what is object in class c++

Comment

class:
      class is user-defined data type that we use in our programs.
object: 
       object is instance/element of class which inherits all the variables and functions
       from class.
       To access data members and member functions defined in the class, we need to create objects. like obj.brand etc.
Exapmle:
        a car is a class then brand, model etc are its attributes (data members and member functions).
          
When a class is defined, no memory is allocated but when it is instantiated (i.e. an object is created) memory is allocated.
