Hi. I was getting two error messages during one of the tests my school's
testbed program ran, so I tried to fix it, and I'm now getting some
results I never expected. Is my redesigned if statement toward the
bottom of the readFile function not right?

Starting Test 1
Here we will read the file that has the following text:
90 86 95 76 92 83 88 87 91 100
The sum is 888 so the average is 88.8%. You will need to round
correctly using the cout.precision() statement

Starting Test 2
this is the same as before except there is an extra newline at the

twice. If you do, the sum will be 988 which will yield 89.8%.

------------------------------------------------------------
Starting Test 1
Here we will read the file that has the following text:
90 86 95 76 92 83 88 87 91 100
The sum is 888 so the average is 88.8%. You will need to round
correctly using the cout.precision() statement
> Please enter the filename: /home/cs124/assignments/assign26a.txt
> Average Grade: 89%
Test 1 passed.
------------------------------------------------------------
------------------------------------------------------------
Starting Test 2
this is the same as before except there is an extra newline at the
end of the file. Your program will need to not read the last number
twice. If you do, the sum will be 988 which will yield 89.8%.
Read the section in the book titled "Reading to the end of the file"
for a discussion on why this might happen and how to fix it
> Please enter the filename: /home/cs124/assignments/assign26b.txt
> Average Grade: 89%
Test 2 passed.
------------------------------------------------------------
------------------------------------------------------------
Starting Test 3
This should yield an error because there are 12 items in the file
> Please enter the filename: /home/cs124/assignments/assign26c.txt
> Average Grade: 171%\n
Exp: Error reading file "/home/cs124/assignments/assign26c.txt"\n
Test 3 failed.
------------------------------------------------------------
------------------------------------------------------------
Starting Test 4
This should yield an error because there are 3 items in the file
> Please enter the filename: /home/cs124/assignments/assign26d.txt
> Average Grade: 2%\n
Exp: Error reading file "/home/cs124/assignments/assign26d.txt"\n
Test 4 failed.
------------------------------------------------------------
------------------------------------------------------------
Starting Test 5
This should yield an error because the file does not exist
> Please enter the filename: /home/cs124/assignments/assign26e.txt
> Error reading file "/home/cs124/assignments/assign26e.txt"
> Average Grade: -nan%\n
Exp: No output
Test 5 failed.
