Animal Farm

Animal Farm Project

Animal Farm is a C++ project that demonstrates advanced object-oriented programming concepts through the implementation of a virtual animal management system. The application showcases the use of inheritance, polymorphism, and data structures, particularly focusing on a custom implementation of a singly linked list.

As the sole developer, I was responsible for designing and implementing the entire system. I began by creating a robust class hierarchy for different animal types, starting with a base Animal class and extending it to create more specific classes like Mammal and Cat. I then developed a custom SinglyLinkedList class to efficiently manage and store the animal objects.

Key features of the Animal Farm project include:

1. Extensible animal hierarchy: The project allows for easy addition of new animal types through inheritance.
2. Custom data structure: A singly linked list implementation provides efficient storage and retrieval of animal objects.
3. Weight management: A Weight class handles various weight units and conversions (pounds, kilograms, slugs).
4. Error handling and validation: Extensive error checking ensures data integrity throughout the system.

Here’s a code snippet that illustrates how we add animals to our custom linked list and interact with them:

SinglyLinkedList catDB;
catDB.push_front(new Cat("Loki", Color::CREAM, true, Gender::MALE, 1.0));
catDB.push_front(new Cat("Milo", Color::BLACK, true, Gender::MALE, 1.1));
catDB.push_front(new Cat("Bella", Color::BROWN, true, Gender::FEMALE, 1.2));

for(Animal* pAnimal = (Animal*)catDB.get_first(); pAnimal != nullptr; pAnimal = (Animal*)List::get_next((Node*)pAnimal)) {
    cout << pAnimal->speak() << endl;
}

This project not only demonstrates proficiency in C++ programming but also showcases understanding of important software engineering principles such as code organization, error handling, and creating reusable and extensible code structures.
