Write a C program that follows the protocol below. Thank you.

Learning Outcomes: Functions and Pointers Read carefully before you start coding! At Valence community college, a student can't take more than 3 courses under the constraint of having no more than 7 credit hours. The purpose of this assignment is to construct a fee invoice for a student. This requires the input of Student's id as integer and the course numbers It costs 120.25 dollars per credit hour in addition to $35.00 charged for health and id services. In this project, functions must be used (no redundant code is allowed this time) A hint is provided at the end of this document. Add functions as you see fit. Bottom line: Have the cleanest (minimum lines of code possible) program. This is a great opportunity to work in groups by having each student taking care of function or two and then meet to put everything together...
