associates semantic evaluation rules directly with productions in Context-Free Grammars?
SDDs attach attributes and semantic evaluation rules directly to context-free grammar production rules.
Inherited attributes in a parse tree node can be evaluated from attribute values of which nodes?
Inherited attributes are computed from a node's parent and/or its siblings in the parse tree.
Synthesized attributes in a parse tree node are computed from attribute values of which nodes?
Synthesized attributes at a node are computed exclusively from attribute values at its children nodes.
Which attribute evaluation order corresponds strictly to an S-attributed definition?
S-attributed definitions use only synthesized attributes, enabling bottom-up post-order evaluation during LR parsing.
What is 'Type Checking' in semantic analysis?
Type checking ensures type safety by checking operator-operand compatibility across all constructs.
