+ Array is to store multiple items of the same data-type,such as an integer or string under a single variable name.
+
+ Arrays are used to organize data in programming so that a related set of values can be easily sorted or searched.
+
+ - They're stored in contiguous memory locations.
+ - They can be accessed programmatically through their indexes (array[1], array[0], etc.)
+ - They're mutable.
+ - Their size is fixed.
