1. ConceptInheritance: When defining a new class B, if the class is similar to a known class A (meaning that B has all the features of a), then you can use a as a base class and B as a derived class (also called a subclass).
Derived classes are obtained by modifying and augmenting the base class. In a derived class, you can extend new member variables and member functions.
Once a derived class is defined, it can be used independently and not dependent on the base class.
Derived
