Inheritance means a class is derived from the base class.The derived class contains base class's properties and its own properties.

Polymorphism means one name and many forms.The name is same but it do different things.

Inheritance : A class can be extending existing class & inheriting it's properties(attributes &  behaviours).

Polymorphism: Ability of an object to have more than one forms , which is direct result of inheritance

Polymorphism can be classified into 2 categories:1. Overloading : When 2 or more functions of the same class performing same logical activity have same names but different signatures (type and order of parameters) then calls to such methods are bound at compile time (early binding).2. Overriding: This property is available for inherited classes (A by product of inheritance). When a derived class has same signature (method name and argument order & type) as it's parent class then a method invocation from a base class reference is bound at runtime (late binding) based on the object type the reference points to. That is if the object is of derived class the derived class method is called otherwise the if the object is of parent class the parent class implementation of the method is called
