include <iostream>


int main(int argc, char* argv)
{
  if (argc==1)
  {
    std::cout << "No parameters given at startup." << std::endl;
    std::exit(1); //Returns with an error message
  }
  else
  {
    std::cout << "parameters given at startup: " << argv[1] << std::endl;
  }
  //Returns without an error message
  //Equivalent to std::exit(0)
