19. Which paradigm uses recursion and immutability as core concepts? — Functional
20. Which programming paradigm is characterized by a focus on 'what' needs to be computed rather than 'how'? — Declarative Programming
21. Code optimization aims to: — Improve the efficiency (speed, size) of the intermediate or target code.
22. What is a common model for imperative programming? — State transformation
23. Binding a variable to a memory location typically happens at which binding time? — Compile-time or run-time
24. The association of a variable name with its scope is an example of binding that occurs at: — Compile-time or interpretation-time
25. Intermediate code generation typically occurs after which stage? — Semantic analysis
26. What is the final stage of a typical compiler? — Code generation
27. Type checking is typically performed during which translation stage? — Semantic Analysis
28. Which translation stage deals with the structure and grammar of the code? — Syntax Analysis

39. What is 'syntax' in the context of programming languages? —
40. In the context of programming language translation, what is 'intermediate representation'? — An abstract form of the program that is easier to optimize and translate.
41. Binding refers to the association of a name with a thing. What is 'binding time'? — The time at which a given binding is made.
42. In functional programming, what is a key characteristic of functions? — They always return the same output for the same input.
43. What is the purpose of the 'semantic analyzer' in a compiler? — To check for type consistency and other meaning-related errors.
44. What is the primary goal of the 'code generator' stage? — To produce target machine code or intermediate code.
45. What is the primary role of a 'compiler'? — To translate source code from one language to another (e.g., high-level to machine code).
46. What is the role of a 'debugger' in a programming environment? — To help programmers find and fix errors in their code.
