C program for Bubble Sort

Today I am going to share how to perform bubble sort in C programming language. What is Bubble Sort? Bubble sort is a very simple sorting algorithm which compares consecutive numbers and swap them if both are not in right order. This gives the biggest element at the end in each inner loop cycle. Here is an animated example for bubble sort:

#include
#include

  void bubbleSort(int arr[],int length)
  {
        int i,j,temp;
         for(i=length;i>0;i--)
         {
            for(j=0;j<=i;j++)
   { 
                if(arr[j]>arr[j+1])
                { 
//swap if previous value is bigger then next value
                    temp=arr[j];
     arr[j]=arr[j+1];
                    arr[j+1]=temp;
                }
   }// End of Inner For loop
        }// End of Outer For loop.
  }// End of BubbleSort Function
  


 void main()
 {

  
  int data[] = {4,3,5,2,9,2,1,8,7,0}
  int i;

  clrscr();

  printf("\nData before sorting: ");
  
  for( i=0; i<10; i++)
  { 
   printf("%d , ",data[i]);
  }
       
  bubbleSort(data,10);

  printf("\nData after sorting: ");
  
  for( i=0; i<10; i++)
  {
   printf("%d , ",data[i]);
  }
  
  } //End of this example.
