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.
