{
if (ios.good()) {
std::cout << "ios.good" << std::endl;
} else if (ios.eof()){
std::cout << "ios.eof" << std::endl;

//prints the error flags when an attempt to open a file fails
void util::print_state (const std::ios& stream) {
cerr << " good()=" << stream.good();
cerr << " eof()=" << stream.eof();
cerr << " fail()=" << stream.fail();
cerr << " bad()=" << stream.bad();
