Parse two lists of numbers and zip them into a vector of pairs

string_zipper.cpp

#include <iostream>
#include <sstream>
#include <vector>
#include <string>
#include <iterator>
#include <algorithm>

struct Pos{
  float x = 0;
  float y = 0;
};

int main()
{
  std::string x{"1.1 2.2 3.3 4.4 5.5"};
  std::string y{"5.5 4.4 3.3 2.2 1.1"};
  
  std::vector<Pos> nums;
  
  std::istringstream iss_x(x);
  std::istringstream iss_y(y);
  
  std::transform(std::istream_iterator<float>(iss_x), std::istream_iterator<float>(), std::istream_iterator<float>(iss_y), std::back_inserter(nums), 
    [](float x, float y)-> Pos {
      Pos pos{x,y};
      return pos;  
    });
  

  std::for_each(nums.begin(), nums.end(), [](const Pos& pos){std::cout << "(" << pos.x << ", " << pos.y << "), ";});
  
  std::cout << std::endl;
}

Only thing not really desirable is there's not a readily apparent way to check or flag if y ends up being shorter than x.
