Exercise: Access Methods for Members¶
Description¶
In exercise Exercise: Simple Method (Users Age By n Years), 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.
