Question

The purpose of this project is to create a fee invoice application for students attending Valence Community College. The main menu for your application must have the following options. 1- Add a new student 2- Add/Delete a course for a student 3- Search for a student 4- Print fee invoice For every option, you must have a separate function. Feel free to add helper functions as needed Additional Information It costs 120.25 dollars per credit hour in addition to $35.00 charged for health and id services. Valence Community College offers the following course: CRN 4587 4599 8997 9696 1232 9856 8520 8977 Course MAT 236 COP 220 GOL 124 COP 100 MAC 531 STA 100 TNV 400 CMP 100 Credit Hours 4 2 Note that we are considering the names of the students in this project Furthermore, a student can take up to 4 courses this time!

Please have the code run as shown in the sample run. Use as many functions as possible and make the main function as clean as possible. Use C for language
