  • Description

    Probably would be considered less clean than the parent, but also faster by avoiding streams.

     Code 
    #include <string>
#include <vector>

auto split(const std::string& str, char sep) {
  auto result = std::vector<std::string>{};
  std::string::size_type pos = 0, pos2 = 0;
  
  while ((pos2 = str.find(sep, pos)) != std::string::npos) {
    result.push_back(str.substr(pos, pos2 - pos));
    pos = pos2 + 1;
  }
  result.push_back(str.substr(pos));
  return result;
}
