Compiler and Lexical Analysis Quiz 2

What is the primary function of a compiler?

• To execute the source code directly

• To debug the source code

• To translate source code into target code

• To optimize the source code

Which phase of the compiler is responsible for lexical analysis?

• Synthesis phase

• Code generation phase

• Semantic analysis phase

• Analysis phase

What does a preprocessor do?

• Generates machine code

• Processes macros and includes files

• Optimizes the code

• Handles semantic errors

What is the purpose of the semantic analysis phase?

• To optimize the code

• To generate intermediate code

• To gather type information and check for semantic errors

• To check for syntax errors

Which of the following is NOT a function of the lexical analyzer?

• Performing syntax analysis

• Skipping white spaces and comments

• Producing tokens

• Reading input characters

What is a token in the context of lexical analysis?

• A sequence of characters that forms a meaningful word

• A type of error in the source code

• A command for the parser

• A data structure for storing identifiers

What is the role of the symbol table in a compiler?

• To store the source code

• To record identifiers and their attributes

• To generate machine code

• To optimize the code

Which of the following is a property of regular expressions?

• They are not used in compilers

• They cannot be used in lexical analysis

• They can describe infinite languages

• They can only describe finite languages

What does NFA stand for in the context of finite automata?

• Non-Deterministic Finite Automaton

• Non-Functional Automaton

• Non-Formal Automaton

• Non-Finite Automaton

What is the purpose of code optimization in a compiler?

• To debug the code

• To enhance the performance of the generated code

• To translate the code into machine language

• To improve the readability of the code
