program crashes on closure.
ok the HW assignment i was working on i got it back and it crashed on closure. guess why cause i had put the cin.get() at the end and always just exited by clicking x so it just never occured to me it wasnt working. so of course the teacher hit enter and it died trying to close.
so i have no idea why a program would execute just fine and THEN die trying to close. the little bits of commented out code here and there was me trying to fix the problem where it reads the first bit of data in the file then skips over the second one so thats why.
but mainly why does it die closing?
(yes i know this is my whole assignment but eh not sure what part is killing it)
