Implementation of HeapSort Algorithm in C2 min read

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

Heap Sort Algorithm

Heap is a tree in heap sorting that possesses some specific properties whose value should be greater than or equal to that of the children node.

Heapsort is a comparison-based sorting algorithm and is also considered as the improved Selection sort. It is based on a Binary Heap data structure so to understand we must know two types of data structure:
Arrays and trees

Binary heap
