slice a valarray

<source lang="cpp">

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

using namespace std; int main() {

 valarray<int> v(10);
 for(int i=0; i<10; i++)
     v[i] = i;
 cout << "Original contents: ";
 for(int i=0; i<10; i++)
   cout << v[i] << " \n\n";
 valarray<int> result = v[slice(0,5,2)];
 cout << "Contents of result: ";
 for(int i=0; i<result.size(); i++)
   cout << result[i] << " ";

 cout << endl;

} /* Original contents: 0 1 2 3 4 5 6 7 8 9 Contents of result: 0 2 4 6 8
