Class Objects:


Class Objects:
   An Object is an instance of a class. Creating an object of a class is like defining a variable of a data type. Once a class has been declared, we can create variables of that type by using the class name. Syntax for creating an object is
  class_name object_name;
e.g.
   box b1; // here box is assumed to be a class name
The statement box b1; creates a variable b1 of type box. This variable b1 is known as object of the class box. Thus, class variables are known as objects. The objects can also be created when a class is defined by placing their names immediately after the closing braces like
      class box
                   { private:
                            ……..
                       public:
                          ……
                    }b1,b2,b3; 
 But, this technique is rarely used in practice.
