Inheritance is a feature of objectoriented programming languages that allows you to define a base class that provides specific functionality data and behavior and to define derived classes that either inherit or override that functionality. A derived class includes all features of the generic base class and then adds qualities specific to the derived class. Once a class has been written and tested, it can be adapted by another programmer to suit their requirements. For creating a subclass which is inherited from the base class we have to follow the below syntax. There are many tricky ways for implementing polymorphism in c. Inheritance uses an existing class and adds functionality to it to accomplish another, possibly more complex job.
Inheritance allows us to define a class in terms of. If, however, you believe that a shape is too nebulous to be defined or instantiated, then you need to make at least one of its functions a pure virtual function. It also provides possibility to extend existing classes by creating derived classes. When creating a class, instead of writing completely new data members and member functions. Then the outer world handles your objects by keeping pointers to them, and you provide functions accepting such pointers as the methods of your objects. Inheritance, together with encapsulation and polymorphism, is one of the three primary characteristics of objectoriented programming. Encapsulation can be done by keeping the definitions of your structures in the. Inheritance enables you to create new classes that reuse, extend, and modify the behavior that is defined in other classes.
