Thread: Help me understand the program! pls

Are the array elements in order like is A[0] = 5? I'm trying to help but this might clear it up for me.

edit :
There is an error on (Int A[]){ it should be (int A[]){

--- Update ---

Alright so I ran the program (after making a main method for it) and here was the output:
Array in ascending order is ->
1
2
3
4
5
8
9
12
15
90
Then i had an exception in main with an out of bounds exception.(I don't know how exceptions yet. My fault coding the main method.) But as you can see it puts the numbers in order from least to greatest. I tried to trace the code (see how it worked) and goodness it was hard! Once I get a clear answer on how it works i'll tell you! Hope this helped!

As has been mentioned to you in the past, please use code tags when posting code, instructions can be found on the Announcements page. This is to preserve readability of the code for future readers, and to save time for the volunteers who help answer questions.

Have you tried to step through the code on paper? Start at the first loop, write out what happens in the background as the code progresses. You will easily see which elements of the array are being considered on each iteration of the loop. You will see when the conditional passes and which elements are swapped.

What did your favorite search engine say about bubble sort?

Hi, can you pass me the code you that you have altered. I guess it would be better to understand.

Hello.
Did you copy the code from internet?
If so then I would suggest you should first learn about bubble sort and write your own code. Initially it may look difficult.
But as you step in it shall become easier.

Hi Syed,

No, it was from one of the books i was referring to and i came across this program.
