下面是冒泡排序算法的四种实现方式：C、C++、Java和Python。

C语言实现：

#include <stdio.h>void bubbleSort(int arr[], int n) {for (int i = 0; i < n - 1; i++) {for (int j = 0; j < n - i - 1; j++) {if (arr[j] > arr[j + 1]) {int temp = arr[j];arr[j] = arr[j + 1];arr[j + 1] = temp;}}}
}int main() {int arr[] = {64, 34, 25, 12, 22, 11, 90};int n = sizeof(arr) / sizeof(arr[0]);bubbleSort(arr, n);printf("排序后的数组：");for (int i = 0; i < n; i++) {printf("%d ", arr[i]);}return 0;
}

C++语言实现：

#include <iostream>
using namespace std;void bubbleSort(int arr[], int n) {for (int i = 0; i < n - 1; i++) {for (int j = 0; j < n - i - 1; j++) {if (arr[j] > arr[j + 1]) {int temp = arr[j];arr[j] = arr[j + 1];arr[j + 1] = temp;}}}
}int main() {int arr[] = {64, 34, 25, 12, 22, 11, 90};int n = sizeof(arr) / sizeof(arr[0]);bubbleSort(arr, n);cout << "排序后的数组：";for (int i = 0; i < n; i++) {cout << arr[i] << " ";}return 0;
}

Java语言实现：

import java.util.Arrays;class BubbleSort {public static void bubbleSort(int[] arr) {int n = arr.length;for (int i = 0; i < n - 1; i++) {for (int j = 0; j < n - i - 1; j++) {if (arr[j] > arr[j + 1]) {int temp = arr[j];arr[j] = arr[j + 1];arr[j + 1] = temp;}}}}public static void main(String[] args) {int[] arr = {64, 34, 25, 12, 22, 11, 90};bubbleSort(arr);System.out.print("排序后的数组：");System.out.println(Arrays.toString(arr));}
}

Python语言实现：

def bubbleSort(arr):n = len(arr)for i in range(n - 1):for j in range(n - i - 1):if arr[j] > arr[j + 1]:arr[j], arr[j + 1] = arr[j + 1], arr[j]arr = [64, 34, 25, 12, 22, 11, 90]
bubbleSort(arr)
print("排序后的数组：", arr)

以上是冒泡排序算法在不同语言中的实现，
