Error Check & Total Sum Help!

rjohn103 (3)
I am new to C++ programming so please bare with me. I have two easy questions. 1) I am attempting to calculate the total sum for all values that appear under my "Interest" column.


2) When I compile the below code, the program ends at INPUT AND OUTPUT TEXT FILES WERE OPENED SUCCESSFULLY. I figure its a loop issue but am not sure of how to correct this. I need the INPUT AND OUTPUT TEXT FILES WERE OPENED SUCCESSFULLY.

That's what I thought initially, but when I changed it to 0, the same thing occurred. I even tried to remove the return 1 altogether, and the same issue occurred

When you open a new file it has nothing so it is at the end. ( I think)

Why open file for output if you don't use it?

I didnt add my fout statements yet, even though the output file is currently blank, there is an output text file and it does open successfully.
