Description

Department of Computer Science
In this project, you will maintain the information of different courses using AVL trees. Your program will read the courses and their relevant information from a file named courses.txt. As well, the user should be able also to enter new courses into the program with their relevant information. Please use the following format for inputs
Course:CreditHours#CourseCode#Department/topic1, topic2, …, topicN where N is the number of topics covered in the course and it is ≥ 1.

Example of input courses:
Course:CreditHours#CourseCode/topic1, topic2, …, topicN
Data structures:4#COMP2421#Computer
Science/recursion, time analysis, linked lists, stacks, queues, trees, bst, avl, splay, b_trees, hash, heaps, sorting, graphs
Introduction to programming:3#COMP133#Computer Science/algorithms, introduction to c, functions, selection, loops, pointers, arrays, structs
Introduction to French:3#FREN111#French Language/letters, numbers, greetings, grammars, statements

To keep track of the courses, you should store them in an AVL tree data structure. The key that will be used by the AVL tree is the course code.

The following operations should exist in your application:
1. Read the file courses.txt file and create the tree.
2. Insert a new course from the user with all its associated data.
3. Find a course and support updating of its information.
4. List courses in lexicographic order with their associated information (credit hours, IDs, and topics).
5. List all topics associated with a given course.
6. List all courses in lexicographic order that belong to the same department.
7. Delete a course.
8. Delete all courses that start with a specific letter.
9. Delete all courses belong to a given department.
10. Save all words in file offered_courses.txt

Grading policy:
1. Your application should have all functionalities working properly. Twenty marks will be graded for the functionality of the project;
2. The following notes will make up the remaining 10 marks of the grade:
a. There has to be adequate documentation and comments in the code (i.e., functions, loops, etc.);
b. Your code should follow the code convention (i.e., spaces, indentations, etc.); and
c. Your application should contain a menu to allow the user to select which option (s) he would like to run.

Notes and submission instructions:
1. This is individual work. It should represent your own efforts. It is fine to discuss your work and to ask your colleagues, but you are not allowed to copy/paste the work of others or give your work to anyone else. You are not allowed to post/copy from other websites and/or social media and this will be considered as cheating.
2. Any plagiarized code will not be marked.
3. Document format. Please submit only the code file (c file) containing the code of your project. Please rename it as follows:
“P2_YourStudentID_FirstNameLastName_SectionNo.c”.
4. Input/output file name. Make sure that the input/output file names are the same as in the specifications.
5. Include your full name, student ID, and section number in the beginning of your file.
6. Please do not compress the file, only the C-file is needed.
7. Files not following the convention in point 2 will not be marked.
