Understanding Program Compilation

What is the primary purpose of lexical analysis in the compilation process?

• To convert source code into tokens for further processing.

• To generate machine code directly from the source code.

• To perform syntax checking of the source code.

• To optimize the source code for faster execution.

Which of the following is NOT a technique used in lexical analysis?

• Symbol table management

• Token generation

• Syntax parsing

• Lexeme identification

What does a syntax tree represent in the context of syntactic analysis?

• A list of all variables used in the source code.

• A visual representation of the execution flow of a program.

• A hierarchical representation of the grammatical structure of source code.

• A summary of the functions defined in the code.

In a syntax tree, what do the leaves typically represent?

• The semantic actions associated with the syntax.

• The non-terminal symbols of the language.

• The terminal symbols or tokens of the language.

• The grammar rules of the language.

What is the role of semantic analysis in the compilation process?

• Semantic analysis translates the code into machine language.

• Semantic analysis optimizes the performance of the code during compilation.

• Semantic analysis ensures the correctness of meaning in the code during compilation.

• Semantic analysis checks for syntax errors in the code.

Which phase of compilation is responsible for code optimization?

• Code generation phase

• Optimization phase

• Lexical analysis phase

• Parsing phase

What is the output of the code generation phase?

• Source code

• Assembly code

• Machine code or intermediate code

• High-level programming language

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

• To manage memory allocation for variables.

• To optimize the execution speed of the program.

• The purpose of a symbol table in a compiler is to manage and store information about identifiers in the source code.

• To store the source code in a compressed format.

Which of the following best describes intermediate code?

• A representation of a program that is between high-level source code and machine code.

• A graphical representation of a program's flow.

• A high-level programming language that is not compiled.

• A type of machine code that is directly executable by the CPU.

What is the main goal of the compilation process?

• To debug the source code for errors.

• To optimize the performance of the source code.

• To translate high-level source code into machine code.

• To convert machine code into high-level source code.
