Answer / suvarna handore.
Class is a basic entity which allow to combine data and
manipulators. In class definition we need to club data
members and member functions.The usability of structure and
function together in C++ is known as class.
Objects are the basic runtime entities. Object is an
instance of class.To access data members and member
functions within classes, objects are required. We can
access data from outside the class using objects.

Answer / johncz
Class is a template for the custom type that can be used as
variable. It defines types of data that class contains and
the set of functions to manipulate those data types. It is
just a recipe to be used when class is instantiated.
Object is an entity created using class template. Such an
object occupies computer’s memory. Each object of the class
is independent entity.

Answer / kanchi
class is the advance version of structure because it contains the data and functions both so it is wrapped into a single unit called encapsulation.
Object is the instance of class and it always created at run time

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
