Quick Answer: When more than one class is derived from a base class, the situation is called?

What is it called when a derived class inherits features from more than one base class?

Explanation: When more than one classes are being derived from a single parent class, the inheritance is known as hierarchical inheritance.

When a base class is privately inherited by the derived class then?

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.

When a sub class inherits only from one base class it is known as?

Single Inheritance): When a sub class inherits only from one baseclass, it is known as single inheritance. Multiple Inheritance: When a sub class inherits from multiple base classes, it is known as multiple inheritance.

How do you call a base class function from a derived class?

Call the parent method with the parent scope resolution operator. If access modifier of base class member function is protected OR public, you can do call member function of base class from derived class. Call to the base class non-virtual and virtual member function from derived member function can be made.

How many classes can be derived from the base class using hierarchical inheritance?

4. How many classes must be there to implement hierarchical inheritance? Explanation: At least 3 classes must be there. Two derived classes and one base class.

Can a final class be a base class?

Why a final class cannot be inherited but a final method can be inherited? A final class cannot be extended. A final method cannot be overridden. A final variable cannot be assigned to after it has been initialized.

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

Not all members of a base class are inherited by derived classes. The following members are not inherited: Static constructors, which initialize the static data of a class. Instance constructors, which you call to create a new instance of the class.

How the relationship is made in association?

How the relationship is made in Association? Explanation: Association relationship between classes is made using the objects of classes like we have a bank object denoting ABC bank and some objects of Employee class XYZ1, XYZ2 and so on.

Which of the following can derived class inherit?

Which of the following can derived class inherit? Explanation: Both data members and member functions are inherited by derived class in C++.

How many derived class can a single base class have?

6. How many derived class can a single base class have? Explanation: There is no restriction on how many classes can inherit a single base class. Hence there can be as many derived classes as required in a program from a single base class.

What is base class and derived class?

Base Class: A base class is a class in Object-Oriented Programming language, from which other classes are derived. A base class is also called parent class or superclass. Derived Class: A class that is created from an existing class. The derived class inherits all members and member functions of a base class.

What is not type of inheritance?

Explanation: All classes in java are inherited from Object class. Interfaces are not inherited from Object Class. Static members are not inherited to subclass.

How do you call a base class function?

To have a derived function call a base function of the same name, simply do a normal function call, but prefix the function with the scope qualifier (the name of the base class and two colons). The following example redefines Derived::identify() so it first calls Base::identify() and then does its own additional stuff.

Can base and derived class have same function?

Suppose, the same function is defined in both the derived class and the based class. Now if we call this function using the object of the derived class, the function of the derived class is executed. This is known as function overriding in C++. The function in derived class overrides the function in base class.

Can a derived class pointer point to a base class object?

Because a base class pointer can point to an instance of the base class or any derived type. A derived pointer cannot be assigned a pointer to a base type without casting simply because it cannot tell if the base pointer is of the Derived type or one of its children.
