The first line is a header. The records contain Last Name, First Name, Active/Inactive file and several test scores. Ignore the heading line. For each Active student calculate their average grade for each student printing out the Students First Name followed by Last Name and average score. Display a heading at the beginning with a name for the report and headings for the columns of Name and Average. After all students have been processed display the number of active students and the average class test score. Format the output so that only 1 digit after the decimal point is shown and the averages scores line up on the decimal points. In this file, for example, the gawk program should print the following: $ gawk -f minor1.gawk grades.txt Student Average Test Scores Name Average John Smith 96.3 Sally Clark 50.0 Lucy Ball 100.0 Mark Bently 66.7 4 Students with average score of 78.2 Using gawk a) Consider a file containing grade test grades for students called grades.txt file: Last, First, A/I, Test1, Test2, Test3 Smith, John, A, 90,100,99 Ballard, Sue, I, 15,,50 Clark, Sally, A, 100,50, Koen, Jack, I, 90,100,99 Ball, Lucy, A, 100,100,100 Bently, Mark, A, 100,,100 The file is comma delimited.
