// slice::size example
#include <iostream>
#include <valarray>
using namespace std;

int main ()
{
  valarray<int> foo (10);
  for (int i=0; i<10; ++i) foo[i]=i;

  slice slc (0,3,1);

  valarray<int> bar = foo[slc];

  cout << "slice with a size of " << slc.size() << ":\n";
  for (size_t n=0; n<bar.size(); n++)
	  cout << bar[n] << ' ';
