slice::stride

public member function
size_t stride() const;

Return stride of slice

Returns the separation of the elements in the valarray that are selected as part of the slice.

Parameters

none

Return value

The stride of the slice.
size_t is an unsigned integral type.

// slice::stride 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 (0,5,2);
  valarray<int> bar = foo[slc];
  cout << "slice with a stride of " << slc.stride() << ":\n";
  for (size_t n=0; n<bar.size(); n++)
	  cout << bar[n] << ' ';
  cout << endl;
  return 0;
}


Output:

slice with a stride of 2:
0 2 4 6 8
