Hello, I'm supposedto write a program that checks to see if the file exists and displays the file contents. Additionally, three statistics need to be computed and displayed. The program needs to count the number of records, compute the meanAge and the meanGPA for each student.

Both meanAge and meanGPA need to be displayed rounded off to three digits beyond the decimal point.
Thisis what I have so far, and I'm wondering if I'm on the right track. I'm a little bit confused on how I can acess every other three lines and then either convert them to a double or int. When I run this program, it gives me a compile error. Any help will be greatly appreciated!

Never mind, I have got it converted to ints and doubles


Also, I have a question, if I want to count the number of time that it diplays name, I know that I can use a for loop.


What would be my upperbound though?
Thanks in advance!

Since you don't know an upperbound, this might indicate that you CAN'T use a for loop (at least not how they are meant to be used). Instead you might want to find a way to do it with a while loop instead.
