rotate的用法

#include <iostream>
#include <algorithm>
using namespace std;
int main (void)
{
int iArray[] = {1, 3, 3, 7, 3, 0, 0, -7, 9, 3, 10};
rotate(iArray, iArray + sizeof (iArray) / sizeof (*iArray) / 2,iArray + sizeof (iArray) / sizeof (*iArray));
for (size_t i = 0 ; i != sizeof (iArray) / sizeof (*iArray) ; i++)
{
cout << iArray[i] << ' ';
}
cout << endl;
return 0;
}
