数组排序

#include <iostream>using namespace std;void Sort(int ar[], int n){for(int i=0;i<n-1;++i){for(int j=0;j<n-i-1;++j){if(ar[j]<ar[j+1]){ int tmp=ar[j];ar[j]=ar[j+1];ar[j+1]=tmp;}}}}void main(){int ar[]={2,86,0,80,45,35,678,34,23,1256,78};int n=sizeof(ar) / sizeof(int);    Sort(ar,n);    for(int j=0;j<n;++j){ cout<<ar[j]<<"  ";}cout<<endl;}
