Arrays problem; quick question

Apr 18th, 2008

Hey there. It's Erinn and I just have a quick question about my assignment that I am working on. I have everything right except for one part...don't u hate that...lol. Anyway, here is the code and assignment below. Sorry there is no code, but it's been a long day and I'm tired.

The assignment is: Write a program which asks the user for a series of pairs of values: loanAmount and numMonths. There might be as many as 10 of these. After getting all of the input, print a list of the loans, the number of months, and the payment per month (no interest charged). For example:

Please enter a loan amount: 1000
Please enter the number of months: 10
Continue (yes/no)? yes
Please enter a loan amount: 999
Please enter the number of months: 30
Continue (yes/no)? yes
Please enter a loan amount: 1234
Please enter the number of months: 5
Continue (yes/no)? no
************************* <<- YES PRINT THESE ASTERISKS
There are 3 loans.
Loan 1 for $1000 for 10 months has a payment of $100 per month
Loan 2 for $999 for 30 months has a payment of $33.3 per month
Loan 1 for $1234 for 5 months has a payment of $246.8 per month
TOTAL MONTHLY PAYMENT: $380.1

Here is the coding I have. The only question I have is on the part where it says, "There are 3 loans." The part of the code I need help with is in bold. Again, everything I have works and is fine except how to do I properly write that calculation and do I place it there or before the while? I get three when I do this program, but when I just for the heck of it try additional ones other than 3, i just get 3. For example, the assignment says only three, but I try four, and I only get three and not four. Could someone help me with this part? Thanks
