Generate 10 random numbers (1-100) using bubblesort

Re: Generate 10 random numbers (1-100) using bubblesort
 

Well, and your question is... ???

Re: Generate 10 random numbers (1-100) using bubblesort
 

When I run the program it appears:
83 86 77 15 93 35 86 92 49 21
83 77 15 86 35 86 92 49 21 62

It is clearly not sorted and 93 appears on the first output but not the second, and 62 is in the second output but not the first. Why is it doing this ?

It's a shame you didn't add the code tags.

"Hey, I know, lets piss off all the people who help around here by continually posting unindented crap."

Doesn't work kiddo. Either we ignore you, or just report the post and wait for a mod to show up in a few hours. Then, if we're still interested, we might just get around to looking at your missive.

Either way, what could have been answered straight away is now delayed until your post gets fixed.

how do i indent ? i press tab and it just tabs over to the reply button

Re: Generate 10 random numbers (1-100) using bubblesort
 

Indent using the space bar.

And the simplest form of using code tags is

[code]
your code here ...
[/code]

I see.

Re: Generate 10 random numbers (1-100) using bubblesort
 

If you don't use code tags, the indentation simply gets lost.
