Abstract class: You can inherit only one class.
Interface: You can inherit more than one interface.
Abstract class: It contains both completed and uncompleted
(abstract) methods.
Interface: It only contains uncompleted methods (methods
without body).
Abstract class: Access modifiers are there for methods and
properties.
Interface: It does not have access modifier for methods or
properties. By default they are public.
Abstract class: Fast
Interface: Require more time to find actual method in classes.
Abstract class: It can contain fields and constants.
Interface: no fields can be defining in interface.

Write a program to compute for numeric grades for a course. The course records are in a file that will serve as the input file. The input file is in exactly the following format: Each line contains a student's first name, then one space, then ten quiz scores all on one line. The quiz scores are in whole number and are separated by one space. Your program will take it input from this file and sends it output to a second file. The data in the output file will be exactly the same as the data in the input file except that there will be one additional number (of type double) at the end of each line. This number will be the average of the student's ten quiz scores. Use at least one function that has file streams as all or some of its arguments.
