Sorting is arranging the given list in ascending/descending order, with respect to a given key field. This list can be number of records, with each record having many fields.

Types of sorting

  • Exchange/Bubble Sort
  • Selection Sort
  • Insertion Sort
  • Quick/Partition Exchange Sort
  • Merge/2-Way Merge Sort

Exchange/Bubble Sort : It uses simple algorithm. It sors by comparing each pair of adjusent items and swaping them in the order .This will be repeated until no swaps are needed. The algorithm got its name from the way smaller elements "bubble" to the top of the list.

It is not that much efficient, when a list is having more than a few elements. Among simple sorting algorithms, algorithms like insertion sort are usually considered as more efficient.
Bubble sort is little slower compared to other sorting techniques but it is easy because it deals with only two elements at a time.

An example to bubble sort is given below.

#include <stdio.h>
void main()        
    int a[10]={34,2,56,78,34,5,76,10,47,29};  //initializing array of elements
    int n=10;
    int i,j,temp;
    for(i=0;i<10;i++)            //for loop to select each element in the array
        for(j=0;j<n-i;j++)      //for loop to swap elements after comparing
                temp=a[j];       //swaping
    for(i=0;i<n;i++)           //for loop to print sorted elements
        printf("%d \n",a[i]);

Pls explain me bubble sort with an example not by programming language.
