A Class is actually a blueprint or a representation of how an Object has to be instanciated. Whereas an Object is called as the Instance of a Class.

For Eg:
  Class can be assumed as a blueprint of a car, describing how it has to look, how it has to work, so on..
  Whereas the Object is the real car.

Adding to the above answer,

The instance is the actual object created at runtime

Class describes the general behaviour of objects where as instance is the condition of class at a particular time (run time).

A Class is a generalization about things (objects) describing their properties, functions, etc.

An object is an instance of a Class in an specific point of time with different values, that represent the STATE of the object.

The Class is a blueprint which holds the code, but the instance is the real object inside the memory so we can access its properties and methods in the Run-time.

Class contains the declaration and definition of all of it member variables and the member functions, along with their respective access specifiers. A Class remains same for all of it's objects or instances.

Object is a mere instantiation of a class. All the member variables and the member functions of a class are used via the object, except the static ones. For every instance/object created of a class a different set of member variables and function references is created. Thus each object has it's own set of member variables. when a function of a class is called on an object, of that class, what all changes/operations/updations are done are specific to that object. Static member variables and static functions are exceptions to this.
