calculate grades

Description:

You have just completed one semester of working as a Computer Science TA for the Winter 2003 semester. Throughout the past year you have been marking assignments and quizzes. It is now time to complete your grading and submit the final marking sheet to your supervising professor. You have your assignment marks calculated and ready to submit; however, you still have a bunch of quiz grades that need to be marked and calculated.

The quizzes you are for multiple choice test and are in the form of:

TTFTFTTTFF Tino Duong

FTTFTFTTFT John Smith

FTFTFTTTFF Ted Jones

FTTFTTTTTT Jen Wilkins

TTFFTFFTTT Thom York

TTFTFTTTFF

Where each row contains the first and last name, preceded by the answers students answers to the quiz. The very last line is the answer key.

Your job is to write a program that will take a text file in this format and process it to give you final grades.

Requirements:

• Take in the name of the file that is to be marked using command line arguments. Usage should be in the format

    ./a.out <input file>

-Where a.out is the executable
- input file, is the name of the file to be processed

• Output a the solution to a file named data.txt
• Allow the program to accept input files, with an unlimited number of students

For each file that is marked.

• Give a percentage grade for each student
• Give the total number of students
• Give the total number of correct answer for each question. For example, 10/20 people got question 1 right, etc
• Give the class average

Your output file may look similar to this:
