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.

How to use document.write in JavaScript?

Hello guys, Today I am sharing very basic method of javascript which is "document.write()".
Using document.write you can write inside a html document using javascript.

A very basic hello world example is below:

<script type="text/javascript">
document.write("<p>Hello World</p>");
</script>

To understand document.write function in more depth, I am sharing few more simple usage of this function.

<script type="text/javascript">

var sampleText="Sample Example of Document.write function";

document.write("<p>"+sampleText+"</p>");

</script>

Printing date using document.write function:

<script type="text/javascript">

var sampleText="Sample Example of Document.write function";

document.write("<p>"+Date()+"</p>");

</script>

Using document.write function inside a function:

<script type="text/javascript">

function f1() {

document.write('hello world');

}

</script>

<script type="text/javascript">

f1();

document.write('Ba Bye');

</script>

Overriding whole document's content using document.write function:

<script type="text/javascript">

function f1() {

document.write('Some text');//for overwrite entire page content

}

window.onload = w1;

</script>
