Textbook Question
Chapter 10, Problem 5PC
Course Grades
In a course, a teacher gives the following tests and assignments:
- A lab activity that is observed by the teacher and assigned a numeric score.
- A pass/fail exam that has 10 questions. The minimum passing score is 70.
- An essay that is assigned a numeric score.
- A final exam that has 50 questions.
Write a class named CourseGrades. The class should have a GradedActivity array named grades as a field. The array should have four elements, one for each of the assignments previously described. The class should have the following methods:
setLab: | This method should accept a GradedActivity object as its argument. This object should already hold the student’s score for the lab activity. Element 0 of the grades field should reference this object. |
setPassFai1 Exam: | This method should accept a PassFailExam object as its argument. This object should already hold the student’s score for the pass/fail exam. Element 1 of the grades field should reference this object. |
setEssay: | This method should accept an Essay object as its argument. (See |
setFinal Exam: | This method should accept a FinalExam object as its argument. This object should already hold the student’s score for the final exam. Element 3 of the grades field should reference this object. |
toString: | This method should return a string that contains the numeric scores and grades for each element in the grades array. |
Demonstrate the class in a program.

please help me with the pseudocode for this I need it.
Student Name
Student Id
Student Grades (an array of 3 grades)
A constructor that clears the student data (use -1 for unset grades)
Get functions for items a, b, and c, average, and letter grade
Set functions for items a, n, and c
Note that the get and set functions for Student grades need an argument for the grade index.
Need another class which will contain:
An Array of Students (1 above)
A count of the number of students in the use
You need to create a menu interface that allows you to:
Add new students
Enter test grades
Display all the students with their names, ids, test grades, average, and letter grade
Exit the program
(TicTacToe Class) Create a class TicTacToe that will enable you to write a complete programto play the game of tic-tac-toe. The class contains as private data a 3-by-3 two-dimensional arrayof integers. The constructor should initialize the empty board to all zeros. Allow two human players.Wherever the first player moves, place a 1 in the specified square. Place a 2 wherever the second player moves. Each move must be to an empty square. After each move, determine whether the gamehas been won or is a draw. If you feel ambitious, modify your program so that the computer makesthe moves for one of the players. Also, allow the player to specify whether he or she wants to go firstor second. If you feel exceptionally ambitious, develop a program that will play three-dimensionaltic-tac-toe on a 4-by-4-by-4 board. [Caution: This is an extremely challenging project that couldtake many weeks of effort!]
Task #1 Average Class-Create a class called Average according to the UML diagram.
Average:
-data [ ] :int
-mean: double
+Average( ):
+calculateMean( ): void
+toString( ): String
+selectionSort( ): void
This class will allow a user to enter 5 scores into an array. It will then rearrange the data in descending order and calculate the mean for the data set.
Attributes:
-data [ ]— the array which will contain the scores
-mean — the arithmetic average of the scores
Methods:
-Average — the constructor. It will allocate memory for the array. Use a for loop to repeatedly display a prompt for the user which should indicate that user should enter score number 1, score number 2, etc. Note: The computer starts counting with 0, but people start counting with 1, and your prompt should account for this. For example, when the user enters score number 1, it will be stored in indexed variable 0. The constructor will then call the selectionSort and the calculateMean methods.
calculateMean — this is a…

You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]arrow_forwardQuestion: Write a program to Simulate a game of tic tac toe.
