Arrays

An array is one of the fundamental data structures available and most widely used by developers today to solve general problems. You can think of an array as a collection of variables of a certain data type stored contiguously in memory. The values of an array can be accessed through an index (commonly represented by the variables i, j, and k), and the ith value of an array is denoted as Array[i].

This article is not to be confused with associative arrays, which is a fancy way of calling the key-value-pair data structure. We will discuss it separately.
