Using C++ please

the original AL Weather Station Data file find all records that have a bad data flag (-9999) for either the PRCP, TMAX or TMIN fields. Produce a new data file (call it Filtered_AL_Weather_Station.txt ) that omits those records with bad data flags

Can somebody to give example to working on this question, thank you very much ; use of C++ please
