Exercise: Access Methods for Members
====================================

.. contents::
   :local:

Description
-----------

In exercise :doc:`../user-simple-method/exercise`, you had to modify
``class User``: you removed the ``const`` specifier from the ``age``
member. ``age`` is still ``public``, which gives everybody permission
to write to ``age`` - not only class methods.

Introduce a ``private`` section, and put *all* (not just ``age``) into
that section. This will break all code that accesses members
directly. 

**Fix that**: introduce *access methods* for the members.
