Can Base And Derived Class Have Same Function?

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..

Can base class access members of derived class give reasons?

No, you cannot access derived_int because derived_int is part of Derived , while basepointer is a pointer to Base . Derived classes inherit the members of the base class, not the other way around. You’re dancing on a minefield here. The base class can never know that it’s actually an instance of the derived.

Which concept implements late binding?

Which concept is used to implement late binding? Explanation: Virtual functions are used to implement the concept of late binding i.e. binding actual functions to their calls.

Why is late binding important in oops?

The primary advantage of using late binding in Component Object Model (COM) programming is that it does not require the compiler to reference the libraries that contain the object at compile time.

What members can a friend class access from another class?

Friend Class A friend class can access private and protected members of other class in which it is declared as friend. It is sometimes useful to allow a particular class to access private members of other class. For example a LinkedList class may be allowed to access private members of Node.

What is base class example?

A class derived from a base class inherits both data and behavior. For example, “vehicle” can be a base class from which “car” and “bus” are derived. Cars and buses are both vehicles, but each represents its own specialization of the vehicle base class.

What does a derived class automatically inherit from the base class?

What does a derived class automatically inherit from the base class? All of these. When you define a derived class, you give only the added instance variables and the added methods as well as all the methods from the base class. You may substitute the keyword this for super() to call a constructor of the derived class.

What happens if the base and derived class contains definition of a function with same prototype?

What happens if the base and derived class contains definition of a function with same prototype? Compiler reports an error on compilation. Only base class function will get called irrespective of object. Only derived class function will get called irrespective of object.

How do you call a derived function from base class?

You could do something like this: class Base { public: Base() {} virtual ~Base() {} virtual void start() { startInternal(); } virtual void stop() { stopInternal(); } void doSomething() { startInternal(); // … stopInternal(); } private: void startInternal() { // … }

How will a class protect the code inside it?

How will a class protect the code inside it? Explanation: Each method or variable in a class may be marked ‘public’ or ‘private’. They are called Access Specifiers.

Why late binding is late and dynamic?

Late binding: In the late binding or dynamic binding, the compiler doesn’t decide the method to be called. Overriding is a perfect example of dynamic binding. In overriding both parent and child classes have the same method.

What does derived class inherit 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.
