This program is from the collopy book. I just had to type it in and create a text file so it would compile correctly for a class assignment which I did. But the very last record will not be shown when i compile.
This is what is in the txt file:
Kelly Antonetz 70 50 98 80 65 85
Robert Cain 97 82 79 73 94 62
Karen Dehvae 81 87 94 85 93 89
Barry Harmo 76 77 80 81 75 92
Katrina Long 99 93 89 83 94 90
Amanda Mohr 65 67 71 84 88 96
Mike Revell 90 87 78 52 76 89
Woody Synder 76 76 83 85 77 81

}How can I get the last record to be outputted? any help would be great!
When I compile in in visual c++ it only shows up to Mike revell and his test grades and average
