Hello friends, hope you are doing good. In this tutorial, I am going to share a c ++ program to sort the element using bubble sort algorithm.
Bubble sort is the very simple sorting algorithm and it is a comparison-based algorithm in which each pair of adjacent elements compared and then elements are swapped if they are not in sorted in order. If you a college student or just started learning the c++ programming language, then this program will help you more to the better understanding of bubble sort.
Below is the algorithms to sort the number using Bubble sort.
1 2 3 4 5 6 7 8 9 10 11 | begin BubbleSort(list) for all elements of the list if list[i] > list[i+1] swap(list[i], list[i+1]) end if end for return list end BubbleSort |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 | #include <stdio.h> void swap(int *xp, int *yp) { int temp = *xp; *xp = *yp; *yp = temp; } void bubbleSort(int arr[], int n) { int i, j; bool swapped; for (i = 0; i < n-1; i++) { swapped = false; for (j = 0; j < n-i-1; j++) { if (arr[j] > arr[j+1]) { swap(&arr[j], &arr[j+1]); swapped = true; } } if (swapped == false) break; } } void printArray(int arr[], int size) { int i; for (i=0; i < size; i++) printf("%d ", arr[i]); printf("n"); } int main() { int arr[] = {64, 34, 25, 12, 22, 11, 90}; int n = sizeof(arr)/sizeof(arr[0]); bubbleSort(arr, n); printf("Sorted array: \n"); printArray(arr, n); return 0; } |
Sorted array:
11 12 22 25 34 64 90
