Implementation of Quick SortAlgorithm in C2 min read

In this tutorial, we will write a C program to implement quick sort. Before that, you may go through the following topics in C.

Quick Sort Algorithm

Quicksort algorithm is a way of rearranging the elements in an array in ascending or descending order. Quicksort is another Divide and Conquer algorithm.

It takes two empty arrays to hold elements, the first is less than the pivot value and the second element greater than the pivot value, and then sort the element around it or inside it. It involves Swapping and partitioning a section of the array.


Implementation of Quick SortAlgorithm in C

Question: C program to implement Quick sort using function.

Output:

Enter the number of elements: 6
Enter 6 Elements:
12
65
5
224
68
45

Array after sorting:
5 12 45 65 68 224

Time Complexity of Quick Sort:

  • Best case:  0(n log n)
  • Average case:  0(n log n)
  • Worst case:  0(n^2)
