CLASSES AND OBJECTS IN DETAIL 

So far, you have got very basic idea about C++ Classes and Objects. 
There are further interesting concepts related to C++ Classes and Objects 
which we will discuss in various sub-sections listed below: 




Concept            Description 
Class member functions    A member function of a class is a function 
                          that has its definition or its prototype within 
                          the class definition like any other variable. 
Class access modifiers    A class member can be defined as public, private 
                          or protected. By default members would be assumed as private. 
Constructor & destructor  A class constructor is a special function in a class 
                          that is called when a new object of the class is created. 
                          A destructor is also a special function which is called 
                          when created object is deleted. 

C++ copy constructor   The copy constructor is a constructor which creates 
                         an object by initializing it with an object of the same class, 
                         which has been created previously. 
C++ friend functions   A friend function is permitted full access to 
                         private and protected members of a class. 
C++ inline functions   With an inline function, the compiler tries to 
                         expand the code in the body of the function in 
                         place of a call to the function. 
The this pointer in C++  Every object has a special pointer this 
                         which points to the object itself. 
Pointer to C++ classes   A pointer to a class is done exactly the same way 
                         a pointer to a structure is. In fact a class is 
                         really just a structure with functions in it. 
Static members of a class  Both data members and function members of a class can be declared as static.
