I have this program for computing an individual's cable bill, then summing each column of values and calculating the average of each column. I got a 100 on the assignment, the program works fine, but this time we have to use functions. I created my functions and the program, again, works fine. Only problem is I have to convert money values into integers for dollars and cents and print them explicitly.
My problem is I don't know where to keep money values in doubles and when to actually convert them to integers. Ugh, this is so frustrating.
