* these are the special member fun" used for automatic
initialization of the object of the class.
* these r defined along with other member fun"of the
class,but the format of the constructor definition is diff.
from the other member fun".
* constructor can take parameters in their parameter list as
needed, called parametrized constructor.
* but they can't return a value,not even void.
* the name of the constructor is same as that of the class.
* constructor r called automatically whenever an object of
the class is created.
* a constructor without any parameter is called default
constructor.
* there is one another type,called copy constructor.compiler
will use the copy constructor whenever you initialize an
instance using values of another instance of same type.
