First of all: Thanks for taking time to help!
I have 2 programs that are accessing one text file.
The first one is supposed to take in the quarterly sales figures for each of the four divisions of a company.
The second one is to display the report.
My problem is the output of the second file:
Every item is:
-9.25596e+061
I am trying for a while now to figure what I'm doing wrong.
Could it be the file path? After running the first program, I tossed the text file in the solution folder of the second program. Thinking it should find it.
Or do I mix up reference and value? I tried to change the & to a * but that broke the code.
Here is the code that writes to the file.
