Write a c program to implement bubble sort using arrays

Worst case scenario occurs when the array is in the opposite order that we are doing sorting for. Three passes will be required. The process has to be repeated again to bring the next lower value to last but one position. Best case scenario occurs when the array is already sorted at the beginning.

Thus, if n is the number of elements in the array, the process of comparison will be repeated n-1 times. The elements with higher values will move back, while elements with smaller values will move to the front; the smallest element will become the 0th element and the largest will be placed at the end.

There exist many sorting algorithms, such as merge sort with substantially better worst-case or average complexity of O n log n.

And again it is to be repeated to place the next largest value at the proper position. This is the most optimized implementation of bubble sort as per the number of comparisons is concerned.

Bubble sort has worst-case and average complexity both n2where n is the number of items being sorted. The comparison then shifts to the next element and so on up to the end of the array. The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted.

Other 3 variation take equal number of comparisons but less than the first variation. If we double the number of inputs, the number of comparisons becomes four times. From the graph we can see the the first variation takes maximum number of comparison.

The mechanism of sorting is explained below. The above diagram show how our 4 implementations perform in worst case scenarios. If we double the number of inputs then the number of comparisons will become four times. Next time the inner loop will go up to newn.

C program for bubble sort

Worst case running time of bubble sort in Big-O notation is O N2. In this way, the element with the highest value goes to the end. Array Suppose, we want to sort an array in ascending order. Therefore, bubble sort is not a practical sorting algorithm when n is large. The output is given after each round of comparisons and swapping to make it illustrative, otherwise, output after every round of sorting is not necessary.

Bubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that repeatedly steps through the list to be sorted, compares each pair of adjacent items and swaps them if they are in the wrong order.

In the first round only one value, i.

We should notice one important thing here that growth rate of all four variations is same. Even other n2 sorting algorithms, such as insertion sort, tend to have better performance than bubble sort.

The growth rate of third and fourth variations is linear. An example of bubble sort.

But here also the growth rate of running time or required comparison is same, i. Average case running time of bubble sort in Big-O notation is also O N2.We have already implemented Bubble sort without using Function Templates.

Template is a powerful feature of Object oriented programming. They give the flexibility to a programmer for using any data type in a function without rewriting the whole boring function for each data type again and again.
