The condition of a stream is equivalent to !fail(), which means set either failbit or badbit will terminate the loop. For example, errors list below will terminate the loop:
- System-level failure. (Set the
badbit) Such as an unrecoverable r/w error. - Recoverable error. (Set the
failbit) Such as reading a character when numeric data expected. - Reaching end-of-file. (Set both the
eofbitandfailbit)
