20.4.2.Get elements less than a value

#include <iostream>

#include <valarray>

#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;

   

  valarray<bool> vb = v < 5;

  cout << "Those elements less than 5: ";

  for(i=0; i<10; i++)

    cout << vb[i] << " ";

  cout << endl << endl;

   

   

  return 0;
