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.
