An array is a special type of variable. It doesn’t just store one value, it stores a list of values.
You should consider using an array whenever you are working with a list or a set of values that are related to each other.
It is useful when you want to create a list of n values. Which array is not limited to a number of values in your list.

Values in an array are accessed as if they are in a numbered list. It is important to know that the numbering of this list starts at zero (not one).
