Write a C++ program that takes a list of students grades for a given course (a grade is a positive integer between 0 and 100), entered by the user through the keyboard. The program continues to ask the user to enter grades until the user enters -1 indicating the end of the list. When the end of the list is encountered, the program computes the course's average grade, and prints out the equivalent Letter average grade of the class according to the following: A average >= 90 Excellent Performance B average >= 80 Very Good Performance Caverage >= 70 Good Performance D average >= 60 Average Performance F otherwise Not Good Performance Use a cascaded if-else statement to determine the Letter average grade. In addition, use a "switch-case" statement to output the proper class performance description (that is excellent, very good, etc)
