A class is a user defined data type consisting of data and member functions. It is the basis of encapsulation in C++.

Object is an instance of a class.

A class is a user defined data type. It is a logical construct.
An Object is an instance of a class. It is the physical reality.

A class is the basis of abstraction. Encapsulation is a design characteristic of OO.

class is make object
but object is genrate any event.

Class is rather static with compared to object.

Class attributes does not change whereas attributes of objects change significantly over the life time of object.

Objects can be created and destroyed, Classes are not.

This difference can be viewed in line with the a program and a process.

A class is a piece of instructions, which are effectively passive.
An object is an active entity, that represents an instance of the class(data type).

Here is a simple and practical answer:

Class is the Die i.e. it is like a pattern to make a widget
Objects are the widgets made out of the class - i.e. they are the real intances of the class - i.e. Use the die to make as many widgets as you want - it is mass production!

In terms of CS, a class is a souped-up C structure. An object is a running instance of that representation in memory.

A class is a blueprint of an object. A class defines a collection of datatypes, storage types of the defined datatypes and the functions/operations that can be performed on the datatypes as well on the whole class itself. A object is an instantiation/creation of the datatypes defined in the class complying to the rules specified in the class definition. For Ex: instantiation of static & instance variables etc.
