Data abstraction is a process of representing essential
features without showing the background details.
For example:
#include<iostream.h>
#include<conio.h>
#include<math.h>
void main()
{
clrscr();
int a,b;
cout<<"enter a";
cin>>a;
b=sqrt(a);
cout<<"square of a="<<b;
getch();
}

In the above example,we are doing the square of "a" where
we can only see/use the sqrt function but we cant see the
background deails like coding of sqrt().
