Bubble Sort It’s a sorting algorithm, in which each pair of adjacent items are compared and swapped if they are in wrong order. The comparison is repeated until no swaps are needed, indicating that the list is sorted. The smaller elements ‘bubble’ to the top of the list, hence, the name Bubble Sort. In this like selection sort, after every pass …

Bubble Sort - C Program Source Code

/* Logic : Do the following thing until the list is sorted
            (i) Compare two adjacent elements and check if they are in correct order(that is second one has
                to be greater than the first). 
            (ii) Swap them if they are not in correct order.
