Arrays Data Structure

Arrays are fundamental data structures in programming that allow you to store multiple values of the same data type under a single variable name. They provide a convenient way to access and manipulate collections of elements.

Each element in an array is identified by its index, which is a non-negative integer. Array indexing typically starts at 0, meaning the first element of the array is at index 0, the second element is at index 1, and so on.

For example:
int[] arrayOfIntegers = new int[5];

This line of code initializes an array arrayOfIntegers capable of holding 5 integers. In memory, this would look like a block of memory with space allocated for 5 integers, but they're not assigned any specific values until you do so explicitly.
