Using a CSV of student names and assignment grades, and your code from yesterday's project, you will generate a report from a CSV. For example, given the following CSV:
Student,Project 1,Project 2,Quiz
Evelyn,90,95,85
Marley,80,85,90
Hayden,75,85,80
you should generate a report like the following:
Average by student:
Evelyn: 90 (A)
Marley: 85 (B)
Hayden: 80 (B)
Average by assignment:
Project 1: 81 (B)
Project 2: 88 (B)
Quiz: 85 (B)
Class average: 85
Files
Starter files have been provided in the 'starter_files' folder. gradebook.rb includes code to accept a filename on the command line, so you should be able to run ruby gradebook.rb input1.csv and see a report for input1.csv.
To run the tests to see if your code is correct, run ruby gradebook_test.rb.
