Functions which are called at runtime are known as virtual functions. Virtual functions are used to encorporate runtime polymorphism or in other words dynamic binding.

Virtual Functions are useful in implementing polymorphism which is runtime binding/dynamic binding;

Whereas Overloading(Function Overloading & Operator Overloading) implement compile-time binding/static binding;

Virtual functions are used in case of inherited classes(base class & derived class); By using virtual function it is possible to use the base class pointer to point to the derived class object;
