Questions and Answers

Which of the following statements about inheritance in object-oriented programming is true?

  • Inheritance allows programmers to create new classes based on existing ones, with the exception of constructors, destructors, overloaded operators, and friend functions. (correct)
  • Inheritance allows programmers to create new classes that can only inherit constructors and destructors from existing ones.
  • Inheritance allows programmers to create new classes that have the exact same implementation as existing ones.
  • Inheritance allows programmers to create new classes that are completely independent of existing ones.

What is the purpose of inheritance in object-oriented programming?

  • To create classes that are completely independent of existing classes.
  • To create classes that can only inherit constructors and destructors from existing classes.
  • To create classes that have the exact same implementation as existing classes.
  • To create classes that are built upon existing classes and maintain the same behaviors. (correct)

What is the difference between prototype-based inheritance and class-based inheritance?

  • Prototype-based inheritance is based on classes, while class-based inheritance is based on objects.
  • Prototype-based inheritance is more commonly used in object-oriented programming languages.
