Abstraction refers to the act of representing essential
features without including the background details or
explanations.

Encapsulation is the procedure of covering up of data and
functions into a single unit (called class).

FOR EXAMPLES AND MORE INFO GOTO :

public class School
{
private string Schooldepartname;
public string SchoolDepartname
{
get
{
return Schooldepartname;
}
set
{
Schooldepartname =value;
}
}
}
public class Departmentmain
{
public static int Main(string[] args)
{
School d= new School();
d.SchoolDepartname="Communication";
Console.WriteLine("The Dept. Name is :
{0}",d.SchoolDepartname);
return 0;
}
}

From the above we can see the use of Encapsulation by using
properties. The property has two accessor get and set. The
get accessor returns the value of the some property field.
The set accessor sets the value of the some property field
with the contents of "value". Properties can be made read-
only. This is accomplished by having only a get accessor in
the property implementation.

Abstraction
Any function having lines of code we dont need the code of
function ie hiding detail but we know that what result we
are getting ie (showing essential )

Question In a class, there is a reference or pointer of an object of another class embedded, and the memory is either allocated or assigned to the new object created for this class. In the constructor, parameters are passed to initialize the data members and the embedded object reference to get inialized. What measures or design change should be advised for proper destruction and avioding memory leaks, getting pointers dangling for the embedded object memory allocation? Please suggest.

Answer # 1 use copy constructors 0 Shanthila There is something to be taken care in destructor, in copy constructor, suppose the memory is assigned to the embedded member object pointer with the parameter passed value, but if some other objects of different class also are pointing to this memory, then if some one deletes the object then this class member pointer object will become dangling, or if the object is not deleted properly then there will be memory leak. Please suggest the design change required to handle or avoid this situation
