Question 1

What Is Inheritance?

Answer 1

Provides a way to create a new specialized version class from an existing class

Question 2

• Inheritance establishes an …………relationship between classes.
• ………. (or parent ) – inherited from
• ………..(or child ) – inherits from the base class
• An object of a …………….’is a(n)’ object of the ……………..
• A ………… has all of the characteristics ,of the
  base class
• An object of the derived class HAS all …………..and …………..in the parent class
• An object of the derived class CAN USE …………… and ……………….in the parent class

Answer 2

• “is a”
• Base class
• Derived class
• derived class ,base class
• derived object
• defined and declared members
• PUBLIC defined and declared members

Question 3

1) …………..– object of derived class can be treated
as object of base class
2) …………..- object of parent class canNOT be treated as oject of derived class
3) ……………. – more restrictive than public,
but allows derived classes to know details of
parents
4) …………. – prevents objects of derived class
from being treated as objects of base class.

Answer 3

• public
• public
• protected
• private

Question 4

• ……………members are accessible only within the class in which they are defined.
• ………… are accessible within the class and its derived classes
• …………………..determines how private, protected,
  and public members of base class are inherited by the derived class

Answer 4

private
Protected members
Class access specification:

Question 5

• overloading is allowed in (destructors / constructors)
• only oe of it is allowed per a class (destructors / constructors)
• Name is tilde (~) followed by the class name (destructors / constructors)
• Receives no parameters, returns no value (destructors / constructors)
• can Receive initialization parameters, but returns no value (destructors / constructors)

Answer 5

• constructors
• destructors
• destructors
• destructors
• constructors

Question 6

• Derived classes can have their own constructors and destructors
• When an object of a derived class is created, the ………….class’s constructor
  is executed first, followed by the……… class’s constructor
• When an object of a derived class is destroyed, ………….. class’s destructor is executed first, followed by the……… class’s destructor

Answer 6

base ,derived
derived , base

Question 7

what isa static binding?

Answer 7

also known as early binding or compile-time binding, function to be called is determined based on the type of the variable, rather than the type of the object it points to.
