Question
Chapter 8.9, Problem 8.7CP
Program Plan Intro
“enum” keyword:
“enum” data type is used to refer the enumerations in java. Variables, methods and constructors can be added to it. The main objective of “enum” is to define own data types. Every enum constant represents an object of type enum.
Example:
enum Color
{
Blue, Yellow, Red;
}
public class test
{
public static void main(String[] args)
{
Color c1=Color.Blue;
System.out.println(c1);
}
}

Write a program to help this teacher managing her students' test score. Use the following grading scale to assign a letter grade to a student. Test Score Letter Grade 80 - 100 A 70 - 79 B 60 69 C 50 - 59 0- 49 F Your program must have an array of string objects to hold the student names and an array of int to hold the student scores. Let the teacher determines the number of students and ask the teacher to enter the information for each student. Your program should have the following programmer-defined functions: getInput () - to read the students name and scores from user getGrade () - to determine the letter grade corresponding to the score getReport () - to determine the maximum, minimum, average and standard deviation of the scores Display an error message if the teacher enter mark below 0 or above 100, and keep asking for a valid value.

The computer chooses a random number using the following random generator function srand(time(NULL)); int r = rand() % 100 + 1; that creates a random number between 1 and 100 and puts it in the variable r. (Note that you have to include <time.h>) Then it asks the user to make a guess. Each time the user makes a guess, the program tells the user if the entered number is larger or smaller than its number. The user then keeps guessing till he/she finds the number. If the user doesn’t find the number after 10 guesses, a proper game over message will be shown and the actual guess is revealed. If the user makes a correct guess in its allowed 10 guesses, then a proper message will be shown and the number of guesses the user made to get the correct answer is also printed. After each correct guess or game over, the user decides to play again or quit and based on the user choice, the computer will make…arrow_forwardC++: Describe how the following call by reference works.
