Questions and Answers

What is one of the problems with using operational semantics for complete formal semantics descriptions?

  • The sequence of state changes is too easy to analyze
  • The storage of a real computer is too small and simple
  • The intermediate language is too high-level
  • The individual steps in the execution of machine language are too small and numerous (correct)

What is the main purpose of operational semantics?

  • To describe the meaning of a statement or program by specifying the effects of running it on a machine (correct)
  • To design high-level programming languages
  • To examine the complete sequence of state changes in a program
  • To analyze the complexity of real computer storage

What is the first step in creating an operational semantics description of a language?

  • Analyzing the complexity of real computer storage
  • Designing an appropriate intermediate language (correct)
  • Creating a high-level programming language
  • Examining the complete sequence of state changes in a program
