Need help with C programming homework!

Several functions are complete, the picture shows which need to be completed still. The given code is provided below.

White a program called registrar.c that is used to create courses at the universty, enrol students at university and register students for university. Pay attention to the comments. The Readme txt fle has list of input commands that you can copy and paste to make it easier for testing The starting template can be found in the assignments directory on https ligithub.com/pisanuwicss132 A typical interaction (as provided in Readme tbdt for FULL testing) is as follows Enter the name for university: UwB Welcome to the UWB menu 1. Display information about the university 2. List all courses 3. Add a course 4. Enroll a new student 5. List all students 6. Register a student for a course 7. List all students enrolled in a course 10. Exit Enter command: 3 choice is 3 Enter the name for cour e: 132 Weloome to the UWB menu 1. Display information about the university 2. List all cour es 3. Add a course 4. Enroll a new student 5. List all acudents 6. Regist r a s=uden: for a course 7. List all s=udents enrolled in a eurse
