Comparison sorts | Sorting algorithms
A comparison sort is a type of sorting algorithm that only reads the list elements through a single abstract comparison operation (often a "less than or equal to" operator or a three-way comparison) that determines which of two elements should occur first in the final sorted list. The only requirement is that the operator forms a total preorder over the data, with: 1. * if a ≤ b and b ≤ c then a ≤ c (transitivity) 2. * for all a and b, a ≤ b or b ≤ a (connexity). It is possible that both a ≤ b and b ≤ a; in this case either may come first in the sorted list. In a stable sort, the input order determines the sorted order in this case. A metaphor for thinking about comparison sorts is that someone has a set of unlabelled weights and a balance scale. Their goal is to line up the weights in order by their weight without any information except that obtained by placing two weights on the scale and seeing which one is heavier (or if they weigh the same).

Using the C library qsort function
The C standard library comes with a sorting function called qsort. It uses quicksort, which is much faster than the simpler Bubble Sort. In this video we'll learn how to call the qsort from your program and how to write the comparison function that it needs to be able to sort any kind of a

C Programming: sorting an array with bubble sort and quicksort (qsort)
In this session we will learn how to sort an array using bubble sort and the built-in quicksort function qsort. We will do an array of floats, an array of strings, and an array of structs.
