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.
