SAMPLE OUTPUT ::

****************************************************
This program sorts numbers in increasing order
using bubblesort technique
****************************************************
Enter how many numbers you are going to enter for sorting ::7
Now enter your elements ::
1.7
1.6
1.5
1.4
1.3
1.2
1.1
Now the sorted numbers are ::
1.1 1.2 1.3 1.4 1.5 1.6 1.7
