Thread: need to figure how this thing will work

my advisor told me that " INPUT FROM A FILE,IT SHOULD HAVE MORE THAN ONE BIRTHDAY AT OUTPUT ALSO TO A FILE"

hello sir good evening. im not quite sure about this actually my professor told me that, "INPUT FROM A FILE,IT SHOULD HAVE MORE THAN ONE BIRTHDAY AT OUTPUT ALSO TO A FILE" im pretty sure the program is working, but when she told me that, that's the time i was lost with it. now im totally lost with it. =(

So it's suppose to read multiple birth dates from a file. And then output them with their zodiac in a different file?

yes sir @hallowed
