In inheritance, a class (derived class) inherits the features i.e. methods and properties from the parent class (base class). Polymorphism occurs when multiple classes are inherited from each other. Here call to a member function (of the class) causes a different function to be executed (from the classes linked via inheritance) depending on the type of object that invokes the function.
