1. Input names of students from the user, terminated by ZZZ, and create a data file GRADES with records of the form:
student (string), test1 (integer), test2 (integer), test3 (integer) In this file, all test scores should be set equal to 0.
2. Display the contents of the file GRADES created in Problem 1. Each student's record should appear on a separate line and include the total score (the sum of the three tests) for that student. For example, a line of output might be: R.Abrams 76 84 82 242
