Computer Assignment # 2
Due Thursday November 10th
Create an ASCII file, test.txt, as shown below using text editor. It contains the results of a true-false exam given
to a group of students. You may assume that the number of students will always be less than 20. The first line
contains the key answer representing the 10 correct answers. Starting from the second line, each line of the data
file contains the student identification number and the student’s answer to 10 true-false questions. A sentinel
value of 9999 has been used.
Write a program that reads as input the file test.txt. The program should start by readng the correct answer from
the first line into a 1-D character array named correct_answers, then do the following tasks:
1. Read the students ID numbers into a 1-D integer array named ID, and read each student’s answers
into a 1-D character array containing the answers for the current student, named current_answers. The
number of students, num_students, should be determined in the process.
2. While reading the data in (1), compute and store the number of correct answers for each student in a
1-D integer array named scores.
3. After reading all the data, determine the average score, AvgScore.
4. Finally, print a three-column table on the screen that displays the ID number, the score, and the grade
(Pass or Fail) for each student.
The grades should be determined as follows: If the score is larger than AvgScore then the grade is Pass; otherwise
the grade is Fail.

Note:
Your program must be written so that it could process a file with any number of students (less than 20) terminated
with a sentinel value of 9999.
Adequate comments should be placed throughout your program to briefly describe it statements.
