Question

Computing I Program 3 – Treat this like a take home exam. You may not work together. Write a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: Each line contains a student’s first name, then one space, then the student’s last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file.

Write a program to compute average grades for a course.  The course 
records are in a single file and are organized according to the following 
format:  Each line contains a student’s first name, then one space, then the 
student’s last name, then one space, then some number of quiz scores that, 
if they exist, are separated by one space.  Each student will have zero to 
ten scores, and each score is an integer not greater than 100.  Your 
program will read data from this file and write its output to a second file.  
The data in the output file will be nearly the same as the data in the input 
file except that you will print the names as last_name, first_name and 
there will be one additional number at the end of each line:  the average of 
the student’s ten quiz scores. 
 
The output file must be formatted such that first and last names appear 
together in a left justified column that is 20 characters wide where the last 
name comes first, then a comma and a space and then the first name.  Use 
your read string function to read each name separately and then put them 
together into a larger correctly formatted string before trying to output 
them.  Each quiz score should be listed in a right justified column that is 4 
characters wide, and the average should appear in its own right justified 
column that is 10 characters wide. 
 
Note that if a student has fewer than 10 scores, the average is still the sum 
of the quiz scores divided by 10; these students are assumed to have 
missed one or more of the quizzes. The output file should contain a line 
(or lines) at the beginning of the file providing appropriate column 
headings.  Use formatting statements to make the layout clean and easy to 
read. 
 
After writing the required data to an output file, your program will close 
all files and then copy the contents of the “output” file to the “input” file 
by reopening the input...
