PROJECT DOCUMENT

Instructor: Bashir M. Ghandi Due: 2^nd May 2000

Note:

· No grade will be given for any copied project for all the parties involved.

· No grade will be given if you do not come for the demonstration.

An ICS 201 Instructor wants to maintain the grades of his students in four quizzes. The grade information is stored in a text file GRADES.TXT in the format:

ID NAME [maximum 30 characters] QUIZ1 QUIZ2 QUIZ3 QUIZ4

Originally, before all the quizzes have been taken, the file contains the following information:

900000 ALI ISSA MUHAMMAD -1.0 -1.0 -1.0 -1.0

900025 MUSLIM HASAN -1.0 -1.0 -1.0 -1.0

900032 QASIM ZAID UMAR -1.0 -1.0 -1.0 -1.0

900047 KARIM OMAR SAAD -1.0 -1.0 -1.0 -1.0

900058 MUSA SAID -1.0 -1.0 -1.0 -1.0

900060 OMAR ZUHER -1.0 -1.0 -1.0 -1.0

920030 UBAID HUSAIN YAZID -1.0 -1.0 -1.0 -1.0

930541 AYMAN OMAR -1.0 -1.0 -1.0 -1.0

where -1.0 indicates that the quiz has not been taken.

Write a well structured, interactive C program which displays a menu with the following options:

1. Display the grade information for all the students.

2. Display the grade information for a particular student.

(If the given ID is not in the file an error message should be printed)

3. Enter quiz grades for all students for a particular quiz.

(A quiz grade less than 0.0 or greater than 100.0 should be rejected and the user prompted to enter another grade. A quiz number other than 1,2,3, or 4 should be rejected and the user prompted to enter another quiz number)

4. Change a particular quiz grade for a particular student.

(If the given ID is not in the file an error message should be printed. A quiz grade less than 0.0 or greater than 100.0 should be rejected and the user prompted to enter another grade)

5. Find the quiz average for a particular student.

(If the given ID is not in the file an error message should be printed.)

6. Find the average of a particular quiz.

(A quiz number other than 1,2,3, or 4 should be rejected and the user prompted to enter another quiz number. If a quiz has not been taken an error message: QUIZ NOT TAKEN should be printed)

7. Add the information for a new student.

(If the given ID already exists in the file an error message should be printed)

8. Delete the information for a particular student.(If the given ID does not exist in the list an error message should be printed)

9. Quit
