Questions and Answers

What is the main purpose of a language processing system in compiler design?

  • To ensure that the computer's operating system is compatible with the programming language being used
  • To optimize the performance of the computer's hardware
  • To provide a user-friendly interface for writing programs in a high-level language
  • To translate high-level programming languages into binary code that can be executed by the computer's hardware (correct)

    • What is the role of a preprocessor in the language processing system?

  • To provide a user-friendly interface for writing programs in a high-level language
  • To optimize the performance of the computer's hardware
  • To include all necessary header files and evaluate macros (correct)
  • To generate the binary code that can be executed by the computer's hardware

    • What is the purpose of using macros in a programming language?

  • To ensure that the computer's operating system is compatible with the programming language being used
  • To improve the performance of the computer's hardware
  • To provide a user-friendly interface for writing programs in a high-level language
  • To automate frequently used sequences of code or enable more powerful abstraction (correct)
