Average Student Grade HW (Please Help ASAP)

Rgillooly91 (8)
Hello guys,

I have a homework assignment due tomorrow. I put my code below but I have several errors which I can't seem to figure out why :(. The assignment is below and below that is my current code. It is due tomorrow so I would GREATLY if someone can help me ASAP

"An Instructor needs a computer program that can compute course-grades for his classes. When the program runs, it should request last name, two test grades and one homework grade for each student at a time. IT should then compute the course-grade by using the following formula: Course-grade = 60% of average of tests + 40% of homework grade.
There are 5 last names and 3 grades for each student. It should be rounded to the nearest integer. Then print the name of the student, course grade as a ninteger number next to it, and a course grade in letter form next to that. Letter grade is determined by the following formula:
90+ - A
80-89= B
70-79= C
60-69= D
Below 60= F
Class size is unknown. Therefore, you need to use a sentinel-controlled loop to repeat this process as long as there is more data.
My code is below folks. Please help me I can't figure out why it isnt running

Would be helpful if you posted the errors you have.

You should pick a format to follow, your code is very hard to read as it currently is. https://en.wikipedia.org/wiki/Indent_style

You can't have two main functions.
You shouldn't be defining a struct in a function in this case.
