Dear Mann_19,

Virtual functions are functions declared with a virtual keyword in the base class. Concrete derived classes override virtual functions from the base class by implementing the virtual function in the derived case. The resolution of a specific function call is done at run-time.

In Late Binding function call is resolved at runtime. Hence, now compiler determines the type of object at runtime, and then binds the function call. Late Binding is also called Dynamic Binding or Runtime Binding.</li></ul>

The keyword virtual in C++ tells the compiler to support runtime polymorphism.
When used with a function (like virtual void operation()), it means that the function can be overridden in derived classes, and the correct version will be called based on the actual object type at runtime — even if accessed through a base class pointer or reference.
