Member functions are written just like any other functions.
One difference, though, is they can use the data member names as is.
Thus, the member functions in
in an unqualified manner.
When invoked on a particular object
, the member functions act on a specified member of that object.
Member functions that are defined within the
are implicitly inline.
As a rule, only short, heavily used member functions should be defined with the
Other member functions should be defined external to the
. We will look at defining external member functions in the next module.
By default, all members of a class declared with the class keyword have private access for all its members.
Therefore, any member that is declared before one other class specifier automatically has private access. For
At the level of programming, a class is a data structure with
- data members for representing the various properties of the different object instances of the class, and
- with member functions for representing the behavior of the class.
