![]() It can be optimized by using a flag variable that exits the loop once swapping is done. It is the slowest sorting algorithm and runs with time-complexity of O ( n 2 ) O(n^2) O ( n 2 ). ![]() Bubble sort gets its name from the fact that it filters out the elements at the top of the array-like bubbles on water. We repeat this until no more swaps are required, and all the elements get sorted. In Bubble sort in C, we compare two adjacent elements of an array to find which one is greater or lesser and swap them based on the given condition, whether ascending or descending, until the final place of the element is not found. We will be focusing on Bubble sort in C as we move through the course of this article. There are many sorting techniques defined in Computer Science domain: Bubble sort, Insertion sort, Selection sort, Quick sort, Merge sort, Radix sort, Bucket sort, etc. This is sorting.Įfficient searching and faster data processing are some of the key advantages of sorting. Taking a real-life example that is relatable to most readers when we play cards, we usually get shuffled cards, and thereby, we need to sort them suit-wise for easy access during the course of the game. From sorting TV channels based on audience viewing time to sorting the contact list of mobile phones alphabetically for easy access, sorting is used everywhere. There are many real-life scenarios where we need to sort and arrange the data in a specific order. It runs with the worst-case time complexity of O ( n 2 ) O(n^2) O ( n 2 ).īefore reading this article, you should have some understanding of the following C programming topics: In Bubble sorting, we compare two adjacent elements of an array to find which one is greater or lesser and swap them based on the given condition until the final place of the element is not found. Bubble sort in C is one of the easiest and basic sorting technique that is very easy to implement.
