Answer / sureshkumar koppineedi
C is a procedural oriented language .
c++ is a object oriented language.
OOps concepts are 1)encapsulation:-Taking data and methods
as an unit is called encapsulation.
2)Abstraction:-Hiding unnecessary data from the user is called
abstraction
3)Inheritence:-producing new classes from the existing classes.
4)Polymorphism:-Ability to exist in more than one form.

Answer / shailesh bahuguna(kec)
basically c does not support the object oriented features
that means we cannot relate the real world entities together
which can be expressed through C++ which is the extention of
c with OOPs concepts

C++ can be viewed as the revolution in the field of object
oriented programming paridigm.

small problems and then make it to be a solution.

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
