2. Example 2: using a class pattern

In the previous example, we deliberately avoided using standard components.

However, if we're only interested in the class's functionalities, apart from output on a stream, these are provided in full by the standard set component (its use requires the inclusion of the set header file). There are several approaches to output on a stream. You can, of course, program it as and when required, each time writing a few instructions for traversing the :

Example

set ens ;

set::iterator ie ;

.....

for (ie=ens.begin(); ie!=ens.end(); ie++) cout << *ie << " " ;
