Use a binary function object in list 'transform'


#include <iostream>
#include <list>
#include <functional>
#include <algorithm>
using namespace std;

int main()
{
  list<double> vals;
  list<double> divisors;
  int i;

  for(i =10; i <100; i+=10) 
     vals.push_back((double)i);
  for(i =1; i <10; i++) 
     divisors.push_back(3.0);

  cout << "Original contents of vals:\n";
  list<double>::iterator p = vals.begin();
  while(p != vals.end()) {
    cout << *p << " ";
    p++;

  cout << endl;
 
  p = transform(vals.begin(),

                divisors.begin(), 
                vals.begin(),
