What is Class and Object in Oops || definition of Classes & Objects

We can make a program in Procedure oriented like C . But when C++ comes and says about Object Oriented Programming Language( Oops ) , then Class & Object comes into picture .

If we want to make a program in object oriented,then we must have to know about Class & Object which is main attributes of Oops . If you don't know much about it, don't worry . Take a seat , and let's start .

 Class is a blueprint of Object where Object is a real world entity . Now whoever reading this blog , consider that I am a Object , that's great .. Now let's see with an example below then will discuss rest

 

..

      So if I consider Human as a Class & myself as an Object , then its definite I must be some properties and behavior .. So here we can say skin color , age , eye color , height etc as properties of myself . I am 22 year's old so 22 year's is an property and I can talk so here talk() is an function ( behavior ) of myself . So there are some common attributes or characteristics which can define me or which can define a Object is called Class .
  So we can say that Class is a blueprint of an Object which stores properties and functionalities of an Object mean what can Object do actually and what things present in an Object whereas these properties and functionalities are implemented by something which is nothing but Object .
 
So a Class can have many Objects . We can say that Class is a data-type and Object is Class type Variable ,let's see with an example below :

         So in the above example a Class Person has defined,and then P1 means object of that class has been created . And I have shown you also int type variable c,and I have compared it with object P1 , cause Person class also defining the type of P1(object) , which works as same as integer .
 
   We can say finally , an object is nothing but an instance of a class. A class can be defined as a template or we can say as a blueprint that defines the behavior or state that the object holds .
Keep Practice it .
