while (inData)


{








msum = ('m' + malegpa);





fsum = ('f' + femalegpa);





if (femalegpa == 'f')





fcounter++;





if (malegpa == 'm')





mcounter++;





msum = ('m' + malegpa);





fsum = ('f' + femalegpa);








}

A few little problems there. The main one is that your inData reads are outside the loop so only the first line of data is read. Also your syntax seems to add characters and doubles which may be legal C++ it is a meaningless thing to do. Oh heck, you also forgot to initialize msum and fsum.





Also are the male, female data lines interleaved? I suspect not. You want to read a line then sort which type it is.
