Sorting is any process of arranging items in some sequence and/or in different sets, and accordingly, it has two common, yet distinct meanings:
Ordering : arranging items of the same kind, class, nature, etc. in some ordered sequence,
Categorizing : grouping and labeling items with similar properties together (by sorts).

In computer science, sorting is one of the most extensively researched subjects because of the need to speed up the operation on thousands or millions of records during a search operation; see sorting algorithm.

The main purpose of sorting information is to optimise its usefulness for specific tasks. In general, there are two ways of grouping information: by category e.g. a shopping catalogue where items are compiled together under headings such as ‘home’, ‘sport & leisure’, ‘women’s clothes’ etc. (nominal scale) and by the intensity of some property, such as price, e.g. from the cheapest to most expensive (ordinal scale). Richard Saul Wurman, in his book Information Anxiety, proposes that the most common sorting purposes are Name, by Location and by Time (these are actually special cases of category and hierarchy). Together these give the acronym LATCH (Location, Alphabetical, Time, Category, Hierarchy) and can be used to describe just about every type of ordered information.

In computer science, a sorting algorithm is an algorithm that puts elements of a list in a certain order. The most-used orders are numerical order and lexicographical order. Efficient sorting is important for optimizing the use of other algorithms (such as search and merge algorithms) that require sorted lists to work correctly; it is also often useful for canonicalizing data and for producing human-readable output. More formally, the output must satisfy two conditions:

1. The output is in nondecreasing order (each element is no smaller than the previous element according to the desired total order)
2. The output is a permutation, or reordering, of the input.
The sorting discussed here are

1)Bubble sort

2)Insertion sort

3)selection sort

Only c++ Programs are available other sorting methods will be available soon .
