It will divide an input list into two partsa sublist of items already sorted on the right side and a sublist of items remaining to be sorted in the rest of the list. Rather than sorting the structs themselves, create an array of pointers to the structs, and an appropriate comparison function that reads the appropriate values from the struct through the pointer, and sort the list of pointers. Each pass through the list places the next largest value in its proper place. Bubble sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are.
In this way, all the elements of the array get compared. Hence the algorithm is same with a mechanism to determine whether the listarray ds is sorted or not after every iteration.
