Questions and Answers

What is inheritance in object-oriented programming?

  • The act of reusing code without basing it on existing classes
  • The process of creating new classes from scratch
  • The mechanism of basing an object or class upon another object or class, retaining similar implementation (correct)
  • The method of combining multiple classes into one

What does a 'child object' acquire from a 'parent object' in inheritance?

  • All the properties and behaviors, including constructors, destructors, overloaded operators, and friend functions
  • All the properties and behaviors, except for constructors, destructors, overloaded operators, and friend functions (correct)
  • Only the properties and constructors
  • None of the properties and behaviors

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

  • To restrict the behaviors of classes
  • To eliminate the need for creating new classes
  • To limit the reuse of code
  • To create classes built upon existing classes, reuse code, and specify new implementations while maintaining the same behaviors (correct)
