Question

NOTE - Submission in parts. Parts required - Dog Class Code, Dog Manager Class Code and the main code. Please differentiate all three in the answer.

This Assignment is designed to take you through the process of creating basic classes, aggregation and manipulating arrays of objects.

Scenario:

A dog shelter would like a simple system to keep track of all the dogs that pass through the facility.

The system must record for each dog:

dogId (int) - must be unique

name (string)

age (double) - cannot be less than 0 or more than 25

breed (string)

sex (char) – m for male, f for female

foundHome (bool)    - true means the dogs has been places in a home false otherwise.

You must create an object oriented solution with a text based menu as summarized on the next page. The system must check that valid data is entered. For example, the menu has four items so only 1 to 5 must be allowed as input from the menu.

Summary of Operations

System Menu:

1. Add dog
2. View all dogs
3. View all available dogs
4. View dog
5. Update dog home status
6. exit

Overview:

Add Dog:

When a dog is added to the system, you must check that the dogId is not already used in the system. All new dogs have no home as yet (foundHome = false).

View all Dogs:

This menu option shows all dogs in the system. This includes dogs that have a home and those that do not.

View all available dogs:

Shows all dogs in the system, that have no homes as yet.

View dog:

Asks the user for a dogId and then displays the dog information if found and “There is no dog with that id..” if it is not found.

Update dog home status:

Asks the user for a dogId. If a dog with that id is found, the “foundHome” status is changed to true and the dog information is to be displayed. If the dog is not found the message “There is no dog with that id..” should be displayed.
