Wk 4 – Write a Ruby Program [due Mon]
Assignment Content
The college IT department manager no longer wants to use spreadsheets to calculate grades. The manager has asked you to create a program that will input the teachers’ files and output the students’ grades.
Write a Ruby program named formatfile.rb, which can be run by typing ruby widgets.rb.
In your Ruby environment, the program must read an input file formatted in CSV format, named input.csv. Each record contains data about a student and their corresponding grades.
The data will look similar to the following: Student Name, assignment1, assignment 2, assignment 3, assignment 4
John Adams, 90, 91, 99, 98
Paul Newman, 90, 92, 93, 94
Mary Smith, 95, 96, 99
Be careful to follow the output format exactly, including spacing. The output of your program must look like the following:
Student Assignment Average
John Adams 94.5
