  class that is inherited is class the base class and a class that is inheriting the
  members of another class is called the derivied class
  BASE CLASS access controll
  class derived_class_name : access base_class name
  {
   code 
   } 
  the base class access specifier must be either public private or protroted if no 
  access specifier is present the defualt will be private for the class
