Assignment Help:

Write an AWK program which takes the following input file and processes it.

$cat data.txt
John Do 111-1111 English 90 Maths 80
Alice Do 222-2222 English 90 Maths 90 Chemistry 93

The input file has first 3 fields fixed as first name, last name, and student id. After the student id, it has a variable number of fields which has a pair of name of a subject and points scored in that subject. Your output should print the full name of the student, number of subjects taken, and his/her average score. The output corresponding the above input file is as follows:

$awk -f avgerage.awk data.txt

John Do: 2 subjects taken, average = 85

Alice Do: 3 subjects taken, average = 91
