Can you please help me answer these questions

What does object oriented programming (OOP) language mean, as opposed to any other language? Why use it over another language? What are the benefits of using classes, objects, methods, properties, etc???

What is the difference between using procedures and functions in your programming? Cite an example of when you would use a procedure, and not a function. Then give an example where you would use a function, and not a procedure. Tell WHY. You do not need to provide hard code, but you do need to provide pseudo code to make your point.

What are arrays? What is their purpose (why use them)? How do you get to a piece of data in the middle of an array? What do you use? (it has a name) Examples always help! Can be pseudo code to make your point.

If you don't have an array, what code would you program to store and access the data?
