Abstract
The purpose of this document is to address all items required for the Part 3 of the Programming Development assignment.

Programming Development: Part 3
In the previous weeks, the choice for developing software was for an Animal Shelter and it was also analyzed selection structures. In this paper are analyzed array and loop structures that will be present in the program as part of its implementation.

Identified Objects

For the Animal Shelter system there are many things that could become an object if this program is developed using an Object-oriented Programming Language. Among the most important we have User, which would identify a user inside the system with its role and some other attributes. Person, which would have all information related to a person and would be related to User. In the system a User is own by a Person. Then we would have Animal and Vaccine too, with all related information applicable. We could have other objects such as Adoption Form, Cage (the cage where the animal stays in) and Treatment but in any case, the object-oriented approach will help achieve the desired levels of encapsulation and data hiding. “The term encapsulation means to package data members and methods into a single programming unit (in our case, a class or an object created of that class) with a well-defined external boundary, or interface. Encapsulation is most often achieved through data hiding, which is the process of hiding all the facts, or secrets, of a class that do not contribute directly to others’ ability to use it” (Bohl & Rynn, 2008).

Array structure selection

The array structure selected is for one of the steps of creating or adding a new animal into the system, in the past week’s assignment we stated that at this step the user will be prompt to input all
