about bubble sorting

A Google Search with keywords bubble sort source code returns links to several web sites that show the Bubble Sort source code. Below are just three of them.

Note that a Bubble Sort performs less than optimally. A better sort algorithm is Shell Sort. Many years ago, I did some testing and found that for any more than 12 items, bubble sort performed worse than Shell Sort. It may be different today but bubble sort would not be my choice for a sort algorithm.
