difference between abstraction and encapsulation with progarammatic eg.
hi,just recently i went for an interview .The interviewer asked what is the difference between abstraction and encapsulation with programmatic eg.
I gave the answer as
encapsulation mean hiding the relevant data which is not useful for the user, eg a electric fan .hiding the information how the electricity is converted into machanical energy.
abtraction showing only the relevant data to the user eg electric fan.
it look ,its color ,it design etc only relevant data.
Then the interviewer asked me, give me some programmic eg .I Said
Let assume a web form having control like textbox,button etc.
The user can view textbox,button etc this is the eg of abstraction
and when the user click on the button how he is redirected is not known by the user is the eg of the encapsulation.
Am I Correct .was the answer given by me is perfect .now i am planing to go for an another interview should i give the same answer.IF not please suggest me a better answer.with some good eg Please help

What is the purpose of enum?
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.
