Depending on the parsing state, failbit may or may not be set at the same time: for example, int n istringstream buf ( "1" ) buf > n sets eofbit, but not failbit: the integer 1 was successfully parsed and stored in n. The numeric input overloads of basic_istream::operator> if the end of the stream was encountered while reading the next character, on Stage 2 of num_get::get processing.The string input function std::getline if it completes by reaching the end of the stream, as opposed to reaching the specified terminating character.The eofbit is set by the following standard library functions:
