Grade Book
A teacher would like to assign a letter grade to a student, based on student's test score. 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 program should also be capable of…
8. Grade Book
A teacher has five students who have taken four tests. The teacher uses the following grading
scale to assign a letter grade to a student, based on the average of his or her four test scores:
Test Score
Letter Grade
90–100
A
80-89
B
70-79
C
60-69
D
0-59
Write a class that uses a String array or an ArrayList object to hold the five students' names,
an array of five characters to hold the five students' letter grades, and five arrays of four
doubles each to hold each student's set of test scores. The class should have methods that
return a specific student's name, the average test score, and a letter grade based on the average.
Demonstrate the class in a program that allows the user to enter each student's name and his
or her four test scores. It should then display each student's average test score and letter grade.
Input Validation: Do not accept test scores less than zero or greater than 100.

- CASE STUDY#:Grade Register Write a grade register program to keep and process the grades of students. The program contain a class called GradeRegister. This class has two data members known as CourseName and an array of integer called Grades. The array Grades keep the grades of students of the same course. GradeRegister class have three methods as GetHighestGrade(), GetLowestGrade() and GetAverageGrade().The method GetHighestGrade return the maximum grade as integer from the array Grades and GetLowestGrade return the minimum grade value as integer from the array Grades. The GetAverageGrade method will return the average of grades from Grades array as float value. The parameterized constructor inside GradeRegister class will take two parameters to initialize the two data members of same class as mentioned before. Write a driver class GradeRegisterDriver to declare and initialize an integer array for grades and pass through the GradeRegister class constructor along with the course name.…arrow_forwardc++ The program reads data about two contestants from the keyboard and displays the scores and the winner of the two contestants. The program uses a data structure called Contestant for storing the scores of a contestant and a set of functions related to the data structure for processing the scores of contestants. The data structure, Contestant, contains an int variable for the contestant's ID and an array of doubles for the scores given to the contestant. Each ID must be a positive integer. Each score must fall in the range from 0.0 to 10.0 inclusive. Your job is to complete the program so that its output matches the expected outputs when testing with the same test data. First, complete everything that is required of you at the top of the file. Then complete those and only those incomplete functions according to their descriptions. Each of the incomplete functions has the following line in its body. // Write your code with comments . . . Remove that line and complete the function.…arrow_forwardAddy basics Javaarrow_forward
- Lotto Program C++Write a program that simulates the Powerball lottery. In Powerball, a ticket is comprised of 5 numbers between 1 and 69 that must be unique, and a Powerball number between 1 and 26. The Powerball does not have to be unique. Hint: You can use an array to represent the 5 unique numbers between 1 and 69, and an integer variable to represent the powerball. The program asks the player if they'd like to select numbers or do a 'quickpick', where the numbers are randomly generated for them. If they opt to select numbers, prompt them to type the numbers in and validate that they are unique (except the powerball), and in the correct range. The program then generates a 'drawing' of 5 unique numbers and a Powerball, and checks it against the user's lotto ticket. It assigns winnings accordingly. Because it is so rare to win the lottery, I suggest hard coding or printing values to when testing the part of the program that assigns winnings.arrow_forwardC++ Coding Write a program that asks a teacher to enter the student's and the grades received on her quarterly exams. The datatype for the student's name could be a string and the four grades should be entered in an array of data types int. Test scores are on the base of 100. The main() functions describe the average function with the following title line: double avg( int grades[] , int cap ): The program prints the student's name, her four grades, and her average grades. The main() function also uses the following print function: void print( int grades[], int cap);arrow_forwardClass and Data members: Create a class called Student that stores a student’s grades (integers) in a vector (do not use an array). The class should have data members that store a student’s name and course for which the grades are earned. Constructor(s): The class should have a 2-argument constructor that receives the student’s name and course as parameters and sets the appropriate data members to these values. Member Functions: The class should have functions as follows: Member functions to set and get the student’s name and course variables. A member function that adds a single grade to the vector. Only positive grades are allowed. Call this function AddGrade. A member function to sort the vector in ascending order. A member function to compute the average (x̄) of the grades in the vector. The formula for calculating an average is x̄ = ∑xi / n where xi is the value of each grade and n is the total number of grades in the vector. A member function to determine the lowest…arrow_forward
