abstract class is a class which may or may not contain
abstract method.
abstract class can,t be instantiated i.e. we can,t
create object of an abstract class.
abstract class can be subclasses .
abstract class is a class which is declared abstract.
if any class contain abstract method then it can be
declared abstract.

abstract public void display();//abstract method
}
abstract method is method which is declared but not
implemented i.e. without braces followed by semicolon.

A class with atleast one pure virtual function is called
abstract class.It cant be instatiated.It can be used as a
base class for other classes. The class derived from an
abstract base class can be instantiated,provided it should
implement the abstract base class pure virtual function.

This program numbers the lines found in a text file. Write a program that reads text from a file and outputs each line preceded by a line number. Print the line number right-adjusted in a field of 3 spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (i.e., wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before processing the lines of the file. This version of the program should insert a new line after the last complete word that will fit within a 72-character line.
