Answer 2

Arrays works as collections of items, for instance strings. You can use them to gather items in a single group, and perform various operations on them, e.g. sorting. Besides that, several methods within the framework work on arrays, to make it possible to accept a range of items instead of just one. This fact alone makes it important to know a bit about arrays.

Arrays are declared much like variables, with a set of [] brackets after the datatype.

Write a program of sorting an array. Declare single dimensional array and accept 5 integer values from the user. Then sort the input in ascending order and display output.
