I did it's the void poIndeksu ; in my. First the 1 and 3 would be compared and switched, then the 4 and 5.

On the next pass, the 1 and 2 would switch, and the array would be in order. Both worst case and average case complexity is O n 2 , where n is the number of items. Below is the source code for C Program to implement Bubble Sort using Array which is successfully compiled and run on Windows System to produce desired output as shown below :.

Keep in mind that the above function sorts the array in increasing order. Load Comments. Toggle navigation Home. Blog Contact About. Home C Programming Examples C Program to sort an array in ascending order using Bubble Sort C Program to sort an array in ascending order using Bubble Sort Last updated on September 23, Bubble Sort Bubble sort is a simple method that sorts the elements of an array into either increasing or decreasing order. The following are the steps to sort an array of size N in ascending order using bubble sort: Passthrough 1 : Compare arr[0] with arr[1].

Compare arr[1] with arr[2]. After, the first passthrough, the highest value in the array will be at the end. Passthrough 2 : Compare arr[0] with arr[1].

Passthrough 3 : Compare arr[0] with arr[1]. Let's take an example. For this example, we will follow the same method as in the previous example. The only difference is that we will replace the for loop with the nested while loop. In this C program for bubble sort, we will create a user-defined function and write down the mechanism of sorting the array elements inside it.

In this C program for bubble sort, we have used C pointers. All we did was create another user-defined function to standardize the use of pointers in it. All the elements are compared in standard bubble sorting even if the last elements are already sorted based on the previous iterations. This increases the execution time, which can be reduced by optimizing the C program for bubble sort.

The variable Swap is set as true if the swapping of elements has occurred; otherwise, it is false. When the program finds that the value of the Swap variable is false, it will understand that the sorting is already done and break out of the loop. This will reduce the execution time by optimizing the algorithm.
