Multiplying the elements in v with those in v2

#include <iostream> #include <vector> #include <algorithm> #include <functional> using namespace std; int main() {   vector<int> v, v2, result(10);   for(unsigned i=0; i < 10; ++i) v.push_back(i);   for(unsigned i=0; i < 10; ++i) v2.push_back(i);   transform(v.begin(), v.end(), v2.begin(), result.begin(), multiplies<int>());   return 0; }
