Obiect Oriented Concepts
Inheritance . The process of deriving a new class from an existing class is called as Inheritance . The existing class is referred to as the base class or super class and the new class is called the derived class or subclass. Through Inheritance, C++ strongly supports the idea of Reusability. That is making use of the existing features to create the new feature. All the objects in this world come under some kind of classification. Inheritance allows the creation of hierarchical classification. .
Inheritance - Protected Members The 'private' members cannot be accessed outside the scope of the class. The derived class also cannot access the private members. .Sometimes, we want the derived class to access the private members of the base class but at the same time, we don't want other classes or functions to access those members thru the objects. Those members come under protected access specifier .In other words, protected members are private to all, but public to its derived classes.
Inheritance - Constructors & Destructors .Constructors & Destructors are not inherited whatever may be the access specifier used. When you create object of Derived, Base class default constructor is executed first and then derived class constructor is executed . If you want to execute a specific Base class constructor during derived class object creation, you can specify that in derived class constructor header.
of multiple inheritance .In case base class constructor is executed in the order they appear in derived class declaration. In case of multilevel inheritance, constructors are executed in the order of inheritance. . When the object of derived is destroyed, destructor of derived is executed first and then the base class destructor is executed.
Method Overriding Redefining the methods in the derived class which is already defined in the base class is called method overriding. . When this method is invoked by derived class object, the method defined in the derived class gets executed.
