Re: Adding two STL vectors

#include <iostream>
#include <vector>
#include <iterator>

using namespace std;

int main(int argc, char *argv[])
{
   if (argc < 2) {
       cout << "invalid number of args: " << argc << endl;
       exit(1);
   }

   vector<int> v1;
   vector<int> v2;

   v1.push_back(5);
   v2.push_back(6);
   v2.push_back(7);

   for (int i = 0; i < atoi(argv[1]); i++) {
       // Alternative 1
       //v1.insert(v1.end(), v2.begin(), v2.end());

       // Alternative 2
       v2.resize(v1.size());
       std::transform(v1.begin(), v1.end(), v2.begin(), v2.begin(),
plus<int>());
   }

   return 0;
}
