Participation Assignments: Assignment 01: MO2 Advanced Average: NOTE: Make sure and include comments in your program. At a minimum it should include the author's name and a short program description. This week we will rewrite the Advanced Average code from CSC 1613 using recursion(No While Loops or For Loops). This program will take as input an arbitrary number of grades. The program should keep track of the grades until a sentinel value has been entered. The value of -1 should be the sentinel value and should not be counted in average. When the sentinel value is detected, the program should calculate the average and print out the appropriate letter grade. To submit this assignment, please click Advanced Average Using Recursion.
