The smallest element is bubbled from unsorted sublist. For example, the lower part of an array is maintained to be. The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted. Bubble sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in wrong order music.
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. Bubble sort is a simple sorting algorithm that works by repeatedly stepping through the list to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order.
