		arrays are structured as follows

		return_type arrayName[arraySize];
		
		return_type - the type of data we're storing, like  int, char, double, etc
		arrayName   - the name we're giving the array
		arraySize   - inside the brackets, we tell the array how many elements we're going to store.
					  inside the array
		other key things to remember:

		 index  - the location within the array 
		 		  the first index you can store things in would be at index 0
		 		  the last index you can put things in would be at index SIZE - 1
		 		  where SIZE is the number of elements the array can store

		element - whatever value is inside the array at the given index
