sort的用法

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;

bool cmp(int i,int j){
    return (i>j);
}

struct myclass {
  bool operator() (int i,int j){
      return (i>j);
  }
}myobject;

int main () {
  int myints[] = {32,71,12,45,26,80,53,33};
  vector<int> myvector (myints, myints+8);               
  vector<int>::iterator it;
  //sort (myvector.begin(), myvector.end(), cmp); 
  sort (myvector.begin(), myvector.end(), myobject);     
  cout << "myvector contains:";
  for (it=myvector.begin(); it!=myvector.end(); ++it){
     cout << " " << *it;
  }
  cout << endl;
  return 0;
}
