Moving functions & main() code to void generateReport()

aardalde (23)
"You'll need to print out the yearly profits in generateReport() along with everything else (that's the only way to get it to appear all together) - so make sure you run calculateYearlyProfits() before calling generateReport() (then it'll have the data ready to print!)"

I just don't know how to move the needed code into generateReport(). Thank you.

Have you studied structures and classes yet?

I just don't know how to move the needed code into generateReport().


What have you tried?

Have you tried to just cut and paste all the cout statements into the function?

By the way none of the other functions should have any cout statements.

Since you're using arrays how are you insuring that your data entry loop doesn't overflow the bounds of your arrays?

The basic instruction is to turn your main() function into generateReport(), and write a new main() function that calls generateReport().

[edit] Not all of main(), of course. Only the stuff that produces the report, lines 37–70.
