In compile Time polymorphism (i.e overloading) compiler doesn't need to check reference of an object/reference variable but in case of run-time polymorphism, it is required to check reference of Object.

Polymorphism means one name and multiple implementations.
We have two types of polymorphism early binding and late binding in early binding we are able to know at compile time but in late binding we will know at run time what actually the function will be called.

- Runtime polymorphism allows a base class reference or pointer to refer to a derived class object.
- But compile-time polymorphism, the compiler only sees the reference type unless the function is marked virtual.

If object is created run time by using base class pointer (allow to store address of any derived class)/reference and base class functions are virtual and overridden in derived class then base class pointer calls the function of derived class.
