Summary: I have a file to read multiple lines of multiple doubles from. Then, those values have to be rewritten to another file, along with text saying some calculations were a success or not (outputting "yes" or "no" to the outFile). My problem is that either the inFile is not advancing to the next line after reading the last value from the first line, or my while loop is only iterating once, OR there's some weird buffer thing going on. My outFile has all the correct test data for the first line, but there's only one line when there should be multiple.
