std::vector<std::string> SplitString(const std::string& source, const std::string& spliters)

  const std::regex r{ spliters };

  std::sregex_token_iterator begin{ source.begin(), source.end(), r, -1 };

샘플 코드

int main()
{
  std::string str = "cat dog melon";
  auto strs = SplitString(str, " ");
  
  for(const auto& str : strs)
  {
    std::cout << str << std::endl;
  }

  return 0;
}


output >>
