Question about pseudocode for HW

I have the following question, and what I'm most confused on, is how to do the logic for determining if a check is one month late or not.

Question is:

"Write pseudocode for a program that calculates the service charge of a cust开发者_如何学运维omer owes for writing a bad check. The program accepts a customer's name, the date the check was written (year, month and day), the current date (year, month and day), and the amount of the check in dollars and cents. The program continues until an eof value is encountered. The service charge is $20 plus 2 percent of the amount of the check, plus $5 for every month that has passed since the check was written. A check is one month late as soon as a new month starts-so a bad check written on September 30 is one month overdue on October 1."

So far what I have write now is:

Start
  string Name
  num AmountOwed
  num DateCheckWritten
  num CurrentDate
  num CheckAmount
  get Name, DateCheckWritten, CurrentDate, CheckAmount
  while eof

Since you don't have to deal with days, the algorithm is very straightforward:

MonthsLate = (CurrentDate.Year - DateCheckWritten.Year) * 12 
                  + (CurrentDate.Month - DateCheckWritten.Month)

Good luck with the rest of the problem!

I'm not sure where your problem lies, but I think you have two issues to deal with:

1. What is the definition of late?
2. How many months late is this check?

So in my pseudocode, I would have a step that determines how late a check is, and then another step to calculate the fee. Inside the first step, you could just subtract the days and divide. But the directions say as soon as a new month comes along, it is one month late. So all you really have to do is subtract months.

Not sure what else you are asking, but it appears you are asking for guidance, not code. Hope this helps.

I'm going to assume this is homework, and as such I'll try to just point you in the right direction.

If you assign numbers to each month (Jan = 1, Feb = 2, etc) then the number of months between two dates is easy to determine - how many months are there between September (= 9) and May (= 5)?

The other thing to take into account is the year - for each year the check is late, you'll also have to add another twelve months. This works the same as for months.

Need any extra detail, feel free to let me know.

Simplify, hit the main points and then break it down more and more, write it how you would tell your grandma it worked.

you might start out with something like

Start
While there are more bad checks
  get the service charge 
  add the service charge to the account
record the updates

get the service charge
  charge starts at $20
  add to the charge $5 multiplied by number of months
