Questions and Answers

Why are encapsulation and data hiding important concepts in object-oriented systems?

  • They allow for more efficient use of memory
  • They ensure that objects can only be accessed by specific procedures or functions
  • They protect the internal state of an object from being modified by unauthorized code (correct)
  • They prevent multiple instances of an object from being created
  • In the context of system design, what is a benefit of using inheritance in object-oriented systems?

  • It improves the performance of the system by minimizing memory usage
  • It simplifies the debugging process by eliminating any runtime errors
  • It reduces the need for writing new code by allowing for code reuse (correct)
  • It leads to a more modular and less interconnected system design
  • What is a key difference between procedural and object-oriented systems?

  • In procedural systems, data is stored in objects, while in object-oriented systems, data is stored in databases
  • Procedural systems use top-down programming, while object-oriented systems use bottom-up programming
  • Procedural systems focus on functions and procedures, while object-oriented systems focus on data and objects (correct)
  • In procedural systems, inheritance and polymorphism are widely used, while in object-oriented systems, they are not
