C++0x lambdas:

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
   double sum = 0.0;
   int factor = 10;

   std::vector<double> v(3);
   v[0] = 1.0; v[1] = 2.0; v[2] = 3.0;
   std::for_each(v.begin(), v.end(), [&](double num){
       sum += factor * num;
       std::cout << "Summed: " << sum << std::endl;
   });
   return 0;
}
