Question

Consider the following two sets:Set X: P. Lexical Analyzer, Q. Syntax Analyzer, R. Intermediate Code Generator, S. Code OptimizerSet Y: 1. Abstract Syntax Tree, 2. Token, 3. Parse Tree, 4. Constant FoldingWhich one of the following options is the CORRECT match from Set X to Set Y?

Accepted Answer

Correct Answer: (B) P-2; Q-3; R-1; S-4Concept -- Phases of a Compiler: Each phase of a compiler produces a specific output.The Lexical Analyzer (P) reads the source program and produces tokens (2) as its output. Each token represents a lexical unit such as an identifier, keyword, or operator.The Syntax Analyzer (Q) takes the token stream and builds a parse tree (3) that represents the syntactic structure of the program according to the grammar.The Intermediate Code Generator (R) takes the parse tree and produces an intermediate representation such as an Abstract Syntax Tree (1) or three-address code.The Code Optimizer (S) performs optimizations such as constant folding (4), which evaluates constant expressions at compile time, along with other transformations to improve efficiency.
