Why Use Arrays?

Arrays allow us to manipulate groups of data at the same time. They also provide us with a compact represenation of doing so.

Without arrays, some programs would need millions of predefined variables. As you can guess, arrays can get as large as memory will allow.

Due to the way arrays are structured, they work well with many forms of programming, including the ever popular incremental loop.


	Real Life Example

	We use the filing cabinet to keep ourselves organized. We may also easily access related data.
