-OOP is using objects to represent data and implement functions to encapsulate and modularize the code.

Q2
What are structures and why are they useful?
-structures allow the code to be group accordingly

Q1: What is an instance variable?
- instance variable is a variable that is owned by an instantiated object.

Q2: The 4 Pillars of Object Oriented Programming are Abstraction, Encapsulation, Inheritance and Polymorphism. Describe each one.
Abstraction - to "hide" the logic and control what can be accessed or called by other objects
Encapsulation - to combine related objects, data and operations into a single unit
Inheritance - enable objects to receive/inherit the properties/attributes and methods without requiring it to re-declare or re-implement it
Polymorphism - allows the properties and methods of subclasses to have a different behavoir.

Q1 Explain the different components of MVC - what are their responsibilities?
- Model - data source/holder
- View - all the UI elements
- Controller - displays the view and handles all the interaction between the model and view

Q2 What are some benefits of having an NSObject protocol separate from the NSObject class?
- When delegates conform to the NSObject protocol, the delegates will inherit the retain and release methods. Also, all the objects that will conform to the protocol are required to conform to NSObject protocol

Q1 We are writing an application that makes use of a custom view. This is the header file of our custom view class:
@interface LLView : UIView
@property (nonatomic, weak) UIViewController* parentViewController;

-(instancetype)initWithFrame:(CGRect)frame parent:(UIViewController*)parentVC;
-(void)configureViewWithObject:(LLObject*)object;
@end
Our view also detects taps. When it is tapped, it runs the following code:
LLViewController* nextViewController = [[LLViewController alloc] init];
[self.parentViewController presentViewController:nextViewController];
