In this compliant solution, each converted value read from the standard input stream is tested for validity before reading the next value in the sequence, allowing error recovery on a per-value basis. It checks std::istream::fail() to see if the failure bit was set due to a conversion failure or whether the bad bit was set due to a loss of integrity with the stream object. If a failure condition is encountered, it is cleared on the input stream and then characters are read and discarded until a ' ' character occurs (space) character occurs. Note that the error handling in this case only works if a space character is what delimits the two numeric values to be converted.
