Match the description of several parts of a classic optimizing compiler in List–I with the names of those parts in List–II
List–I
(a) A part of a compiler that is responsible for recognizing syntax
(b) A part of a compiler that takes as input a stream of characters and produces as output a stream of words along with their associated syntactic categories
(c) A part of a compiler that understands the meanings of variable names and other symbols and checks that they are used in ways consistent with their definitions
(d) An IR-to-IR transformer that tries to improve the IR program in some way
List–II
(i) Optimizer
(ii) Semantic Analysis
(iii) Parser
(iv) Scanner
Answer: A. iii,iv,ii,i — The correct mappings are: (a) Parser for syntax recognition, (b) Scanner for character-to-token conversion, (c) Semantic Analysis for variable meanings, and…
