Program: Please read the complete prompt before going into coding. Write a program that handles the gradebook for the instructor. You must use a 2D array when storing the gradebook. The student ID as well as all grades should be of type int. To make the test process easy, generate the grade with random numbers. For this purpose, create a method that asks the user to enter how many students there are in the classroom. Then, in each...
Create a Student grading system. You should use a person base class (stores the name of the student). Derive a student class from the person class. The student class stores the student ID. The student class should also store the students 3 exams (Test 1, Test 2, and Test 3) and calculate a final grade (assume the 3 tests count equally). Create an array of students for a class size of 15 students. You can use the keyboard to read...

Your assignment is to write a grade book for a teacher. The
teacher has a text file, which includes student's names, and
students test grades. There are four test scores for each student.
Here is an example of such a file:
Count: 5
Sally 78.0 84.0 79.0 86.0
Rachel 68.0 76.0 87.0 76.0
Melba 87.0 78.0 98.0 88.0
Grace 76.0 67.0 89.0 0.0
Lisa 68.0 76.0 65.0 87.0
The first line of the file will indicate the number of students...
in C++ You are to define a structure containing the id number, three test scores, and their average, for each student in a class of 20. The file pr2data.txt is included and contains the data. The program is to include the following: A function that reads 20 records of data from the file, finds the average for each student and prints each student’s record. A function that lists the ids and averages for all the students whose average is above...
c++
implement a student class
Determine the final scores, letter grades, and rankings of all
students in a course.
All records of the course will be stored in an input file, and a
record of each student will include the first name, id, five quiz
scores, two exam scores, and one final exam score.
For this project, you will develop a program named cpp to determine the final scores, letter grades, and rankings of all students in a course. All...
In this assignment, you will write a program in C++ which uses files and nested loops to create a file from the quiz grades entered by the user, then reads the grades from the file and calculates each student’s average grade and the average quiz grade for the class. Each student takes 6 quizzes (unknown number of students). Use a nested loop to write each student’s quiz grades to a file. Then read the data from the file in order...
Java: student directory GUI You need to implement three classes: Person Student StudentDirectory StudentMain Start by implementing Person and Student classes. Once you are sure you can serialize and deserialize and ArrayList of Students to and from a file, move on to building the GUI application. Person: The Person class should implement serializable interface. It contains the following: Person's first name (String) Person's last name (String) Person's id number Person's date of birth (Date) public String toString(): This method method...
