c++ 容器切片反转次序（拷贝到新容器）

code:

// rotate_copy algorithm example
#include <iostream>     // cout
#include <algorithm>    // rotate_copy
#include <vector>       // vector
using namespace std;
int main () {
  int myints[] = {,,,,,,};

  vector<int> myvector();

  rotate_copy(myints,myints+,myints+,myvector.begin());

  // print out content:
  cout << "myvector contains:";
  for (vector<int>::iterator it=myvector.begin(); it!=myvector.end(); ++it)
    cout << ' ' << *it;
  cout << '\n';

  return ;
}

输出

myvector contains:
