- OOP Lab #10 Using your knowledge in c++. Demonstrate a project that contains a file called "Class Grades.txt", then read student's names and Grades from the file and store them into separate arrays, and then do the following: 1. Firstly, you create a ID string array called “names" to store each student name. 2. Secondly, you create a 2D int array "grades" to store student's original quizzes Grades. the array has 7 columns, the original 6 Quizzes Grades must be stored in the following columns : [0,1,2,3,4,5]. Store in the last column the average of the Grades. 3. Thirdly, Get the grades from the array called "grades", then calculate the average and determine the letter of that final grade. Hint: The following functions are required: 1. "PutGrades" to read and save data into both "names" and "grades" arrays. 2. "Grades Average" to calculate each student Grade average, The grades average must be repented as letters e.g : A>= 90 , b>= 80 .. Then find the Maximum and Minimum Grade.

Remove an item from the inventory manager. Re-stock an item in the inventory manager. Display the items in the inventory manager. Search for an item in the inventory manager by at least two criteria (name, price, quantity, etc.). Test the inventory manager class with a driver program or unit tests. This may be a console application.
- Code in C++ Language As a cashier, you would always hate those times when customers choose to take back their order since you'd always summon your manager and yell, "Ma'am pa-void!" No matter how you hate it, you always have to do it since you have no other choice. Given (1) an array of prices of the items, (2) another array of the items the customer wishes to take back, and (3) the customer's payment, print the change of the customer. Input: The first number indicates the number of items "n" brought to the cashier. The next "n" numbers are the prices of the items. The next number indicates the number of items "m" that the customer wants to take back and not proceed. It is assured that 0 <= m <= n. The next "m" numbers are the items to be void that ranges from item 1 to item "n". The final number is the customer's payment. It is also assured that the given payment >= final price of items. INPUT: 5 103.65 650.95 10.25 1067.30 65.18 2 1 5 2000.00 Output: The change…Write complete C++ program to simulate a Magic 8-Ball, which is a fortune telling toy that displays a random response to a yes or no question.

Ask me later.Write a C++ program that will display multiple-choice trivia questions, accept the user's answers, and provide a full key and a score at the end. Design and implement a class called Question. The Question class contains the following information: a stem (the text of the trivia question) an array of 4 multiple choice answers (the text of each possible answer) the letter of the correct answer (A, B, C, or D), called the key. This class will be used to represent trivia questions in a trivia game. The following operations should be available for Question objects (use the provided names). Construct a Question with no values (use empty strings for stem and answers and 'X' for the key). Construct a Question given its 3 components (). setStem: Set the stem question. getStem: Return the stem question. setAnswers: Set the 4 answers given an array. The answers will NOT include the letter (A, B, C, or D). getAnswer(i): Return the single answer at index i. setKey: Set the key letter. getKey:…
- for java please Please submit the pseudocode of your program for your project below. Need a class which will contain: 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 number of students in 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 Add comments and use proper indentation. Nice Features: I would like that system to accept a student with no grades, then later add one or more grades, and when all grades are entered, calculate the final average or grade. I would like the system…Assignment A scientist has developed a mathematical model for a physical process, and he wants to check how good is model is. To evaluate the correctness of his model, he wants to test the results of his model under certain parameters and compare them with experimental results. Write a program that first reads the number of tests (testCount) as an int followed by the results of each test according to the model as a double array (testModel) and finally the results of each test according to experiments as a double array (testExperiment). Then, the program should calculate the error of the model by evaluating the average of the absolute values (i.e., mutlak değer) of the differences between the model result and experimental result (see formula below) using a function. ItestModel,- textExperiment, testCount NOTE: Individual absolute value of the difference between the model value and the experiment value calculations MUST be done in the function. Every other functionality MUST be done in…Pseudocode for Java code Write the algorithm in pseudocode for a method that accepts three parameters: an integer array, an integer representing the number of valid values in the array, and an integer representing a factor. The method will count the number of valid values in the array that are multiples of the factor and will return the count. There is a Java operator that might be very helpful in solving this problem. Testing Above problem: Assuming that the first two parameters are an array containing 4, 10, 15, 12, 8, 20, 100, 25, 32, 7, 28, and 48 and the number 12, come up with three good test cases for the factor and the return value. factor numMultiples
- In Java Develop a function to create arrays of random integers. The caller sends the desired size of the array and the minimum and maximum values to generate for the array. The function returns the specified array. For example, with arguments of 10, 1 and 100, the function returns an array of 10 random integers from 1 to 100. With arguments of 5, -10 and 10, the function returns an array of 5 random integers between -10 and 10. Develop two functions: one to display arrays of integers and another to display arrays of Strings. In both functions, display the length of the array, then display the array index followed by the array value at that index. Two examples are below:a. Given the integer array {2, 30, 9, 48, 5, 72, 3}, the function displays:Array has 7 elements[0]: 2[1]: 30[2]: 9[3]: 48[4]: 5[5]: 72[6]: 3In C# Use a one-dimensional array to solve the following problem. Write a class called ScoreFinder. This class receives a single dimensional integer array representing passer ratings for NFL players as an argument for its constructor. The test class will provides this argument. The test class then calls upon a method from the ScoreFinder class to start the process of finding a specific rating, which will be provided by the user. The method will iterate through the array and find any matching values. For all the matches that are found, the method will note the index of the cell along with its value. At completion, the method will print a list of all the indices and the associated scores along with a count of all the matching values.in C++ : You are given an array of integers representing asteroids in a row.For each asteroid in the array/row, the absolute value represents its size, and the sign represents its direction (positivemeaning right, negative meaning left). Each asteroid moves at the same speed.Find out the state of the asteroids after all collisions. If two asteroids meet, the smaller one will explode. If both are thesame size, both will explode. Two asteroids moving in the same direction will never meet. Example 1:Input: asteroids = [5,10,-5]Output: [5,10]Explanation: The 10 and -5 collide resulting in 10. The 5 and 10 never collide. Example 2:Input: asteroids = [8,-8]Output: []Explanation: The 8 and -8 collide exploding each other.
