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

Explanation / Answer
hai,
I help you some part.
//line 34, 55 put a space in between integer and initialization.
//line 29 you use system("pause");
/* if you are using system("pause"); is takes too time to execute and wait response from window.
you could use this code
*/
check the {} braces.
check the function declaration.
I clear this above said error and i get linking problem only.
check out.
