Questions and Answers

What is the primary purpose of abstraction in object-oriented programming?

  • To partition a program into individual components
  • To deal with complexity by focusing on essential features and suppressing others (correct)
  • To define the behavior of objects through inheritance
  • To encapsulate implementation details within objects

    • Which of the following statements about encapsulation is true?

  • It is the process of creating a hierarchy of classes through inheritance
  • It is the act of partitioning a program into individual components
  • It separates the behavior of an object from its implementation
  • It focuses on the implementation that gives rise to the behavior of an object (correct)

    • What is modularity in object-oriented programming?

  • The practice of hiding implementation details within objects
  • The process of creating a hierarchy of classes through inheritance
  • The act of partitioning a program into individual components with well-defined boundaries (correct)
  • The process of focusing on the essential characteristics of an object
