c++ - Replace 'for loop' using std::for_each -

i have loop in below code , implement using std::for_each. have implemented it. please tell me if best way using std::for_each? if not, please suggest right one?

#include <vector> #include <cstdint> #include <string> #include <algorithm> #include <iostream> #include <sstream>  int main() {     std::vector<std::uint32_t> nums{3, 4, 2, 8, 15};     std::stringstream list1;       (auto n : nums)     {         list1 << n<<",";     }      //is right way using std::for_each above loop can done in 1 line??     std::for_each(nums.begin(),nums.end(),[&list1](std::uint32_t n){ list1 << n << ","; });  } 

yes, use of for_each reasonable analog of preceding loop.

i feel obliged point out, however, find for_each least useful algorithm in library. i've seen, using indicates you're still thinking in terms of loops, , changing syntax use loops. think range-based for loops have eliminated @ least 90% of (already few) legitimate uses there used for_each.

in case, code imitating using std::copy std::ostream_iterator:

std::copy(nums.begin(), nums.end(),            std::ostream_iterator<std::uint32_t>(std::cout, ",")); 

even this, however, clumsy enough think it's open question whether it's improvement on range-based for loop.
