When The Base Class Is Publicly Inherited Public Members Of The Base Class Become?

Public Inheritance − When deriving a class from a public base class, public members of the base class become

public members of the derived class

and protected members of the base class become protected members of the derived class.

When a base class is inherited publicly?

6. Which of the following statements is correct when a class is inherited publicly?

Public members of the base class become protected members of derived class

. Public members of the base class become private members of derived class.

What happens when a derived class inherits a base class privately?

Answer: With private inheritance,

public and protected member of the base class become private members of the derived class

. That means the methods of the base class do not become the public interface of the derived object. However, they can be used inside the member functions of the derived class.

When the inheritance is public the private methods in base class are?

When the inheritance is private, the private methods in base class

are inaccessible in the derived class

(in C++).

What are the things that inherited from the base class?

Which access specifier is most secure during inheritance?

Explanation:

The private members

are most secure in inheritance. The default members can still be in inherited in special cases, but the private members can’t be accessed in any case.

What does derived class does not inherit from the base class?

When you define a class to derive from another class, the derived class implicitly gains all the members of the base class, except for its

constructors and finalizers

. … These members include a constructor, because constructors aren’t inherited.

Which members can be accessed in derived class from the base class?

A derived class can access

all the non-private members of its base class

. Thus base-class members that should not be accessible to the member functions of derived classes should be declared private in the base class. Constructors, destructors and copy constructors of the base class.

Which members can never be accessed in derived class from the base class?

Which members can never be accessed in derived class from the base class? Explanation: There is no restriction for a derived class to access the members of the base class until and unless

the members are private

. Private member are declared so that those members are not accessible outside the class.

What is the syntax of inheritance of class?

Which is the correct syntax of inheritance? Explanation: Firstly,

keyword class should come, followed by the derived class name. Colon is must followed by access in which base class has to be derived, followed by the base class name

. And finally the body of class.

Can we inherit private class?

Private Members in a Superclass

A

subclass does not inherit the private members of its parent class

. However, if the superclass has public or protected methods for accessing its private fields, these can also be used by the subclass.

What is the difference between public and private inheritance?

public inheritance makes public members of the base class public in the derived class, and the protected members of the base class remain protected in the derived class. …

private inheritance makes the public and protected members of the base class private in the derived class

.

Can private data members be inherited?

The private members of

a class can be inherited

but cannot be accessed directly by its derived classes. They can be accessed using public or protected methods of the base class. The inheritance mode specifies how the protected and public data members are accessible by the derived classes.

Is used to design the base class?

Which class is used to design the base class? Explanation:

Abstract class

is used to design base class because functions of abstract class can be overridden in derived class hence derived class from same base class can have common method with different implementation, hence forcing encapsulation.

Which value is placed in the base class?

2. Which value is placed in the base class? Explanation: We

can place the default type values in

a base class and overriding some of them through derivation.

Which advantages we lose by using multiple inheritance?

3. Which of the following advantages we lose by using multiple inheritances? Explanation: The benefit of

dynamic binding and polymorphism

is that they help making the code easier to extend but by multiple inheritance it makes harder to track.
