Question 16 Synthesized attributes of leaf nodes whose values are determined outside the parse tree are called: terminal attributes meta-attributes full attributes intrinsic attributes Question 17 Static semantics CANNOT be checked at compile time. True False Question 19 A grammar is ambiguous if there are two different derivations for the same sentence. True False Question 20 Match each clue with its corresponding programming language. Object-oriented interpreted scripting language - Originally designed for system programming A. Java B. XSLT . Server-side scripting language C. Python - Smaller, simpler, safer than C++ D.C - Specifies transformation on XML E. PHP Question 21 To users and language implementors, probably the most important characteristic of operational semantics for it to be effective in describing language semantics is: ensuring descriptions are complex and formal keeping descriptions simple and informal rigorously defining functional domains and ranges including formal mathematics Question 10 A grammar is unambiguous if every sentence has exactly one derivation. True False Question 11 Which of these is NOT an example of a programming environment? UNIX NetBeans VisualStudio von Neumann Question 12 In the context of formal languages, the acronym BNF stands for: Brain Natriuretic Factor Backus-Naur Form British National Formulary Big Name Fan Question 15 The most abstract approach to semantics specifications discussed by Sebesta in our textbook is: denotational semantics axiomatic semantics dynamic semantics static semantics
