How to Implement Shell Sort in C Programming?

Shell Sort (aka shellsort) can be thought as an improvement over insertion sort. To understand shell sort, we have to recall how insertion sort works. In insertion sort at any moment, the whole array is sub-divided in two sections, one is sorted and another is not. One element is picked from the unsorted section and compares with the … Continue reading “How to Implement Shell Sort in C Programming?”

How to Implement Quick Sort in C?

Quick Sort is an efficient sorting algorithm developed by Tony Hoare in 1959. It is still a commonly used sorting algorithm in most practical cases. If implemented properly, it is two or three times faster than other efficient sorting algorithms like merge sort or heap sort. Here we’ll see how to implement this sorting algorithm … Continue reading “How to Implement Quick Sort in C?”

How to Implement Merge Sort in C?

Merge sort is efficient, general-purpose sorting algorithm. Unlike bubble sort or insertion sort, it is usable in most practical cases. Merge sort is divide and conquer algorithm. Here we’ll see how to implement merge sort in C programming language. We’ll also analyze its performance in various conditions. Merge Sort Algorithm Merge sort is divide and … Continue reading “How to Implement Merge Sort in C?”

How to Implement Bubble Sort in C Programming?

Bubble Sort is very popular sorting algorithm in computer programming. Its popularity is not for its performance but for its simplicity. In fact bubble sort is not suitable for most of the practical cases because of its inefficiency. But it very easy to understand and code compare to other sorting algorithms like quick sort or merge … Continue reading “How to Implement Bubble Sort in C Programming?”

How to Implement Insertion Sort in C Programming?

Insertion sort is one of the most popular sorting algorithms. Its popularity is not because of its performance but for its simplicity. Its performance is not as good as quicksort or shellsort for large number of inputs but it is very simple like bubble sort. It is often used for less number of elements especially when the … Continue reading “How to Implement Insertion Sort in C Programming?”
