C programming Question. Anyone who answers this Q i will give him my 10 points always when answering my Qs.?

Write a program that displays a menu that shows the following options:


a. Enter number of grades in class


b. Enter grades of class


c. Output average of class


d. Exit program





Choosing a menu option will cause some functionality to execute in order to have a program that calculate the average grade of a class:





a. Enter number of grades in class


Should allow the user to enter the number of grades to be inputted by the user. Do not allow the user to enter a 0 or negative number by displaying “invalid number” and prompting him to enter the number again...





b. Enter grades of class


Should allow the user to enter the number of grades of the class (you should calculate the sum)





c. Output average of class


Will print on the screen the average of the grade entered





d. Exit program


Will cause the program to terminate.

Reply:So let me understand... All we have to do is write this program for you and you'll give us 10 points?
