A virtual function<\/a> (VF) is a member function defined in a base class that is redefined (overridden) by a derived class. When you refer to a derived class object using a pointer or a reference to the base class, you can call a virtual function for that object and have it execute the derived class’s version of the function.<\/p>\n\n\n\n

A virtual function in C++ is a base class member function that can modify in a derived class to enable polymorphism. To declare the function in the base class, use the virtual keyword. You can use a pointer or reference to call the virtual class and run its virtual version in the derived class after declaring the function in the base class. As a result, it asks the compiler to detect the object’s type and build a function bind at runtime (late binding or dynamic linkage).<\/p>\n\n\n\n
