The Purple Martin

In this quest you get to create a Pet Store using the Pets

you created in the last quest.

The name of the class you will implement is Pet$\_$Store.

In addition to implementing this class, you will have some

fun creating some efficient $($and not$-$so$-$efficient$)$ search

functions.

And along the way you'll pick up a new concept:

Enumerated types $($enums$).$ Now is the time to read up

about enums in your reference material of choice, before

you start your quest.

Your first miniquest $-$ Make a Store

You must implement the class Pet$\_$Store containing an inner enumerated type called

$\_$SORT$\_$ORDER which can have three possible values:

$$ BY$\_$ID

$$ BY$\_$NAME

$$ NONE

Define it as follows:

enum $\_$SORT$\_$ORDER $\{$

BY$\_$ID$,$

BY$\_$NAME,
