A virtual function (also known as virtual methods) is a member function that is declared within a base class and is re-defined (overridden) by a derived class.
A virtual function is a member function in the base class that we expect to redefine in derived classes. In this tutorial, we will learn about the C++ virtual function and function overriding with the help of examples.
In C++, a virtual function is a member function that is declared in a base class and redefined in a derived class. It enables runtime polymorphism in our program. In this article, we will learn how to create a virtual function in C++.
A virtual function is a member function of base class which can be redefined by derived class. A pure virtual function is a member function of base class whose only declaration is provided in base class and should be defined in derived class otherwise derived class also becomes abstract.
In object-oriented programming such as is often used in C++ and Object Pascal, a virtual function or virtual method is an inheritable and overridable function or method that is dispatched dynamically.
A virtual function is a special type of member function that, when called, resolves to the most-derived version of the function for the actual type of the object being referenced or pointed to.
The virtual specifier specifies that a non-static member function is virtual and supports dynamic dispatch. It may only appear in the decl-specifier-seq of the initial declaration of a non-static member function (i.e., when it is declared in the class definition).
What is Virtual Function in C++? A virtual function is a form of a member function declared within a base class and redefined by a derived class. The keyword virtual is used to create a virtual function, preceding the function's declaration in the base class.
A virtual function is a member function which is declared within a base class and is overridden by a derived class. Now, when you refer to a derived class object using a pointer to the base class, you can call a virtual function for that object and execute the derived class’s version of that particular function.
The virtual function provides the ability to define a function in a base class and have a function of the same name and type in a derived class called when a user calls the base class function.
