Array-Mortgage Calculator

[phjones]

This is not a class project.The program below is to display mortgage interest paid for each payment over the term of the loan and loan balance.It is program using array. However, I am receiving the following error message:

I see that you had gotten help when you were working on this in Java.
Please read the posting guidelines (on the right while you are posting) to learn what CODE tags look like:

code should look like this

and try posting in the C++/C forum for help with this. Thanks.
