C++实现冒泡排序并打印输出

#include<iostream> using namespace std; void bubbleSort(int *arr,int len){ int temp; for(int i = 0;i<len-1;i++) for(int j = 0;j<len-i-1;j++){ if (arr[j]>arr[j+1]){ temp = arr[j]; arr[j] = arr[j+1]; arr[j+1] = temp; } } } void printArr(int *arr,int len){ for(int i = 0;i<len-1;i++) cout<< arr[i]; } int main(){ int arr[] = {4,2,8,0,5,7,1,3,9}; int len = sizeof(arr)/sizeof(arr[0]); bubbleSort(arr,len); printArr(arr,len); system("pause"); }
