Shift content in a valarray

<source lang="cpp">#include <iostream>

1. include <valarray>
2. include <cmath>

using namespace std;

int main() {

 valarray<int> v(10);
 int i;
  
 for(i=0; i<10; i++) v[i] = i;
  
 cout << "Original contents: ";
 for(i=0; i<10; i++)
   cout << v[i] << " ";
 cout << endl;
  
 v = v.cshift(3);
  
 cout << "Shifted contents: ";
 for(i=0; i<10; i++)
   cout << v[i] << " ";
 cout << endl;
  
 return 0;
