Questions and Answers

What is the key characteristic of an object in O-O programming?

  • It contains both data and behavior (correct)
  • It is a standalone method
  • It contains only data
  • It contains only behavior

What is the outcome of having uncontrolled access to data in procedural programming?

  • Improved code reusability
  • Tighter control over data access
  • Unpredictable access to data (correct)
  • Easier testing and debugging

What is the main difference between procedural and object-oriented programming?

  • Procedural programming uses methods, while O-O programming uses functions
  • Procedural programming separates data and behavior, while O-O programming combines them (correct)
  • Procedural programming uses data structures, while O-O programming uses objects
  • Procedural programming is used for small projects, while O-O programming is used for large projects
