Array Definition

Array — is just a data structure with the number of values making up its elements indexed either by an index or a set of indices which takes the values from some specified range of values that the index can take.

Dimensionality is the number of indices to be defined in terms of array when addressing without causing ambiguity to any member of the array. The classification of the arrays assumes a form and amounts to the number of indices used: 1d, 2d, 3d.

So, the case is simple: an array is a constant-length array for all the dimensions, and if it is only data of one type present in the array, as is described. Similarly, dynamic arrays have many other languages on which its length can be changed at runtime of program as well as have the support of heterogeneous arrays in which in different data can be stored in different elements.

The advantage of using the array is the convenience in addressing the element by index and at the same time of access to all the elements; this is so because all the elements of the array are positioned one by one.
