Netpay Average

LaC0saNostra (82)
I've been working on this program for a month now and have it executing. The last thing I need to do is calculate the average netpay for my 5 employees from my "employee.txt" file which I have included in the program which looks like this:

8572 40 12.00
6423 40 15.00
7465 40 10.00
2477 40 16.00
5996 40 18.00

Then I want it to display into my program. Any suggestions on how to do this? I can't find it in this handbook I have for C++

printalldata() doesn't work? What do you want to display?

Well I believe I need some sort of function that adds up the net pays and then finds their average. Then I want to display it when my program executes. Is there a way to do that?

This is what I have now still with some errors:

Actually I figured it all out, but thanks for posting. I had to add the totalNetPay +=netpay[i] code outside of the parenthesis in the for code and then it worked. Thanks though for posting
