Difference between object and class:

The following table shows the difference between “object” and “class”.

ObjectClass
An object is an instance of a class.A class is a category of objects.
An object represents an entity in the real world that can be distinctly identified.A class uses variables to define data fields, and functions to define behaviors of the class.

Object is followed by the class name.

Class name is represented with the keyword “class”.

Syntax for creating an object:

Classname objectname;

Sample code:

Circle r1;

Syntax for defining a class:

class classname

{

// Body of the class

};

Sample code:

//Declare the class

class circle

{

Private:

double radius;

};
