Using notes, write a program which will do the following: 

1. read in an unknown number of student records where you have - first name, last name, major, and GPA

2. Output all information to both the screen and to an output file

3. After reading in data, determine the average GPA for the class

4. Output the average GPA to the screen and the output file.
