What is the primary purpose of lexical analysis in a compiler?

• To generate optimized machine code

• To convert high-level source code into assembly language

• To identify and categorize the basic language elements in the source code

• To perform syntax checking

Which phase of the compiler is responsible for checking whether the program adheres to the language's syntax rules?

• Semantic Analysis

• Lexical Analysis

• Code Generation

• Syntax Analysis

What does a parser do in the context of a compiler?

• Checks for syntax errors and constructs a parse tree

• Executes the program

• Transforms the source code into intermediate code

• Generates optimized machine code

Which of the following parsing techniques is more powerful and can handle a wider class of grammars?

• LR(0) parsing

• LL(1) parsing

• LALR(1) parsing

• LR(1) parsing

Which phase of the compiler is responsible for optimizing the intermediate code to improve program efficiency?

• Lexical Analysis

• Code Optimization

• Semantic Analysis

• Code Generation

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

• It keeps track of identifiers and their associated attributes.

• It stores the source code in a compact form.

• It maintains a list of reserved keywords.

• It generates machine code from the source code.

Which phase of the compiler generates assembly code or machine code from the intermediate representation?

• Syntax Analysis

• Code Optimization

• Semantic Analysis

• Code Generation

What is the primary goal of code optimization in a compiler?

• Generating a human-readable intermediate representation

• Reducing the size of the source code

• Transforming the source code into machine code

• Improving the efficiency of the generated code

Which of the following is NOT part of the compiler's frontend?

• Lexical Analysis

What is the runtime environment in the context of a compiled program?

• The phase of the compiler that generates machine code

• The set of hardware and software resources available during program execution

• The phase of the compiler that performs code optimization

• The process of converting source code into assembly code
