c++将冒泡排序定义成函数文件

#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 << "Sorted array: \n";
  for (int i = 0; i < n; i++) {
    cout << arr[i] << " ";
  }

  return 0;
}
