Project 7

Due: Dec 9

Requirements Specification

Write the C code for recording and performing statistics on student grades. Use functions and arrays to do this project.

Your program should do the following:

  1. There are total 10 different grades per student. 4 quizzes, 4 projects and 2 exams. Maximum grade for each is 100.
  2. The maximum no. of students in the class can be 20.
  3. Each student is identified by a unique 4 digit number.
  4. The program will print the grade table for the class as well as compute and print statistics for the given grades.
  5. The input is to be read from an input file which gives the number of students in the class (<= 20) and all the grades.
  6. The quizzes are worth 5% each, projects are worth 10%each and exams are worth 20%each in the final grade.
  7. Letter grades are: A above 90, B for 80 to 89, C for 70 to 79, D for 60 to 69 and F for less than 60.
  8. Use functions that you need to do this project. Don't do all the work in main. You will lose 50% of the grade if you do that.
  9. Use only one and two-dimensional arrays to do this project.

-- For taking input from an input file use UNIX redirection.
-- Create a file that contains all the grades. Then compile your code. Run the following command 'a.out < grade_filename'.
-- Don't put printf's in the code that prompt the user for input because it is coming from a file. Only print a table similar to the example output.
-- While you are writing your program, you could ask for data from the keyboard. But, the final version of your program should not ask the user for data.
-- You should remove any statements that ask the user for data so that they are not printed to the screen by your final version.
-- Use the input file similar to the one shown below. This is  the input file for the sample output.
-- The first line gives the number of students in the class (4 in this case). Next comes the SSN for the first student (1023) followed by his 10 grades.
-- Then the SSN (4532) for the next student and his grades and so on for all the students.
-- The output should not print the scores for all the 20 students but only for the number of students specified in the input file.
