The types of sorting in C are listed below. 1. Bubble Sort. Bubble sort may be defined as the sorting algorithm that follows the approach of replacing the value in the first index with the smallest value in the array and keep it repeating until the list is sorted. It is a very simple way of performing sorting. http://mercury.webster.edu/aleshunas/COSC%205130/G-SDES.pdf how is opium taken
