Introduction To


An array is collection of items stored at contiguous memory locations. The idea is to store multiple items of same type together. This makes it easier to calculate the position of each element by simply adding an offset to a base value, i.e., the memory location of the first element of the array (generally denoted by the name of the array).

After the array is created, the values can be assigned. There are different ways to declare, create, and assign arrays.

Array elements are numbered starting with zero, which may seem confusing at first but is an important detail for many programming languages. The first element is at position [0], the second is at [1], and so on. The position of each element is determined by its offset from the start of the array.
