1. The problem statement, all variables and given/known data:
Using "filename" as the input, write an awk script that will find the sum and average of each user's grade and display them after their names in order. Also display the average of all the users at the end of your output.
"the file"
Bred Lerry 89 34 92 78 100 80
Farla Moran 71 73 38 98
Ed Morton 89 74 85 78
Ted Nifle 83 78 56 90
Ed Norton 67 78 92 34
Ivana Notrump 92 81 85 94

George Berry 86 84 76 78
Bob Marly 78 85 71 77 80
Ed Fible 67 89 90 95
"end of file"
2. Relevant commands, code, scripts, algorithms:
I can use awk, if statements for loops and while loops but they all have to be used with awk.
3. The attempts at a solution (include all code and scripts):
attempt 1
and I really don't understand the items++. I believe that the data +=i is putting the result of $i in that right? but I don't understand where the items come into play.
second attempt
If I could get a little help here that would really make my day. I've been racking my brain about this for two days and all the information that I have found on the Internet has just really confused me further. All I got in class was some sample awk scripts to look over and they did not explain to much. So if anyone can help me understand this that would be great thank you.

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
