## INTRODUCTION:

Computer science relies heavily on sorting algorithms, and the C programming language provides a large variety of effective sorting methods. In order to arrange the components of a collection of data in a certain order, such as ascending or descending order, sorting algorithms are utilised. We will examine some of the most popular sorting algorithms in C programming in this article.

## Bubble Sort:

This straightforward sorting method swaps neighbouring elements repeatedly if they are in the wrong order. Because to its O(n2) time complexity, it is not suggested for use with large datasets.

## Selection Sort:

This algorithm sorts an array by continually selecting the first member that is least in the array’s unsorted portion. In addition, it has an O(n2) time complexity, yet it is more effective than bubble sort.

## Insertion Sort:

This algorithm inserts each piece into the appropriate spot before creating the final sorted array one item at a time. Compared to the first two methods, it is more effective and has an O(n2) time complexity.

## Quick Sort:

This sorting method is popular because it is quick and recursive. It separates the array into smaller subarrays and individually sorts each one. Its average time complexity is O(n log n), while its worst case is O(n2).

## Merge Sort:

It divides an array into two halves, sorts each half separately, and then merges the sorted halves. This is another effective divide-and-conquer method. It is stable and has an O(n log n) time complexity.

## Heap Sort:

This is an effective in-place sorting technique that sorts an array using a binary heap. It is unstable and has an O(n log n) time complexity.

## CONCLUSION:

In summary, sorting algorithms are a crucial component of computer science, and the C programming language provides a large variety of effective algorithms for sorting data. The size of the dataset, the desired level of stability, and the needed level of time complexity all influence the algorithm of choice. Understanding the fundamentals of sorting algorithms in C programming allows you to select the optimal algorithm for your particular use case and efficiently optimise your code.
